Moon's wobble

[Guest guest]

Dear Group,

 

Apologies! I pasted in a couple of items on my last post, not

realising that the final paragraph of the second item seemed to

be a comment that I was appending. Let me clarify the context

and apologise for any misleading impressions.

 

Some time ago I was doing a little bit of research on the

differences between mean node and true node calculations. My

understanding is that in Indian astrology we use mean node

calculations. Some people may prefer to use true node

calculations and Lahiri's includes them, but I haven't personally

come across anyone who advocates their use.

 

Nevertheless, I wanted to know a bit more about 'true nodes'

because their 'behaviour' over a six month period is curious. A

Google inquiry led me to the site mentioned at the head of the

second item. That item was one of the closing entries on that

site.

 

It seems that around 1999, some European western astrologers

were debating a 'Black Moon'. (I don't personally know what this

is and it didn't seem to be relevant to Indian astrology.) Their

lengthy discussion included a few posts on the calculation of the

'true node' - virtually the only explanations I tracked down. (Also,

let's be honest - my grasp of astronomical calculations is

minimal!) My mental summary on the subject was that the calc's

for the 'true node' have only come into existence within the last

few decades. Even then, I think (recollect) that there may be

some other factors which render them less than entirely reliable.

 

At this point I didn't pursue the subject any further, since the

infancy of the 'true node' calc's seemed to confirm the benefits of

sticking with the mean node calc's.

 

Once again, my apologies for any confusion caused.

 

Cheers, Kriya
