Craig Markwardt writes: Here is a report of new developments of the scans of the galactic bulge. First a general status report concerning activity since my last report. * SLX 1735-269, which had been about 100 ct/s, had a flare to 250 ct/s around 27 Apr, then declined to essentially zero, all in the space of two weeks. * Within the past week GRS 1747-312 = TERZAN 6 = R 1747-314 has increase from about 10 to 350 ct/s. A TOO observation yesterday showed that the flux was about 450 ct/s. No high frequency variability was detected -- only red noise below ~ 0.5 Hz. * XTE J1723-376 and 4U 1711-34 have both become largely inactive. 4U * 1820-30 continues to be near its peak flux of 4000 ct/s/5PCU (~400 mCrab) * XTE J1710-281 continues to be highly variable, as does XTE J1819-254. Regarding the scans of today, May 13 (Day 1958) * KS 1731-260 has flared again, to near the same flux (~1600 ct/s) as its previous outburst. * GRS 1747-312 is now at 350 ct/s again. Considering the flux from yesterday, it may have already peaked and begun declining. Craig
