Coletta, Scientific Operation Centre, Telespazio, Roma, L.A. Antonelli, Osservatorio Astronomico di Roma, Roma, M.J.S. Smith, J. in 't Zand, Space Research Organization Netherlands (SRON), Utrecht, C. Guidorzi, Universita' di Ferrara, Ferrara, M. Feroci IAS/CNR, Roma, report: "The BeppoSAX Gamma Ray Burst Monitor (GRBM) and Wide Field Camera (WFC unit 1) observed a gamma-ray burst on February 14.042 UT. A preliminary analysis reveals a duration of about 9 s in the GRBM, with a peak photon countrate of 4.2E3 cts/s in the 40-700 keV energy band. In the WFC, the duration is about 115 s and the peak flux is 2.9 Crab (2-26 keV). The position of the X-ray counterpart is R.A.= 18h 4m 18s Decl.= -66 26'.3" (equinox 2000.0) with a 99% error radius of 6.5'. An NFI follow-up is being carried on." This message is citable.
