Abstract (from CDS):

Until recently the positions of gamma ray bursts were not sufficiently well known within a short timescale to localize and identify them with known celestial sources. Following the historical detection of the X-ray afterglow of the burst GRB 970228, extending from 30 s to 3 days after the main peak, by the Beppo-SAX satellite (Costa et al., 1997Natur.387..783C), and that of an optical transient ∼21hr after the burst (van Paradijs et al., 1997Natur.386..686V, hereafter VP )we report here the detection of the same optical transient, in images obtained ∼4.5hr hours earlier than in VP.
