V616 Monocerotis (A0620-00)
T. Matilsky, Massachusetts Institute of Technology, reports that the SAS-3 Group has observed evidence for a 7d.8 +/- 0d.7 periodicity in the 1.3-5 keV flux of A0620-00. The 150 data points are spaced at approximately equal intervals over 32 days beginning Jan. 7, when the source brightness was 0.2 that of the Crab. The 50-percent-amplitude modulation is approximately sinusoidal, with the first minimum occurring on Jan. 14.
