CD imaging of gamma ray burster fields

Abstract

Gamma Ray Bursts (GRBs) have been known for almost three decades. The nature of the objects producing these bursts is yet unknown and no counterparts have been identified in any other wavelength band so far except for GB970228 recently. In an attempt to identify the optical counterparts of GRBs we obtain deep CCD images of selected, strong GRB fields through broad band filters. From these images we expect to be able to identify any peculiar objects on the basis of photometric colours andlor variability. In this paper we present the preliminary results of the data obtained during our observing run in November 1996 at the UP State Observatory, Nainital.
