Guest guest Posted January 18, 2001 Report Share Posted January 18, 2001 Well, I wasn't going to mention this until I'd thought this through some more, but since you brought it up, at the risk of sounding like I'm saying "me too" ... me, too. I've been putting together a detailed panchanga for the Chicago area for the year beginning in March, and for the past several weeks, I've been scratching my head trying to reconcile the lunar longitudes I've been getting from GJ 2.26 with those I've been getting from Winstar, Halloran AstrolDeluxe, RedShift 3 (planetarium software), my own software which is based upon the algorithms specified in Meeus, and the U.S. Naval Observatory's almanac. I haven't gotten the same answer twice, even when using the tropical zodiac, but it does seem that GJ disagrees the most, and only on the lunar longitudes--everything else is within a minute or so. As I recall, the discrepancy is generally less than about 30 minutes of arc, so it doesn't keep me awake at night--but then again, half a degree of lunar longitude is about, what, an hour of clock time? For sub-sub periods, of course, that's significant. My guess--and it's just that--is that one or more of these products are not calculating the solar pertubations of the moon correctly, since that accounts for an error on that order of magnitude. Or, perhaps GJ uses more traditional algorithms (such as from the Surya Siddhanta). Or, I'm totally out of line. Das? So, for what it's worth, I've found that WinStar comes the closest to agreeing with the USNO (which I am reluctant to dispute), differing by at most half a sidereal minute on the hour angle. Halloran differs by only a tiny fraction more on the very few dates I've compared (I've always liked his software). Dunno about SF; perhaps Chris or someone with SF would plug-and-chug that for us. So, if we were to accept that, that yields a tropical longitude of 6 Aqu 50 mnts 37 secs, Lahiri longitude 13 Cap 20 mnts 52 secs. For comparison, the Para Research ephemeris gives a tropical longitude of 6 Aqu 52 after linear interpolation. Your moon, then, is about 25.1% 22-Sravan, for calculating your planetary periods. jpd PS Speaking of the Surya Siddhanta, is there a better English translation than the Burgess of 1858? One could perhaps excuse my pessimism at a translation by one with religious conversion motives. Quote Link to comment Share on other sites More sharing options...

My personal opinion is that these should be played around with, and I find this to be a more accurate position when considering dashas etc. I also think it seems logical, as it considers the Moon's position from the place of birth, not a generalised point for the whole world. The bad news is that if you want to change to geocentric again, after doing the correction in the main prefs window, you'll have to recalculate all your charts.

Without correcting for parallax, GJ yields the same longitude as just about everyone else. I remember playing around with parallax correction some time ago, but didn't notice much of a difference, presumably (now) because the moon was close to transiting the meridian, which is entirely a function of not grasping the effect of parallax on close planets. So, Angie, it's back in your lap. Parallax is the apparent distortion caused by looking at a nearby object from two different perspectives; GJ can compute (your option; it's probably the default) the apparent longitude from your location or from a hypothetical earth center (prolly the default on others). If you believe that parallax has an effect, go with what GJ tells you with its parallax correction on; if you don't, go with what the others are saying. > Haribol!

Dear Pursottam, This brings up the the point that Robert and I are discussing. The parallaxed moon does make sense if you look at things (astro)(physically). this implies that planetary positions should be taken relative to the actual spatial location of the place of birth - and that some geometrical/physical influence is involved. That "rays" impinge on the baby and "determine" its fate, like the genes determine the physiological development AND EVEN SAY HOW MANY TIMES ITS CELLS WILL SPLIT, HOW LONG IT CAN LIVE! But the genes were already there, before birth! By similar logic the sun should also be paralled: it appears above the horizon before its physical centre. For births at sunrise or sunset this can be a factor to consider. Even Ascendant is a questionable matter. The ecliptic degree corresponding to the point due east at birth is not always the the degree rising at the same latitude. AS an air-conditioning engineer I was faced with a peculiar situation: For all northern latitudes above the tropic of cancer the sun is always SOUTH. In fact the sun at MC was often called "southing", for when the sun stood highest at noon, it was exactly in the south. According to this, for a house with its northern wall running east to west, this wall should ALWAYS be in the shadow. But this is not the case: early in the morning and late in the afternoon the sun shines obliquely on this wall and warms it up! The "location maps" - John Dro - etc illustrate this difference. The East Point is different from Ascendant! In short, the ascendant is "geocentric", not local! If so, it is best to stick to geocentric values for all bodiues. If mean Rahu is more valid than true Rahu, why should the apparent moon be better than its theoretical position? We are children of the earth and what affects the earth is what affects us. Tzere are "mysteries" even in everyday life: why does an Eskimo feel warm in an igloo of ice? Why does an iced up fridge "refuse" to cool food quickly? There are explanations, but these are not apparent to common sense. The question of BHAVAS HAS NEVER been solved. For very northern latitudes it is very difficult to find a suitable system. The best according to tradition is the equal house in jyothish, dividing at 30 degree intervals, with the cusp as mid point. I feel that this is is not right: the MC shoud be the mid-point of the 10th always, with equal divisions. This will make the 4th from the MC the lagna, the Ac a point of sensitivity etc. ...... You, Pursottam, are the "brains" of our community and are young. Your Mercury is very close to the sun: brilliance, but afraid of "independent" thinking. The great jyothishis lived till some 2000 years ago, but the tradition was broken. Now and then some have somehow kept the old tradition alive. But a person like you should pick up the old thread and bring NEW LIGHT! Defending and quoting is not progress, but ADDITION is. BE THE VARAHAMIHIRA OF THIS AGE! Try new fields! Another question: the parallaxed moon either advances or retards the dasas. If the results are better only by retardation or advance, the ayanamsa is probably wrong, unless the amount varies. If only small differences are found, the TOB may be incorrect. Before arriving at conclusions one must check cases where the variation is appreciable - and explanations are relatively simple. By using all the vargas and transits and upagrahas one can ALWAYS FIND A REASON FOR ANY EVENT, EVEN WITH TOTALLY WRONG TOB! Sorry to say this, but it is true! Proving any "rule" is not just bringing suitable evidence, but in showing how the rule explains cases which apparently defy the rule! regards Mani Quote Link to comment Share on other sites More sharing options...

