Craig Markwardt writes: This is a report on the "regular" scans of the galactic bulge, day 1902. There are no new bright sources, but I can mention some transient activity: * XTE J1819-254 has returned to its original high of about 280 ct/s (~28 mCrab). * XTE J1710-281, the new eclipser, has dropped again to ~10 ct/s, as has XTE J1744-36. * KS 1731, which I reported to have declined to its quiescent level in the previous scan (600 ct/s = 60 mCrab), has increased to 800 ct/s (~80 mCrab). * The Rapid Burster, MXB 1730-33, has declined from almost 3 Crab to 500-600 mCrab. * In the previous scan (day 1899) there was a new source detected at RA = 266.035 +/- 0.05; DEC = -23.122 +/- 0.05; FLUX about 30-40 ct/s (3-4 mCrab). Reflecting back, it was present since day 1892 (March 8). In today's scan the flux was seen to decrease slightly, indicating the source may have already peaked. * Another source is present in this scan near RA=260, DEC=-31.2 at a flux of about 1-2 mCrab. It is new this time. * The source in the galactic center, has begun to decrease. Is this SAX 1747? All fluxes 2-10 keV, count rates scaled to 5 PCUs. Craig
