Hi Morco This flare was predicted but I thought it would be quite faint and perhaps too low for you to observe. Here is the full latest list of predictions for you location. There are no more after 30/05/06. Flare Results for Observer Lat=52.16 Long=4.49 Satellite NORAD 28646 Flare Results for Flight Mode YVV Panel Angle 33° 2.

SAR MA 9.16545060435455 at 29/05/2006 21:48:50 Alt=28.4380149814017 Number 3 is the flare you saw last night. So the prediction based on this panel angle of 33 degrees is 13 seconds early. If on the other hand the panel angle was 27 degrees we get Flare Results for Observer Lat=52.16 Long=4.49 Satellite NORAD 28646 Flare Results for Flight Mode YVV Panel Angle 27° 5. SAR MA 0.637288104773435 at 25/05/2006 22:02:21 Alt=37.2799747652266 This time the timing is exact and the mis-angle (angle btween the reflected light and a line from you to the satellite) is a much more reasonable 0.63 degrees. So now we have seen 4 flares for Lacrosse 5 which have suggested panel angles of 35, 30, 36 an 27 degrees. I have a potentially good one tonight so I hope it's clear.