It is mostly done, and already has the following features. All times use Local Time. Takes DST into account. Start times for tithi, amrita-yoga sun-moon yoga, tithi, nakshatras Start-end times for local and global eclipses. (For solar eclipses, tells you how much of sun will be eclipsed at peak...will tell you when it will be visible from your vantage point) Start times for changeover of planets into different houses, and start/end times for retrograde motion Takes extra/missed lunar months into account Gives sunrise, sunset, moonrise, moonset times. Rahu kalam, Gulika kalam, Yamagandam based on local sunrise/sunset Finds julian date for event based on gregorian, solar or lunar calendar. Festival generation code is not hard-coded. Adding a festival/event is as simple as adding one line to a file. Uses the Swiss Ephemeris for calculations Generates a professional looking pdf file (This is not meant as an ad. I have no intentions of selling the program. I will make the pdf files for a wide variety of locations freely avaiable. I am writing this program because there is no good panchangam available for my area, and I don't want to hand calculate it each year.) I am having problems with the rules for calculating the julian day of some festivals, and am hoping the knowledgable people in this list can help me, or point me to the appropriate place. If a festival takes place during the day on a tithi for a given month, and that tithi occurs on two consecutive days, both with a prevalence of that tithi between sunrise and sunset, on which day should the tithi occur? If this tithi takes place twice during the month (once at very beginning, and then at very end), on which of these occurences will the tithi occur? I am hoping that there are standard rules to determine this, and that it is not different for each festival. If it is the latter, pointers to appropriate resources will be greatly appreciated. yours, ajit -- Ajit Krishnan ajit http://publish.uwo.ca/~akrishna Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 19, 2001 Report Share Posted January 19, 2001 Hey Angie and All: Pursottam is right on this: disprepancies between Moon positions in GJ and other programs are most likely due to the parallax correction feature being left on in GJ. I checked Solar Fire and it has the standard geocentric Moon at 13Cp20 41 while parallax position is 13Cp52 59 (lahiri). So there's nothing "wrong" with GJ at all. But I think we knew that already. :-) Chris Quote Link to comment Share on other sites More sharing options...

AS an air-conditioning engineer I was faced with a peculiar situation: I agree. If possible, my personal feeling is that we should in fact have evrything parallaxed. However, from the many discussions we've had on this subject on the list, I remember reading that it only makes a significant difference in the case of the Moon. How one defines significant is debatable, but one assumes that it would mean more than a couple of minutes of arc. Of course, many rectify charts to get certain lagnas in the Varga's. However, who knows, perhaps it's not the TOB that's wrong - just the ascendant! Also, while no direct references are given in the Jyotisha Shaastra's, it is mentioned in the Siddhanta texts that one's calculations should regularly be compared to those visible in the sky, to ensure accuracy. To me, this seems to support parallax. > > The question of BHAVAS HAS NEVER been solved. For very northern latitudes it is > very difficult to find a suitable system.

