We observed the field of the Swift GRB 100614A (Stratta  et al. GCN 10837)
with AZT-11 telescope of  CrAO between (UT) June, 15  19:18 -- 20:19.
We do not detect any source in enhanced XRT error circle (Osborne et al.,
GCN 10849).
The photometry based on USNO-B1.0 star 1392-0274963 (RA(J2000) = 17:34:02.22
Dec(J2000)= +49:14:58.3 )  assuming  R=17.73  is following:

T0+      Filter,   Exposure,  mag. UL
(mid, d)              (s)

0.9236     R       20x180    > 21.9
