Daniele, BeppoSAX SDC, Telespazio, Roma, and P. Giommi, BeppoSAX SDC, ASI, Rome. on behalf of the BeppoSAX Team report: "The BeppoSAX NFIs observed the region of GRB990705 (IAUC 7218) from Jul 6.142 (11 hours after the BeppoSAX GRBM+WFC trigger) to Jul 8.096 UT for a total MECS on source exposure time of 78 ksec. A preliminary analysis of the data shows a strong and variable contamination of the field by stray radiation coming from LMC X-2, which lies just outside the detector field of view (52 arcmin from the center). A more refined quick-look analysis detection reported in GCN #373.
