  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 37179 seconds. As observed by Ulysses, it had a duration of approximately 0.2 seconds, a 25-100 keV fluence of approximately 3.2E-07 erg/cm2, and a peak flux of approximately 1.3E-06 erg/cm2 s over 0.25 seconds. Its duration and spectrum place it in the "short/hard" burst category. We have triangulated it to a preliminary, 3 sigma error whose approximate area is 11. sq. arcmin. and whose coordinates are:

• GCN notice #917
  E. Berger (Caltech) and D. A. Frail (NRAO) report on behalf of a larger collaboration:
  "Beginning on January 20.50 UT we observed the IPN error box of the short/hard burst, GRB010119 (GCN#916) with the VLA at 4.86 GHz. We find no new sources which are not cataloged in the NRAO VLA Sky Survey (NVSS), with a flux density larger than 350 microJy (5-6 sigma)."

• GCN notice #919
  P. A. Price, G. Morrison and J. S. Bloom (Caltech) report on behalf of the larger Caltech-NRAO-CARA GRB collaboration:
  "We observed the IPN error box of the short/hard GRB010119 (Hurley et al., GCN #916) with the Palomar 60-inch telescope on 2001 Jan 20.56 and 21.57 UT (1.13 and 2.14 days after the burst respectively) in difficult conditions. In particular, the seeing was ~ 5.5 arcsec and 3.5 arcsec for the two epochs, respectively. From visual inspection of the combined images, we do not detect any objects within the error box that are not present on the Digital Sky Survey 2 red plate. Limiting magnitudes of our images are R ~ 18 mag and R ~ 21 mag for the first and second epoch respectively, based on comparison with stars in the USNO-A2.0 catalogue. The quality of the first epoch image does not allow us to search for variable objects between the two epochs."

• GCN notice #920
  A. Oksanen and M. Moilanen (Nyrölä Observatory GRB-team), H. Yamaoka (Kyushu Univ. VSNET GRB-team), and A. Henden (USRA/USNO) report:
  We have observed the entire IPN error box of GRB010119 (Hurley et al., GCN 916) as part of the monitoring effort by the AAVSO GRB network. This GRB was of the short-hard variety and so is of considerable interest. However, at a galactic latitude and longitude of bII=4.9, lII=43.9, the burst occurred in a dense starfield with no visible background galaxies, indicating considerable extinction. The observation was made with the Nyrölä Observatory 0.4-m telescope and Rc-filter on 010121.17 UT, between the two Palomar observations reported by Price, et al. (GCN 919). A total of 12 two-minute exposures were stacked, yielding a limiting magnitude of approximately R=19.5 in 3.4arcsec seeing. The resultant image can be found at http://www.jklsirius.fi/grb/grb010119nyt.fit All objects on this image are also visible in the scans of the POSS-2 red plate from the NOFS PMM pixel server.
