We have imaged the field of Swift GRB 070917 with the 1.04m telescope at
NainiTal ~ 7.5 hours after the burst (Cummings et al. GCN 6791).
Observations were performed in R band (5*300 sec) in poor sky conditions.
We notice that the field is crowded and a considerable amount of
extinction (E(B - V) = 0.45 mag) is there in the burst direction. Visual
comparison with DSS-II plate does not show any new source within the
refined error-box (Tueller et al. GCN 6792). Photometry of the co-added
frame put a 3 sigma upper limit of ~20.5 mag in comparison to the nearby
USNO A2.0 star 0900-15768267 (R mag 16.6)
