TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1118 SUBJECT: BeppoSAX ALERT: Possible X-ray rich GRB011030 DATE: 01/10/30 13:23:12 GMT FROM: Giangiacomo Gandolfi at IAS/CNR Frascati BeppoSAX ALERT: Possible X-ray rich GRB011030 On Oct. 30, 06:28:02 U.T. a faint transient has been detected by the WFC1 aboard BeppoSAX, without counterpart in the GRBM. Preliminary coordinates from WFC are: R.A.(2000)= 310.927 DEC.(2000)= 77.293 The error radius at this stage of analysis is 5'. A preliminary analysis of quick-look data shows that the event could be an X-ray rich GRB, but the low galactic latitude and the presence of a faint Rosat source (1RXS J204310.8+77172) inside the error box can not exclude the x-ray burster nature of the source. We are not planning a follow-up observation of this burst, due to the on-going testing phase of gyroless attitude control system.

Apologies for the delay.] [GCN OPS NOTE: Due to confusion about active submitors accounts and delays in the distributions, this was submitted twice and distributed twice. The second copy (originally numbered 1119) was deleted from the archive and the serial number sequence set back to waiting for the next submission.]
