Craig Markwardt writes: Here is a summary of the galactic bulge observations of 12 Oct 1999. The regularity of observations had been interrupted by other programs in the past few weeks. These scans are primarily east-west. * 4U 1728-34 is near its low, around 550 ct/s/5PCU (2-13 keV). Since the last observation, 4U 1820-30 has sharply increased, from ~900 ct/s to ~2600 ct/s. * GRS 1747-312 (= Terzan 6) is declining, but more slowly this time. The intensity is about 250 ct/s, compared to a maximum of 370 ct/s. * The rapid burster is also declining slowly, to a level of 1500 ct/s, compared to a maximum of 3000 ct/s. The last outburst had decayed to 20% of the maximum within a few days. * Whatever transient appeared in the galactic center (I called it Sgr A last time), has disapppeared. * Since it's large outburst, XTE J1819-254 (= SAX J1819...), has remained in a low state similar to its original low state before it became active (i.e., ~< 10 ct/s).
