Probably out of control but they probably 'managed' to deorbit it. I can confirm your 'flash' observation of 92-83A last summer but I cannot say I didn't see it with other KH satellites. I remember an observation of 84-122A/15423 or KH11-6 which also showed some 'flash' behaviour which was more or less confirmed by Pierre Neirinck at that time. Tristan Cools tcools@nic.INbe.net
