eGreetz, Richard (and others).... I have your book, Richard... THX for the link and address to USNO... I have been hearing about the new UCAC 4 release for some time now, on the IOTAoccultations and MPML yahoo groups.... It is the latest and greatest update for calculating occultations, and chasing NEOs (asteroids). Works well with the Occult software from IOTA: http://www.lunar-occultations.com/iota/occult4.htm and Guide 9.0 from Project Pluto, by Bill Gray: http://www.projectpluto.com/ Taki's mag 8 star atlas (mentioned earlier) is useful, and free.

They are free for the asking (the Navy even pays for the stamps!). I have not yet installed them on my backup hard drive (will probably run about 25 gig), but programs like Guide and TheSky let you import data from such catalogs and plot them in the displays. That might even get you faint enough to challenge Chris Hanrahan or Paul Knauth! Log onto the USNO site (http://www.usno.navy.mil/USNO/astrometry/optical-IR-prod/ucac) and click the link to Brenda.hicks@xxxxxxxx and ask her for a set. Supply your mailing address, and you'll have them in about a week. Richard Harshaw Cave Creek, AZ "Remember: your mind works faster than you think." ------------ Ratz! Net Nanny got me again!!
