Post-processing analysis of HETE data has revealed the presence of
GRB 050209, an untriggered GRB (=U11568) detected as HETE was
entering the SAA. The burst was detected at 01:31:41 UT and had a
duration of approximately 40 seconds. The GRB has been localized to
a circle of radius 7' (90% confidence) centered at:
RA = 08h 26m 09s, DEC = +19d 41m 02s (J2000).
Light curves in four spectral bands and a skymap for GRB 050209 are
provided at the following URL:
Because of the proximity of the SAA, extraction of spectral data
requires manual processing, and will be provided in a follow-up GCN
