BeppoSAX MAIL n. 99/14: GRB990704: possible X-ray afterglow A BeppoSAX follow-up of GRB990704 started about 8 hr after the burst. Preliminary analysis of the first three orbits of the MECS data at SOC shows a previously unknown source inside the WFC error circle. Preliminary coordinates are: RA(2000)= 184.872 DEC(2000)= -3.840 The error radius is 1.7' BeppoSAX is continuing its observation.
