(Kanazawa Univerasity) report on behalf of the Kanazawa GRB team
The robotic Kanazawa 0.4-m telescope imaged the field of GRB 071011
(Marshall et al. GCN 6882) at 190 seconds after the burst trigger.
We observed the field in unfiltered 10x 30s exposure.
Based on comparison of our initial image with the DSS plate, we do
not detect any source inside the XRT error circle (Sbarufatti et al.
; GCN 6891, Swan et al. 6894), and also we do not detect the source
reported by Cenko (GCN 6895) . Our upper limit is ~17.6 under the poor
sky condition.
