R. M. Kippen (UAH/MSFC) reports on behalf of the BATSE GRB Team:
GRB000131 was detected by BATSE as trigger #7975 at 53877.497 s UT on
2000 January 31. BACODINE/GCN locations were not issued because the
trigger began in a real-time telemetry gap. The burst lasts more than
100 s and is therefore undoubtedly the same event detected by KONUS,
Ulysses and NEAR (GCN 529) some 76 s after the BATSE trigger time
(corresponding to the brightest pulse of the burst). The final BATSE
location is (R.A., Dec. J2000) = (94.0, -52.0 deg), with a total
(statistical + systematic) error radius of 2.3 deg (68% Conf.). This
location rules out one of the two possible IPN error boxes (GCN 529),
which means that the most probable combined BATSE+IPN error-box is:
RA(2000) DEC(2000)
ERROR BOX CENTER: 6 h 13 m 32.72 s -51 o 55 ' 36.77 "
ERROR BOX CORNER 1: 6 h 13 m 8.83 s -52 o 2 ' 20.83 "
ERROR BOX CORNER 2: 6 h 13 m 25.43 s -51 o 50 ' 11.43 "
ERROR BOX CORNER 3: 6 h 13 m 40.09 s -52 o 1 ' 1.94 "
ERROR BOX CORNER 4: 6 h 13 m 56.59 s -51 o 48 ' 52.07 "
The center of this box is within about 0.4 deg of the independent
BATSE location centroid.
