follow up collaboration report:
We observed the error box of GRB080307 (Holland et al. GCN 7362) on March
05 with SR-22 telescope of UAFO observatory. A set of 20 unfiltered images
of 60 s exposure was obtained starting (UT) 11:36:55, i.e. 13.5 minutes
after burst onset. No new object is detected within enhanced XRT error
circle (Goad et al. GCN 7366). Based on USNO-A2.0 (R) we estimated upper
limit as following
T0+ Exposure UL
(mid)
23.5 m 10x60 s 18.8
