behalf of larger GRB follow-up collaboration:
We observed the field of the Swift GRB 130420A (Page et al., GCN 14406)
with 0.45-m telescope of ISON-NM observatory on Apr. 20, between (UT)
07:30:54 - 10:51:49. The observation started automatically 144 s after
burst trigger. We took several unfiltered images of 30, 60 and 300 s
exposures. The optical counterpart of GRB 130418A (Guidorzi et al., GCN
14405; Page et al., GCN 14406; Guver et al., GCN 14407) is clearly visible
in single images.
Coordinates of the counterpart are (J2000) RA = 13:04:25.56 Dec =
+59:25:26.8 with uncertainties of 0.2" coincide with the coordinates
reported early (Guidorzi et al., GCN 14405
