We observed error box of GRB070520 (Romano et al., GCN 6423) with AZT-11
(1.25m) and 1-m Zeiss (Simeiz) telescopes of CrAO in R-band on May 20 bet=
ween
(UT)19:50 and 22:00. No object is found in a refined XRT error box (Romano
et al., GCN 6427). Limiting magnitude of combined images is based on USNO
A2.0:
Mid time (UT), Exposure, R_Lim (3sigma), Telescope, Seeing
May 20.896 6x300 21.6 AZT-11 3.6"
May 20.835 53x60 22.4 1-m Zeiss 1.5"
