TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4527 SUBJECT: GRB 060116: Swift/UVOT upper limits DATE: 06/01/16 17:24:21 GMT FROM: Tracey Poole at MSSL T. S. Poole (UCL-MSSL), S. Campana (INAF-OAB), J. Nousek (PSU), N. White (GSFC), N. Gehrels (GSFC) on behalf of the Swift/UVOT team. The Swift/UVOT began observing the field of GRB060116 (BAT Trigger=177533, S. Campana, et. al, GCN 4519) at 08:39:46, 154s after the BAT trigger. No new source is detected at the XRT position (S. Campana, GCN 4522) in coadded images with any of the filters. The following 3-sigma magnitude upper limits are not corrected for Galactic extinction; E(B-V) = 0.264. Filter T_range(s) T_exp(s) 3sigma(mag) V 154-610 219.6 19.2 B 361-706 219.6 20.2 W1 639-802 39.6 18.5 M2 614-778 38.6 18.5 W2 567-731 39.6 18.5 Where T_range is time post-trigger, and T_exp is the exposure time of the observation. A 6 arcsec radius was used for all filters. This message may be cited.