I know what you mean here. If there's onw thing you learn from just gbasic western astrology, it is how sensitive points like the midheaven are. It's amazing the way that transits to these points bring about results. And of course if one does use a house system such as that of Sripati, one sees all this in Jyotish as well. However, it is very difficult to see how all this plays a role in the North Pole or whatever. Who know's? Maybe it doesn't matter that all the lagna's don't rise regularly there. Perhaps the fact that so few are born there means that those who are were destined to have those particular angles. It would certainly be fun to get charts of extreme northern longitudes to see how transits to the four angles affects the lives of the owner's. Of course, for now at least, the equal houses of Jyotish are a tried and tested system, that work. > Another question: the parallaxed moon either advances or retards the dasas. If > the results are better only by retardation or advance, the ayanamsa is > probably wrong, unless the amount varies. If only small differences are found, > the TOB may be incorrect. Yes I know what you mean. Generally, with a little rectification, this issue does not seem to make a huge difference. However, in other cases such as my own, one can rectify (but not too much - I know my TOB's not that far off), and still won't get an expected dasha. You can of course play with Ayanamsha, but this just seems to mess everything else up. Lahiri may not be spot on, but it's not that far off either. The Mrtyu Bhaga's are of course an extremely interesting area for ayanamsha research. Also, while largely based on standard Vimshottari dasha's, I also tend to find the Moon's position in Varga's to be more accurate. And the smaller Nakshatra dasha's, such as Yogini, or Tribhagi Vimshottari etc. all of which help add flavour, and strength to Vimshottari interpretation also seem to work better IMHO. Of course, one is regularly bound to get some charts which do not fit the parallax positions (e.g. Robert's :-), or those, such as mine, which don't fit geocentric. Having started with geocentric, and sensing something wrong right from the first glimpses into my own dasha's, I have to say that in general I feel parallax works better. > Before arriving at conclusions one must check cases > where the variation is appreciable - and explanations are relatively simple.

However the trick is in starting with a nice simple explantion with the Rasi chart, and then going into the divisionals to find confirmation and support that changing to parallax really has made things a lot easier to see. In my own chart, events are so blatent that given a choice anybody with a little knowldege and experience of Jyotish would have to pick the parallax dasha sequence, if they were given a choice between the two, together with event times.

Dear Grey Cells! The parallax differences would be approx.: Mercury and Mars: 15 seconds of arc Sun (away from horizon) : 9 secs Venus: 35 secs jupiter: 2secs saturn :1sec. Moon: max around 1 degree and 2 secs. For jupiter and beyond the difference is less than the accuracy of calculation! The amount of accuracy for is sun 1 sec, moon 10 secs, others between 3 and 5 secs. These differences would mean an equivalent difference for sun about 4 minutes in TOB, neglecting initial error. mercury and mars: about 6 minutes, for venus about 15 minutes, for moon 2 hours. Sun at horizon can equal about 20 minutes (I believe!). > Of course, many rectify charts to get certain lagnas in the Varga's. > However, who knows, perhaps it's not the TOB that's wrong - just the > ascendant!

Not necessarily. This ancient injunction holds good today, even otherwise, astronomically. The dynamic system of the solar system is stable, but is continually subject to aberrations. We have no really fixed points of reference, nothing ever repeats itself. Every orbit is only a mean orbit and the relative positions of the orbits either rotate or oscillate. The planets keep to their orbits only within limited widths, but not exactly in the middle as a smooth curve. all calculated positions have to be periodically corrected and used as "new" starting points. The Nadis illustrate this: the positions they give for Saturn and venus especially do not tally with positions calculated by our programmes. The calculations as per Surya siddhantha also do not give the positions given by programmes. Hence one must conclude that the ancient writers conceded that their calculation methods were not perfect and valid only for a relatively short period of time, that periodic corrections were needed! They did not claim to have spoken the last word, but called for continuous study and improvement - using scientific methods, the first of which is observation! > > > > The question of BHAVAS HAS NEVER been solved.

The use of other dasas is okay, but to jump from one to another to explain this or that event is, for me, suspect! I can accept that one dasa system explains health and death, another finances, yet another success in career, another marital or other relationships etc. Or that there is a dasa system that applies to all fields of life. But to has to search and find a different dasa to fit each event in the past, it has no value for the future, for one cannot say which will operate! To get back to the parallaxed moon: can you give me a couple of concrete examples in your life which fit the parallaxed Moon better? Please not with involved logic which will be beyond my meagre knowledge! You are still very young and live in England, not Yugoslavia or Central Africa, so that dire events are unlikely! Also please give me your DOB again: I somehow have two dates: 23 July and 24 july 1982! deep regards Mani Quote Link to comment Share on other sites More sharing options...

The situation is not affected in an extreme way until one actual goes way north, into the Arctic Circle or whatever. I personally feel that even there, the angles will be just as valid and sensitive as they are anywhere else. Unfortunately, very little research on charts based on those areas has been conducted to prove this. > > Ayanamsha, but this just seems to mess everything else up.

