We have observed the field of the INTEGRAL GRB 100331A
(Mereghetti et al. GCN 10555) using the 0.6 Yock-Allen robotic
telescope (BOOTES-3) located in Blenheim, New Zealand starting
at 07:12 UT (6.7 hours after the burst). In a 35x60s combined exposure
with clear filter, obtained under non optimal conditions, we do not
detect any new source within the full INTEGRAL error circle down to a
3-sigma limiting magnitude of R~17.8. Further analysis is ongoing.
