    Hey Everyone,
         Late, as usual, but with the help of Kevin Fetter, I've tested and posted my Fall 2008 Geosat Flare calculator to his website at:
    (if you get a permissions or login box just click on "Cancel") At some point I will post a README.txt file to Kevin's site as well but for those of you who are familiar with this calculator it has gone through several seasons of testing with help of Greg Roberts (over 200 geosat eclipses! - Thanks Greg!) and deemed accurate (average error 1 min Right Ascension - probably because I assume the Sun is a point source vs. a half a degree extended object). When using this calculator, use negative numbers for western longitudes and southern latitudes. GMTO means GMT Offset. For instance, I'm using Central Daylight Time so that is GMT - 5hrs or -5 in the entry box.
         The geosat season is starting for those in the Northern Hemisphere and will intensify over the next few weeks - as evidenced by Kevin's observations. Unfortunately, in the second week of October when the season is peaking, the full Moon will be passing through the region. Be sure to to track the "Purple Dot" before and after eclipse to see the maximum chance of flaring. I will post more info when I get some more time!
