BeppoSAX MAIL n. 99/18: GRB990705: possible X-ray afterglow A BeppoSAX follow-up of GRB990705 started about 11 hr after the burst. A quick look analysis of the first five orbits of the MECS data at SOC shows only one object, previously unknown, inside the refined error circle of the WFC and located near the edge of the LMC. Preliminary coordinates are: R.A.(2000)= 77.489 DEC(2000)= -72.132 The error radius is 2' BeppoSAX will continue its observation and monitoring of this source up to a total observing time of 100 ksec.
