Optical counterparts for the gamma-ray bursts: two more probable optical transients and estimates of the occurrence rate.
Abstract
The authors describe the results of an extensive search for optical flashes at the archival astrographic plate collection and meteor patrol camera films of Odessa, Kiev and Dushanbe observatories. The upper limits of (6 - 8)×10-4h-1sr-1 for the event rates of flashes brighter than 6m - 8m with the 95% confidence level is derived from the meteor patrol data. Two "new" objects have been discovered at the Odessa plates inside the GB 790514 and GB 791215 error boxes.
