TITLE: GCN CIRCULAR NUMBER: 4746 SUBJECT: GRB060210: Swift/UVOT Upper Limits DATE: 06/02/11 23:29:28 GMT FROM: Peter Brown at PSU P. J. Brown (PSU), A. Beardmore (U Leicester), P. Schady (PSU/UCL-MSSL), N. Gehrels (GSFC) on behalf of the Swift/UVOT team report: The Swift/UVOT began taking data on the field of GRB 060210 at 05:00:28 UT on 2006-02-10, approximately 98 s after the BAT trigger (Beardmore et al., GCN 4724). No source is detected in the refined XRT error circle (Beardmore et al., GCN 4733) or at the position of the afterglow identified by Fox & Cenko (GCN 4723) in either the 200s finding chart images or summed images down to the following 3-sigma magnitude upper limits: Filter T_range(s) Exp(s) 3sigUL(mag) V 98-297 200 18.9 V 98-17151 1574 20.1 B 305-504 200 19.9 B 305-28728 2557 21.3 U 3750-27815 1594 20.6 UVW1 606-12060 1289 20.8 UVM2 582-17970 1402 21.1 UVW2 535-23754 2231 21.5 White 510-29539 2170 21.4 These magnitudes are uncorrected for Galactic extinction; E(B-V) = 0.09. These non-detections are consistent with the spectrum described by Cucchiara, Fox & Berger (GCN 4729)
