Abstract Preliminary results of an investigation of astronomical plates from Ondřejov, Sonneberg and Bamberg observatories archives for optical transients related to the gamma ray burst phenomena are presented. Besides of archival searches representing 6.5 years of monitoring, the time-correlated optical studies were done for 9 gamma ray burst sources (GRBS) with known and for 29 GRBS without known position. Only one optical transient appearing on more than one plate was found, the estimated gamma-ray to optical V fluency ratio being ∼ 300 for 1 sec flash.
