Clocciatti (Catolica U., Chile) and the Deep Lens Survey Team:\n\nWe have discovered a bursting optical source in\na B~22 mag anon galaxy.  The burst rose to maximum in less than ten\nminutes and faded by a factor of 20 in 12 minutes.  It is trans337\nat http://dls.bell-labs.com/transients.html\nPosition (J2000): 10 48 56.14  -05 00 41.1.\nImaging on this field over the last year shows no evidence of variable\nstar or variability associated with this galaxy.\nIt was detected at UT 2002 Jan 15 0707 UT rising above B=25 mag, peaked\nsometime within ten minutes later (600s B exposure at 0718 shows it\nat B=20.7 mag), and fell to B=23.8 mag in a 600s exposure at 0730.\nAnother image on UT 2002 Jan 16 shows it off.  These observations were\nmade using the Blanco 4m telescope at CTIO.  Spectra of the host taken\non the Magellan telescope on 2002-01-17 show a flat spectrum.\nAnalysis of this spectrum, and a VLA observation by D. Frail, are in\nprogress.  It is possible that this is a precursor to a GRB (see astro-ph/\n0108522).",
