The 1-sigma limiting magnitude of images taken between 792 seconds before and 321 seconds after the burst was around V=10.8 magnitude. The magnitude was derived by the Tycho-2 catalog. There was no significant emission from the X-ray afterglow position up to the limiting magnitudes." This message maybe cited.
