Max flash during the transition/phase shift period was at 02:56:34.9 UT on 20 Mar 99. Actual phase shift using previous methods may have been one half period later... but I assume the time listed is close enough. Obs location Falcon, CO USA using 7x50 binoculars Ron Lee For those unfamiliar..this is a geosynchronous satellite (actually supersynchronous) that flashes to naked eye magnitudes for a short period.
