Jeremy,
From the VSOP87 theory I get the following Mercury data:
Date UT GHA Declination
23 Aug 2009, 15:00:00 19 deg 45.7' S 0 deg 59.1'
23 Aug 2009, 16:00:00 34 deg 46.1' S 1 deg 00.4'
25 Aug 2009, 16:00:00 35 deg 07.4' S 2 deg 04.1'
25 Aug 2009, 17:00:00 50 deg 07.9' S 2 deg 05.3'
26 Aug 2009, 17:00:00 50 deg 22.6' S 2 deg 35.3'
26 Aug 2009, 18:00:00 65 deg 23.3' S 2 deg 36.5'

I am wondering if anyone on the list can help a poor sailor in need.
I went a bit crazy with the lunars this trip home and happened to shoot some of
this bright planet in the western sky. After a bit of research on
board, I discovered that it is probably Mercury. The trouble is
that the NA doesn't help with that planet.
In any case, i need the GHA (or SHA if you'd like) and Declination of
Mercury for the following times
1) 23 August 1500Z and 1600Z
2) 25 August 1600Z and 1700Z
3) 26 August 1700Z and 1800Z
I just need the data for each whole hour to plug into my spreadsheet.
Thanks for any and all help,
Jeremy
