Craig Markwardt writes: Here is a summary of the observations of the galactic bulge. This scan was a "regular" scan (primarily in DEC). * The Terzan 6 source GRS 1747-312 continues to be bright, and apparently is not decaying monotonically. Count rate is about 300 ct/s/5PCU, the same as last time (5 days ago). * SLX 1735-269, which turned on again in the last observation after being off for about two weeks, continues to increase and is now at 300 ct/s. Its persistent level before the turn-off was about 100 ct/s. * KS 1731-260 continues to be bright, at about 1500 ct/s * 4U 1820-30 has declined significantly in the past week. While it was at 4000 ct/s last week, its intensity is about 2200 ct/s now. Craig
