report:
Ulysses, Konus-Wind, and MO-HEND observed this burst at 56970 s.
As observed by Ulysses, it had a duration of approximately 20
seconds, a 25-100 keV fluence of approximately 8.3E-06 erg/cm2, and a
peak flux of approximately 6.9E-07 erg/cm2 s over 0.50 seconds.
We have triangulated it to two alternate preliminary 3 sigma error
boxes whose approximate areas are 200 sq. arcmin. each and whose
coordinates are:
RA(2000) DEC(2000)
ERROR BOX CENTER: 12 h 09 m 04.48 s 83 o 06 ' 44.26 "
ERROR BOX CORNER 1: 12 h 03 m 32.15 s 83 o 16 ' 13.61 "
ERROR BOX CORNER 2: 12 h 17 m 21.75 s 83 o 01 ' 37.33 "
ERROR BOX CORNER 3: 12 h 00 m 33.98 s 83 o 11 ' 12.68 "
ERROR BOX CORNER 4: 12 h 14 m 19.83 s 82 o 56 ' 58.10 "
ERROR BOX CENTER: 13 h 07 m 18.38 s 33 o 22 ' 54.25 "
ERROR BOX CORNER 5: 13 h 06 m 48.49 s 33 o 10 ' 44.30 "
ERROR BOX CORNER 6: 13 h 08 m 19.93 s 33 o 32 ' 11.73 "
ERROR BOX CORNER 7: 13 h 06 m 16.69 s 33 o 13 ' 39.21 "
ERROR BOX CORNER 8: 13 h 07 m 48.07 s 33 o 35 ' 05.69 "
These error boxes may be improved slightly, and we are seeking
auxiliary data which may allow us to distinguish between the two positions.
Maps will be posted shortly at sunspot.ssl.berkeley.edu/ipn3/020714.
