Huge thanks, Ed!
This almost got me going.
Just one thing, you said:
Using your post data ...
D = 84° 35.2' - 82° 56.8'
= 1° 38.4'
Looking 1° 38.4' up in table ...
pLogD = 2766
and ...
d is total change in LD distance from First time (12:00) to your unknown time of lunar sight
d = 84° 35.2' - 83° 00.0'
= 1 35.2'
Looking 1 35.2' up in table ...
pLogd = 2623
In the prop.log table I use it is the other way around:
- 1° 38'.4 corresponds to prop.log 2623
- 1° 35'.2 corresponds to prop.log 2766
I think that was a typo (of your's).
And now I see why the resultin UTC ends in 09 seconds - I must furter interpolate between 02:54:06 and 02:54:12.
Thank you very much!
Warm regards,
Tony
PS
Where can I get the precomputed lunar distances (with prop.logs) for the 2016 and beyond? Mr Steven Wepster seems to abandon this project...
