  "body": "Luigi Piro, on behalf of the BeppoSAX team, reports:\n\nNote: we have decided to distribute this info to the BeppoSAX GRB alert\nlist due to the potential association of these events (or some of those)\nwith GRB.\n\nOn May 20 at 2:02:58 UT a fast X-ray transient, which we designate 1SAX\nJ0835.9+5118, was detected by one of the BeppoSAX WFC (n.1).  The event\nlasted about 10 s., with a peak flux of about 1 Crab in the 2-25 keV\nrange.  The position is (equinox 2000) R.A.=128.98, decl=51.31, with an\nerror radius of 3'.  No previously known X-ray source lies in the error\nbox.  At a preliminary analysis no simultaneous signal was detected by the\nGRBM (40-700 keV).  Follow up observations are encouraged to investigate\nthe nature of this object. \n\n\n\n[GCN OP NOTE: I am allowing this BeppoSAX Circular on a new x-ray transient\nto be distributed because (as pointed out) of the potential association\nof this type of event with GRBs.  I realize this is outside the scope\nof the Circulars in the strictess definition, but the potential is there\nand it seems a small price to pay at this point in time.  It also serves\nto explore this area for a future growth/expansion of the Circular service.\nAs always, I welcome comments from the community on the content and operations\nof the Circular service.\nCGRO-BATSE was in a \"triggers disabled\" mode (it was inside the N.American\nTrigger Disable Box) during SAX-WFC transient time.  The LAD high voltage\nwas on and the SAX RA,Dec location was visible (not earth occulted), so any\ndata and analysis will be delayed until tomorrow to determine if BATSE actually\ndetected this event or not.]",
