Hi Jeremy, Mike Burkes again with my solutions of your Lunar as per Bruce Stark's Tables:
both Hc's are in agreement
corrected observation,D=40d 19.8m
my GMT per Lunar=08-13-26
true GMT              =08-08-40
difference              =00-04-46
My arc error          =2.7m

 

Interesting.  It was my first time with Frank's page and since my Starke tables are about 5,000 miles away, they aren't doing me much good.  My sight was certainly off, and there are probably a variety of reasons for it.

 

That was my first Sun/Moon lunar.  The five or six I have shot previously were with the Starke tables and all of them were using the traditional 3-sight method (Alt Moon, Alt Body, and LD) at twilight.  This was back in Jan or Feb 1999, so I don't even know if I still have them.  I might have stuck them in the book.  It is the only sight I rely on forms to reduce, all the rest I do from rote memory.  I seem to remember it took about an hour to do  the first one, and then went down from there as I learned the tables a bit better.  I also modified my tables by adding tabs so that I could find each individual table more easily.  When I get home and am bored, I will have to shoot some more.

It seems our errors in time are different. I may be missing something but was there a reason for the height of eye data?

 

I think it's habit, in retrospect, it makes no difference since we calculated the altitudes.
