Bruce brought this error to my attention and I thought I'd better correct it for anyone else playing with my observations from the other night. In the list of altitudes I provided I substituted the calculated Hc for my observed Hs for the second Moon sight. Here, to correct my mistake and to provide the opportunity for anyone that wishes to correct my altitudes based on calculated Hc's I'll provide the observations again only more clearly. From a position of approximately 27-42.2N, 82-44.2W and a height of eye of about 10 feet. I took the following sights. Body Time Hs (corrected for IE) Calculated Hc Intercept Venus 00:11:41 7-50.6 7-40.7 0 Moon 00:12:48 44-52.6 45-41.3 to 1.2 Venus 00:13:27 7-25 7-17.3 away 2.5 Moon 00:14:02 44-36 45-25.6 to .5 Then the lunar distances, then these altitudes: Body Time Hs (corrected for IE) Calculated Hc Intercept Venus 00:16:36 6-43 6-35.5 away 3.4 Moon 00:17:31 43-51.6 44-41.1 to 1 Venus 00:18:09 6-24 6-15 away 2.2 Moon 00:19:09 43-30 44-20.3 to .5 ____________________Reply Separator____________________ Subject: Your Venus West Lunar Author: Stark4677@aol.com Date: 3/21/02 11:11 AM Chuck, I started to work your lunar and noticed something odd. The first two altitudes of the moon are increasing, and a few minutes later, the second two are decreasing. Calculated the apparent altitude of the moon's lower limb and decided the second of the first two altitudes should be 44? 25.'6, not 45? 25.'6. Check it out and, if you discover a mistake was made, you can post it yourself. Wish I had a dollar for every time I put down one number when I meant another, or just plain read a number wrong. I'll go ahead and work the observation and let you know what I get.
