GCN 4736, 4740) with repeat of unfiltered\n5-second exposures during the night of 11th February. The 1-sigma\nlimiting magnitude of images taken between 792 seconds before and 321\nseconds after the burst was around V=10.8 magnitude. The magnitude was\nderived by the Tycho-2 catalog. There was no significant emission from\nthe X-ray afterglow position up to the limiting magnitudes.\" \n\nThis message maybe cited.",
