report:
 
At 22:24:54.5 UTC (80694.5 SOD) on 21 January 2006 the HETE FREGATE,
WXM, and SXC instruments detected event H4010, a bright short GRB.

Ground analysis of the SXC data yields a best-fit location

R.A. = +09h 09m 57s ; Dec. = +45d 40' 30" (J2000),

with a 90% confidence error radius of 80 arcseconds.

Further analyses are in progress.  Further information about this burst
