TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1357 SUBJECT: GRB 020409: Optical observations DATE: 02/04/11 09:21:06 GMT FROM: Eran Ofek at Tel Aviv U. E. O. Ofek, A. Gal-Yam, S. Kaspi, J. Dann, P. Ibbetson (Wise observatory, TAU) report: We have observed the error box of GRB 020409 (Piro, GCN 1347) using the Wise observatory 1m telescope equipped with the FOSC instrument. We obtained 4 exposures of 360 s in R-band on 2002 Apr 10.717 UTC, 20.0 hours after the burst. Comparison of the combined image with the POSS-II E plate reveals no candidate optical transients, to a limiting magnitude of R=19, within the 4' BeppoSAX error circle.
