Mazets,\non behalf of the KONUS and NEAR GRB teams, report:\n\nUlysses, KONUS-WIND, and NEAR observed a weak, ~20 s long gamma-ray\nburst on March 21, 1999, which was not observed by BATSE.  The\nEarth-crossing time for this event was 16012 s UT.  Triangulation\nresults in two positions, one of which may be eliminated due to the\ndirectional response of the two KONUS detectors.  (The eliminated\nposition is also consistent with no BATSE detection, as it is\nEarth-blocked for CGRO.)  The remaining error box is rather large\n(dimensions ~6'x40') due to the weakness of the burst.  The preliminary\nerror box corners are given below and the geometry may be viewed at\nhttp://ssl.berkeley.edu/ipn3/990321.  Some improvement is possible.\n\n   RA(2000)               DEC(2000)\n12 H 49 M 36.00 S      +80 D 05 M 59.72 S\n13 H 01 M 33.51 S      +79 D 37 M 25.99 S\n13 H 22 M 05.19 S      +79 D 03 M 18.34 S\n13 H 31 M 36.26 S      +78 D 30 M 29.37 S",
