Due to a new h/w failure at IAS the BeppoSAX MAIL 19 & 20 have been delivered again to an old mailing list and from another server. We forward again the mails to the right list, apologizing for the delay. Giangiacomo Gandolfi on behalf of BeppoSAX Mission Scientist ---------------------------------------------------------------------------- BeppoSAX MAIL n. 99/19: GRB ALERT: GRB990712 Date: July 12, 19:17 UT On July 5, 16:43:02 UT a GRB (GRB990712) was detected simultaneously by the GRBM and WFC of BeppoSAX. Preliminary coordinates from WFC are: R.A.(2000)= 337.830 DEC(2000)= -73.346 The current error radius is of about 5' Due to Sun constraints BeppoSAX cannot perform a follow-on observation with the NFIs.
