Several BVRI Bessel images were obtained on May 3, and 5 under good photometric and seeing conditions (1-1.5 arcsec). Based on filed photometry by A. Henden (GCN 2082) we estimate the OT magnitudes: Mid time exposure filter mag err UT, May. sec 03.700 2400 B 22.14 0.13 03.726 1800 V 21.29 0.10 03.670 1800 R 20.87 0.09 03.750 1800 I 20.08 0.12 05.690 3000 B 22.08 0.11 05.722 1800 V 21.33 0.08 05.655 1800 R 20.74 0.10 05.746 1800 I 20.28 0.15 Multicolor observations will be continued.
