GCN 10438) \nwith AZT-11 telescope of CrAO starting (UT) Feb. 19  22:54 (7.6 hours after \nburst onset). We detect the galaxy (previously reported by Holland & \nRowlinson (GCN 10436),  Bloom & Nugent (GCN 10437)). The coordinates of the \ngalaxy are (J2000) RA= 10 16 48.61, Dec= -12 33 57.15 (with uncertainties \n0.5 arcsec in both coordinates). We do not detect optical afterglow \n(Jakobsson et al. GCN 10430, Kruehler et al. GCN 10439). The photometry is \nbased on USNO-B1.0 star   0774-0276292   (assuming R=16.90):\n\nT0+      Filter,   Exposure,  mag.
