>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 :-)

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).
 
Greetings,
