Description
Summary:Preliminary results of an examination of the Ondrejov and Sonneberg plate collections for possible optical counterparts to gamma-ray bursters are presented. The investigation proceeds in three different directions: (1) time-correlated searches for gamma-ray bursts (GRB) with known positions, (2) time-correlated searches for GRB without know positions, and (3) archival searches. 3 GRB with known positions and 28 GRB without known positions were studied in this way; archival searches representing a total exposure of 2.75 yr were done for 10 GRB positions, with limiting magnitudes for a 1 s flash between 3 and 8. No evidence for true optical images associated with GRB was found. Some statistical conclusions are drawn and the results obtained are discussed.
