GCN Circular 4018
E. O. Ofek, Y. M., Lipkin, J. Dann (Wise observatory, TAU) report: We have observed the Swift error box of GRB050922C (Norris et al. GCN 4013) using the Wise observatory 1m telescope starting at 2005, Sep 22nd, 22:10:56 UTC. We obtained a 210 sec unfiltered image (mid exposure time 0.0950 days after the Swift-BAT trigger) in which we detected the optical transient (OT) discovered by Rykoff et al. (GCN 4011). At that epoch, the OT magnitude was R~17.9, assuming R-mag=14.24 for the bright star 37 arcsec at PA=210deg from the OT.
