BeppoSAX MAIL n. 99/9: New fast X-ray transient

Note: we have decided to distribute this info to the BeppoSAX GRB alert
list due to the potential association of these events (or some of those)
with GRB.


On May 20 at 2:02:58 UT a fast X-ray transient, which we designate 1SAX
J0835.9+5118, was detected by one of the BeppoSAX WFC (n.1). The event
lasted about 10 s., with a peak flux of about 1 Crab in the 2-25 keV
range.  The position is (equinox 2000) R.A.=128.98, decl=51.31, with an
error radius of 3'. No previously known X-ray source lies in the error
box.  At a preliminary analysis no simultaneous signal was detected by the
GRBM (40-700 keV).  Follow up observations are encouraged to investigate
the nature of this object.
