TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1367 SUBJECT: GRB 020409, No Optical Detection to R = 22 DATE: 02/04/12 23:59:52 GMT FROM: Valery Petkov at Terskol Observatory A.Sergeev (IC AMER, Terskol), S.Karpov (BNO), V.Petkov (BNO), S.Barabanov (INASAN, Moskow), N.Karpov (IC AMER, Terskol) report: We have obtained R-band images of the error box of GRB 020409 (Piro 2002, GCN 1347) using the IC AMER 2m telescope at peak Terskol and MPAE two-channel focal reducer. Twelve 600s images were taken on 2002 April 10 at 19:33 UT. The second epoch three 600s images were taken on 2002 April. We find no evidence that any object in the BeppoSAX error box varies by more than approximately 0.5 mag The limiting magnitude of this search is approximately R = 22.
