Abstract

We have examined 8004 plates at the Harvard College Observatory Plate Collection searching for optical transient emission from the gamma-ray burst GRB 970228. This is the first archival search carried out so far for a gamma-ray burst with known transient optical emission. The total exposure time amounts to yr. No convincing optical activity was found above 12.5 mag at the expected position of the GRB 970228 optical counterpart.

Key words: gamma rays: bursts
