TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3677 SUBJECT: RXTE ASM Detection of GRB050724 DATE: 05/07/25 22:55:57 GMT FROM: Ron Remilard at MIT Ron Remillard (MIT), Jean Swank (GSFC), and Alan Levine (MIT) report for the RXTE/ASM team at MIT and NASA/GSFC The RXTE All-Sky Monitor detected GRB050724 in a single camera (SSC 2) with a significance of 9.5 sigma. The event duration is 2.0 (0.5) s, and the burst (integrated) is detected in each of the 3 standard ASM energy bands: 1.5-3, 3-5, and 5-12 keV. When plotted at 32 ms time resolution, the instantaneous maximum is 10.8 (3.0) Crab. Despite weak statistics, the burst profile appears to show two peaks, as reported in GCN Circular 3667, and both peaks are stronger at 5-12 keV, compared to 2-5 keV (see http://xte.mit.edu/~rr/grb050724_32ms.ps).
