Message-ID: <8955@scicom.AlphaCDC.COM> Date: 14 Dec 90 22:05:20 GMT Followup-To: sci.space Organization: Alpha Science Computer Networks, Denver, Co. Lines: 8 I have observed Cosmic Background Explorer twice this month in the early evening twilight. As it has moved from my zenith to the pole star the satellite varied in brightness from 0 mag to invisibility (+6) with a period of about 30 seconds. Has the mission concluded and the satellite uncontrolled or is sunlight hitting a flat panel and reflecting specularly?
