MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Kislovodsk was pointed to the GRB130122A 28 sec s after
notice time and 91 sec after GRB time at 2013-01-22 23:45:40 UT in two
polarizations.
The weather conditions were not very good and continuosly deteriorated.
On our first (20s exposure) double set we marginally find an optical
transient at the Swift UVOT position (Lien et al., GCN 14140) with
unfiltered magnitude 16.8+-0.3 (m = 0.8R + 0.2B from USNO-B).
