(IKI) report on behalf of larger GRB follow-up collaboration:
We observed the field of GRB 150607A (Swift trigger 642620, D'Elia et
al., GCN 17904) with the AS-32 (0.7m) telescope of Abastumani
Observatory (AAO) starting on June, 07 17:54:22, and with AZT-8
telescope of CrAO starting on June, 07 19:43:21. The afterglow of GRB
150607A (Kruehler et al., GCN 17908; Hagen et al., GCN 17909) is clearly
detected in early observation in AAO. Preliminary photometry is following.
