report on behalf of a larger collaboration:
We observed the field of GRB 100526A (Vetere et al., GCN 10797) with
the NOT equipped with ALFOSC in the R and i filters. Observations
started on May 26 at 22:43 and 23:10 UT in R and i, respectively (6.282
and 6.742 hr after the GRB), and were affected by the closeby Moon (47
deg away).
We do not detect any new object within the refined XRT error circle
(Beardmore et al, GCN 10800) in both R and i bands. The limiting
magnitude is R(Vega) ~ 23.8, calibrated against the SDSS catalog.