The words "mrtyu bhaga" translate to "death division". In each sign of the zodiac, each planet (and the Lagna and the Upagraha Mandi) have one particular spot as their Mrtyu Bhaga. So in Aries the Sun's MB is 20º. 20º Aries doesn't act as MB for any planet other than the Sun. All this becomes pretty clear if you see a table showing the MB's. As a rule of thumb (and this is debatable), any planet within a degree of it's MB point on either side, may be considered to be in Mrtyu Bhaga. In it's most basic sense, MB may be thought of as an affliction. However, it is quite a specific kind of affliction that appears to have a distinct importance in Medical Astrology, and longevity determination. This is where things start getting quite hazy, as a lot of research does need to be done. The Presence of the Lagna Lord, the Moon or the Atmakaraka in MB is considered to be particularly detrimental to the natives health as these planets are the personal planets of Jyotish. The Dasha of a planet in Mrtyu Bhaga, particularly if it rules the Lagna or the sixth or eighth etc., may cause accidents or health problems. If the planet in MB rules the house of another relative, the dasha of that planet may adversely affect the health of that relative. Needless to say, if these dashas occur simultaneously with malefic transits to the MB planet it makes problems a lot more likely. But you can experiment loads more! > To get back to the parallaxed moon: can you give me a couple of concrete > examples in your life which fit the parallaxed Moon better? OK. I'll stick just to the antardashas (or bhukti's) as these are what usually differ, and I'll stick just to the rasi. First my data: 24 July 1982 9:22 am BST Coventry, England Lagna = 19º30' Leo (Lahiri Ayanamsha) 1. Younger brother born on 22/03/1988. No Parallax = Mercury Bhukti - I don't see a thing With Parallax = Venus Bhukti - Venus is the third Lord, while associating with Rahu who is an exalted chara bhratrikaraka. 2. Completed GCSE's in June 1998. Excellent results came back on 27/08/1998. This officially ends compulsory British secondary education. No Parallax = Moon Dasha Venus Bhukti - You tell me! With Parallax = Mars Dasha Mars Bhukti - Mars is Yoga Karaka associated with the natural benefic and Lord of the fifth Jupiter. Mars, of course also rules the fourth house of secondary education. A couple of days later I began further education, which is kind of a middle stage between secondary and higher education. As Mars rules both houses of education, it don't matter where you allocate this in-between education - parallax still makes sense! 3. Had first car accident while learning (the other person's fault BTW!), on 31/05/2000 - No one hurt. No Parallax = Rahu Bhukti - Rahu is a karaka for sudden accidents Parallax = Jupiter Bhukti - Jupiter is the Lord of the eighth, associated with Mars, karaka for accidents. These are aspected by Rahu with his fifth aspect (if you accpet these). In this connection, I should mention that before I began Mars Jupiter I already did expect some kind of accident during this particular dasha, parallax worked in foresight as well. 4. Now I'm putting the following down as a whole, because particularly in August, I really did feel like the last summer holiday was very much "my time". Everything just went right!:- Began first part-time Job on 19/06/2000 Received excellent A-Level results on 19/08/2000. Passed Driving test on the 23/08/2000 (Janmashtami). Began first year of University, on 25/09/2000. In other words, I really did feel like Raja Yoga was happening, which Jupiter does participate in. Of course Jupiter does rule higher education, and associates with the Lord of the ninth, while this combination aspects the ninth. Again I must mention that I did expect at the beginning of this bhukti the last parts of it would be the ones to give me the results, because it was in a dusthana-upachaya. While things seemed very normal during most of it (mildly bad - dusthana), it was in the end (improvement - Upachaya) that I expected Raja Yoga type results. 5. In early December 2000, I found out I have some type of dorment Tuberculosis in me, and so began treatment. Without parallax - Rahu Bhukti With Parallax - Saturn Bhukti - Saturn Rules the sixth house of disease occupying the maraka second. I hope these explanation were simple enough. Of course one could expand on each of those points, and could find support in transits, vargas, and other dashas (I agree with your other point BTW). But I think even with simplicity parallax works better in my case. I'd love to hear your thoughts, Pursottam Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 23, 2001 Report Share Posted January 23, 2001 Dear Pursottam, Thanks for elucidation. I agree that you parallaxed moon seems better. But I am not sure that dasas and bukthis are applicable to the sort of events you have listed, for in general these last for relatively long periods, depending on which they are. I think the 3rd and 4th levels should be used to decide. It is at these levels that the subjective feeling of the person is strong and Shall pick up this later on, after I have done some study of the events - also other cases. regards Mani Quote Link to comment Share on other sites More sharing options...
