TITLE: GCN GRB OBSERVATION REPORT NUMBER: 427 SUBJECT: GRB 991014 - BeppoSAX NFI observations DATE: 99/10/22 16:32:48 GMT FROM: Jean in't Zand at SRON J. in 't Zand and L. Kuiper, Space Research Organization Netherlands, Utrecht; L.A. Antonelli, Osservatorio Astronomico di Roma; A. Coletta, S. Rebecchi, M. Stornelli, M. Capalbi, BeppoSAX Science Operations Center, Telespazio, Rome; and G. Gandolfi, Istituto di Astrofisica Spaziale, CNR, Rome, report: "GRB 991014 was observed with the Narrow Field Instruments (NFI) on board BeppoSAX from Oct. 15.4 to 16.4 UT (starting 13.0 hrs after the burst trigger time). In the 2-10 keV image of all data from both Medium-Energy Concentrator Spectrometer units 2 and 3, two point sources are apparent within the WFC/IPN combined error box (Tassone et al., IAUC 7281, Hurley et al. GCN 419). Their positions are R.A. = 6h51m03s, Decl. = +11d36'05" (S1) and R.A. = 6h50m59s, Decl. = +11d33'09" (S2, Eq. 2000.0). The error radius for both sources is 1'.5. Neither S1 nor S2 show conclusive evidence of decay, but this is a statistical issue rather than a meaningful statement about the decay index. To search for a decay and possibly identify the afterglow with S1 or S2, another NFI pointing is scheduled for Oct. 24.
