GRB 970815 #001 D. A. Smith, A. M. Levine, E. H. Morgan, and A. Wood report, on behalf of the RXTE/ASM team at the Massachusetts Institute of Technology and Goddard Space Flight Center, their independent detection with the ASM detector of an x-ray burst that they identify as a counterpart to the gamma-ray burst source detected by the Compton Gamma Ray Observatory's BATSE detector on Aug. 15.50491 UT (posted at http://lheawww.gsfc.nasa.gov/docs/gamcosray/legr/ bacodine/baco_notes.html): "The burst rise was detected in one camera on Aug. 15.50597. At Aug. 15.50623, the cameras were rotated through 6 deg, such that the burst came into the field-of- view of a second camera. Observations with two cameras at different orientations enabled us to estimate the position of the burst source to be within an error box having the following corners: R.A. = 16h06m36s, Decl. = +81o27'36"; 16h10m50s, +81o33'36"; 16h08m10s, +81o31'12"; 16h09m17s, +81o30'00" (equinox 2000.0). The burst lasted about 130 s and showed a double-peaked structure, reaching a maximum intensity of almost 2 Crab (2-12 keV) in the second peak."
