Boer, J-F Olive, and J-P Dezalay, on behalf of the HETE GRB team, report:
  Ulysses, Mars Odyssey-GRS, HETE-FREGATE, INTEGRAL (SPI-ACS), and Konus-Wind observed this GRB at 27277 seconds. As observed by Ulysses, it had a duration of approximately 15 seconds, a 25-100 keV fluence of approximately 2.3E-06 erg/cm2, and a peak flux of approximately 4.7E-07 erg/cm2 s over 0.25 seconds.
  We have triangulated it to a preliminary, 3 sigma error box whose approximate area is 314. sq. arcmin. and whose coordinates are:

      RA(2000)                              DEC(2000)

  This error box may be improved.
• GCN notice #2137
  J. Schaefer, D. Gibbs, M. Nysewander, R. Canterna, and D. Reichart report on behalf of the FUN GRB collaboration:
  We imaged the entire 314 sq arcmin error box of the IPN burst, GRB 030413 (Hurley et al. GCN 2135) with the UWYO 0.6m Red Buttes Observatory (RBO) Telescope beginning 21.701 hours after the burst (April 14.2199 UT). We integrated in Rc for 1200s in five pointings.
  Visual comparison to the DSS reveals no optical transient. Through calibration to five USNO A-2.0 stars, we estimate the (S/N=3) limiting magnitude to be Rc=19.2.
