We report photometry of our observation (GCN 17468) of the field of the
Swift GRB 150213B (Pagani et al., GCN 17464) with AS-32 (0.7m) telescope
of Abastumani Observatory. The optical afterglow (Pagani et al., GCN
17464; Kann et al., GCN 17465; Malesani et al., GCN 17467) is visible on
single images. The photometry of the afterglow is following

The photometry might be affected by the presence of the nearby bright
star (e.g., Kann et al., GCN 17465). The photometry is based on nearby
SDSS DR9 stars:
