To the professionals out there.
I have the target and sun parameters sorted - but am battling with the moon calculations.
The algorithms are based on www.stjarnhimlen.se/comp/ppcomp.html and www.stjarnhimlen.se/comp/tutorial.html.
The calculation results correspond with the tutorial and even with Skytools 3, but not with other tools and almanacs.
For instance for my location 33 59 20 S and 25 31 49 E for today I get
Rise: 19:01 Transit: 01:12 Set: 07:25
Skytools:
Rise: 19:10 Transit: 01:16 Set: 07:27
TheSkyX and others
Rise: 19:07 Transit: 00:34 Set: 06:37
So obviously Skytools and I have got it wrong.
So, can anyone help me with the correct algorithm (to calculate the moon's alt/az for a particular time and location.)
Would be much appreciated.
