TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3879 SUBJECT: Swift-BAT trigger 152038 is probably not a GRB DATE: 05/08/25 18:05:50 GMT FROM: Scott Barthelmy at NASA/GSFC S. Barthelmy (GSFC), J. Cummings (GSFC/NRC), C. Markwardt (GSFC/UMD) on behalf of the Swift-BAT team: The Swift-BAT triggered (trigger=152038) at 17:43:37 UT on 25 August 2005. Using only the TDRSS data products (rough lightcurve and image detection significance), we can not say if this is real or not; although the tentative idenitification is not a real GRB (2-to-1 confidence level). We will know more in about an hour when the full data set is downlinked.
