• GCN notice #1409
  K. Hurley and T. Cline, on behalf of the Ulysses, Mars Odyssey, and Konus GRB teams,

  W. Boynton, C. Fellows, K. Harshman, C. Shinohara and R. Starr, on behalf of the GRS/Odyssey GRB team, report:
  Ulysses, Konus-Wind, and HEND observed this burst at 64234 s. As observed by Ulysses, it had a duration of ~1.5 s, which probably places it in the short-duration, hard spectrum GRB category. Its 25-100 keV fluence was ~6E-6 erg/cm^2, and its peak flux over 0.5 s was ~1.4E-6 erg/cm^2 s. We have triangulated it to a preliminary, 3 sigma error box whose area is ~ 25 square arcminutes, whose coordinates are:

      RA(2000)                 DEC(2000)

  This error box may be improved.
• GCN notice #1410
  P.A. Price, B.P. Schmidt (RSAA, ANU) and T.S. Axelrod (Steward Obs, Arizona) report:
  We have observed the error-box of GRB 020603 (Hurley et al., GCN #1409) with the robotic 50-inch telescope at Mount Stromlo Observatory, commencing at 2002 June 5.69 UT. Exposures consisted of 3x300 sec integrations in MACHO_R, and cover the entire error box to a limiting magnitude of R ~ 19 mag. We do not find any optical afterglow candidate within the error box on visual comparison with the second Digitised Sky Survey.

• GCN notice #1412

  I. Mitrofanov, D. Anfimov, A. Kozyrev, M. Litvak and A. Sanin on behalf of the HEND/Odyssey GRB team,

  W. Boynton, C. Fellows, K. Harshman, C. Shinohara and R. Starr, on behalf of the GRS/Odyssey GRB team, report:
  The initial triangulation of this burst, given in GCN 1409, was based on the data of the only three spacecraft available at that time, and therefore gave two alternate positions, one of which appeared to be ruled out based on its ecliptic latitude. However, this burst was also observed by RHESSI. The addition of this fourth spacecraft to the triangulation indicates that the burst in fact must have originated from the alternate error box. The area of this error box is approximately 19 square arcminutes and its coordinates are:

      RA(2000)                 DEC(2000)
   15 h 46 m 35.53 s    -22 o 15 '  12.95 "  (CENTER)
   15 h 46 m  2.21 s    -22 o 18 '  52.67 "  (CORNER)

   15 h 46 m 48.71 s    -22 o 12 '  20.76 "  (CORNER)
   15 h 47 m  8.96 s    -22 o 11 '  32.14 "  (CORNER)
  

  The other properties of the burst given in GCN 1409 have not changed.
  We regret the inconvenience which this error may have caused.
• GCN notice #1413: GRB 020603, R-band observation
  J. M. Castro Cerón, ROA (San Fernando), M. Pedani, TNG (La Palma) J. Gorosabel and A. J. Castro-Tirado, IAA-CSIC (Granada)
  report:
  "We have imaged the central part of the updated IPN error box for GRB 020603 (Hurley et al., GCN 1412) with the 3.58-m Telescope Nazionale Galileo (+ DOLORES, 9.4' x 9.4' FOV) at La Palma. A single R-band frame (300-s exposure time) was obtained on Jun 6.135 UT (i.e. 57 hours after the GRB). No new objects are seen within the fraction of the error box imaged (about 80 %) down to the DSS-2 (R-band) limiting magnitude."

• GCN notice #1414
  M. Nysewander, L. Johnson, D. Moschler, J. Richuso (U. North Carolina), and D. Reichart (Caltech) report:
  We observed the entire ~19 square arcminute error box of the ~1.5 second duration GRB 020603 (GCN 1409, 1412) with the 0.6 meter Morehead Observatory telescope beginning 2.36 days after the burst. We integrated without filter for ~2800 seconds per pointing x 2 pointings through scattered cirrus and relatively high airmass.
  Visual comparison with the DSS reveals no transients down to our limiting magnitude, which we estimate to be V ~ 18.5 mag.
• GCN notice #1423
  A. Henden (USRA/USNO) reports on behalf of the USNO GRB team:
  We have acquired BVRcIc all-sky photometry for an 11x11 arcmin field centered at the IPN coordinates for the short/hard burst GRB020603 (Hurley et al., GCN 1409) with the USNOFS 1.0-m telescope on one photometric night. Stars brighter than V=14.0 are saturated and should be used with care. We have placed the photometric data on our anonymous ftp site: ftp://ftp.nofs.navy.mil/pub/outgoing/aah/grb/grb020603.dat. The astrometry in this file is based on linear plate solutions with respect to UCAC2. The external errors are less than 100mas. The photometry has potential zeropoint error of about 0.02mag.
