TITLE: GCN GRB OBSERVATION REPORT NUMBER: 174 SUBJECT: GRB981226, BeppoSAX Christmas GRB DATE: 98/12/28 05:03:57 GMT FROM: Luigi Piro at IAS/CNR Frascati L. Piro and the BeppoSAX team report: A GRB (GB981226) was detected by the GRBM and WFC of BeppoSAX on Dec.26, around 9:47 U.T. Preliminary coordinates from WFC are: R.A.(2000)=352.433 DEC(2000)=-23.942 The error radius is about 8', including a systematic error due a less-than-optimal attitude configuration. A follow-on with NFI is being planned. [GCN OP NOTE: This Circular was received 26 Dec 1998 15:00 UT. However, it was not sent to the automated system, and I was away on holiday without any computer access to catch it sitting in my inbox. I am distributing it for the record even though most of the community knows of this burst, and several have made follow-up observations: GCN Circulars 169, 172, and 173. I will attempt to correct such shortcomings plus the GCN Notice format problem for future events.]
