Subject: [NavList 9782] Mercury
Lunar help
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
