TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1384 SUBJECT: GRB020427 BeppoSAX NFI Observation DATE: 02/04/29 10:38:42 GMT FROM: Giangiacomo Gandolfi at IAS/CNR Frascati GRB020427 BeppoSAX NFI observation A short BeppoSAX TOO observation of GB020427 has been carried on about 13 hours after the GRB. A preliminary analysis of MECS (1.6-10 keV) image shows two unknown and faint sources in the WFC error circle, contaminating each other. A more refined analysis is required to desentangle the couple and to confirm the possible fading of one of the objects. A second (and final) BeppoSAX observation is planned this evening. No NFI position is available at the moment due to the bad contamination of the objects. Further follow-up observations are encouraged.
