  K. Hurley, on behalf of the Ulysses GRB team, T. Cline, on behalf of the Konus-Wind and NEAR GRB teams, and E. Mazets, and S. Golenetskii, on behalf of the KONUS-WIND GRB team, report:
  Ulysses, NEAR, and KONUS-WIND observed this GRB at 58275 seconds. As observed by Ulysses, it had a duration of approximately 10. seconds, a 25-100 keV fluence of approximately 7.8E-07 erg/cm2, and a peak flux of approximately 5.7E-07 erg/cm2 s over .25 seconds
  We have triangulated it to a preliminary, 3 sigma error box with approximate area 375. sq. arcmin. whose coordinates are:

   ERROR BOX CENTER:    8 h  3 m 46.52 s    -16 o  7 '  24.09 " 
   ERROR BOX CORNER 1:  8 h  3 m 26.07 s    -16 o  1 '  26.37 " 
   ERROR BOX CORNER 2:  8 h  5 m 35.32 s    -16 o  1 '    .33 " 
   ERROR BOX CORNER 3:  8 h  1 m 58.85 s    -16 o 13 '  44.83 " 
   ERROR BOX CORNER 4:  8 h  4 m  7.00 s    -16 o 13 '  21.71 " 
  

  This error box may be improved.

• GCN notice #911
  B. Dillon and J. Dellinger, FBAC, as part of the AAVSO monitoring group, report:
  Images covering 95percent of the error box for GRB010103 were taken with the 0.45m Ft. Bend telescope and AP8 CCD; only the extreme eastern and western corners were missed. Data from 010105 and 010106 UT were blinked, and no new object was present on the unfiltered images to a limiting magnitude of approximately R=19.2. The images can be found at http://www.geocities.com/amicustellarum/grb/grb010103.html
