>From October 12th the flares are predicted with Randy John's program and later with Rob Matson's. Both are very accurate. It's nice that the magnitude estimates of Iridflar are mostly pessimistic. For example the second flare of October 18th was predicted as +1.0. We showed it at a meeting of our local astronomy club and it turned out to be -6 :-) NORAD date time Dir aI eI aM eM aS eS Phs Dur Mag Obs COSPAR xxxxx dd-mm-yy hh:mm:ss x xxx xx xxx xx xxx xx xxx tt Sn III yy-nn 24842 22-09-97 18:49:00 S 143 25 xxx xx xxx -xx xxx 26 -2 BD 97-30G 24838 23-09-97 18:45:55 S 153 24 xxx xx xxx -xx xxx xx -2 BD 97-30C 24839 23-09-97 18:52:20 S 120 53 xxx xx xxx -xx xxx xx +2 BD 97-30D 24838 26-09-97 18:43:51 S 157 32 xxx xx xxx -xx xxx xx -3 BD 97-30C 24837 04-10-97 18:03:xx S xxx xx xxx xx xxx -xx xxx xx 0 BD2 97-30B 24869 12-10-97 08:08:xx N 143 80 xxx xx xxx +17 xxx 1 -7 BD 97-34A 24841 14-10-97 05:53:43 N 11 59 xxx xx xxx -2 xxx 4 -8 CD 97-30F 24838 17-10-97 17:04:47 S 181 48 xxx xx xxx -4 xxx 5 -2 BD 97-30C 24839 17-10-97 17:13:39 S 190 47 xxx xx xxx -5 xxx 6 -2 CD2 97-30D 24869 18-10-97 18:34:00 S 125 44 xxx xx xxx -19 xxx xx +1 BCD 97-34A 24871 18-10-97 18:43:03 S 134 51 xxx xx xxx -20 xxx xx -6 BCD 97-34C 24873 19-10-97 18:46:52 S 197 83 xxx xx xxx -xx xxx xx +1 BD 97-34E 24870 21-10-97 18:25:01 S 137 48 xxx xx xxx -18 xxx xx -7 BCD 97-34B 24872 22-10-97 18:19:01 S 137 47 xxx xx xxx -18 xxx xx 0 BCD 97-34D 24839 23-10-97 05:08:59 N 2 45 xxx xx xxx -11 xxx 26 -2 BD 97-30D 24871 23-10-97 07:11:04 N 11 82 xxx xx xxx +7 xxx 3 -8 CD 97-34C BD = Bram Dorreman CD = Chris Dorreman BCD = both BD2 = BD in Retie (51d16'N 05d04'E) CD2 = CD in Mechelen (51d02'N 04d29'E) Note that there are two daylight observations. Even when the Sun is above the horizon, the flares are easy to detect (if you know where to look).
