First, I have a set of observations from last night that I'm hoping you might have a look at George, and see if it looks like I'm still headed in the right direction. From approximately 27-42.0 N, 82-44.2 W I took a set of observation as follows: (All times GMT 19 March followed by altitudes Degree-Minutes) Venus 00:11:41 7-50.6 Moon 00:12:48 44-52.6 Venus 00:14:02 7-25 Moon 00:14:02 45-25.6 Lunar Distances 00:14:59 37-43.4 00:15:27 37-43.2 00:16:01 37-43.0 Venus 00:16:36 6-43 Moon 00:17:31 43-51.6 Venus 00:18:09 6-24 Moon 00:19:09 43-30 I roughly averaged the sights and used the following for my calculations: Venus 7-5.6 Moon 44-12.5 Distance between 37-43.2 From which I calculated: B .69733 P 38.43635 R 6.65151 d 37.97333 D 38.72479 SD 15.1995 HP 55.1 D1 (00:00:00) 38.58036 D2 (01:00:00) 39.03829 T 00:18:55 v. real time of observation of 00:15:29 So, based on the fact that the Moon was rather high and, by my observations, was moving at an apparent speed of about 24 arc minutes an hour can I assume that some of my error is due to "parallactic retardation"? Or, did I make some more basic mistake? One other question from Part 4, how do Bruce's tables compare to the tables that used to be in Bowditch?
