TITLE: GCN CIRCULAR NUMBER: 7961 SUBJECT: UVOT white band observations of GRB080710 DATE: 08/07/10 10:42:45 GMT FROM: Patricia Schady at MSSL/Swift P. Schady (MSSL-UCL) reports on behalf of the Swift/UVOT team: The UVOT began observing the field of GRB 080710 3138.2s after the BAT trigger. A single white band finding chart was downlinked promptly, and a bright, uncatalogued source with magnitude wh = 16.88+/-0.02 is detected at RA = 00:33:05.67 = 8.27363 Dec = +19:30:04.69 = 19.50130 with an uncertainty of 0.5 arcseconds (90% confidence), consistent with the XRT position (Sbarufatti et al., GCN 7958) and KAIT position (Chornock et al., GCN 7959). The value quoted above has not been corrected for the expected Galactic extinction corresponding to a reddening of E(B-V) = 0.08 mag in the direction of the burst (Schlegel et al. 1998).
