Gandolfi, Istituto di Astrofisica Spaziale, CNR, \nRome, update the information given in GCN Circ. 427.: \"GRB 991014 was \nobserved with the Narrow Field Instruments on board BeppoSAX on two \noccasions: Oct. 15.4-16.4 UT (0.5-1.5 d after the burst) and Oct. \n24.8-25.9 (9.9-11.0 d after the burst). In the 2-10 keV images from both \nMedium-Energy Concentrator Spectrometer units 2 and 3, two sources only \n3' apart are within the combined WFC/IPN error regions of the burst (IAUC \n7281, GCN 419). Their positions are R.A. = 6h51m03s, Decl. = +11d36'05\" \n(SAX J0651.0+1136 = S1 in GCN 427; Eq. 2000.0; error radius 1.5') and \nR.A. = 6h50m57s, Decl. = +11d33'13\" (SAX J0651.0+1133 = S2 in GCN 427; \nerror radius 1'). The first source is not detected in the second \nobservation. The 3 sigma upper limit translates to a decay by at least a \nfactor of 2.2. The second source did not change significantly, the \nintensity change is 10+/-20%. Therefore, we identify SAX J0651.0+1136 as \nthe X-ray afterglow of GRB 991014.",
