TITLE: GCN CIRCULAR NUMBER: 17404 SUBJECT: GRB 150204A found in ground analysis of Swift-BAT data DATE: 15/02/04 18:11:41 GMT FROM: Jay R. Cummings at NASA/GSFC/Swift J. R. Cummings (CPI.com) on behalf of the Swift science team At 06:31:08, a GRB occurred during a preplanned Swift slew. This was the same event as Fermi GBM trigger 444724270. A mosaic of images from BAT photon event data revealed a bright source at RA, Dec 160.241, -64.043, which is: RA (J2000) 10h 40m 57.8s Dec (J2000) -64d 02' 34" with an estimated 90% uncertainty radius of 1.5 arcmin. The burst was a single symmetric cusp that lasted about 13 seconds. A Swift TOO has been requested.
