Palazzi, Istituto Tecnologie e Studio Radiazioni Extraterrestri, Bologna, report: "The BeppoSAX Gamma Ray Burst Monitor was triggered on Mar. 26.888125 UT, coincident with BATSE trigger 6660. A quick-look analysis shows a single-peak gamma-ray burst lasting about 5 s and having a peak flux of 500 counts/s in the range 40-700 keV. The gamma-ray burst was also detected by unit 1 of the Wide Field Cameras (WFC1) with a peak flux of about 4 Crab in the range 2-26 keV. The position from a quick-look analysis is R.A. = 8h36m26s, Decl. = -18o53'.0 (equinox 2000.0). The accuracy of the satellite attitude was not optimum, and we adopt an error radius of 8'. Due to sun constraints, the GRB location cannot be presently observed by BeppoSAX Narrow Field Instruments."
