  K. Hurley, on behalf of the Ulysses GRB team, T. Cline, on behalf of the NEAR and Konus Wind GRB teams, and E. Mazets and S. Golenetskii, on behalf of the Konus Wind GRB teams, report:
  Ulysses, Konus Wind, and NEAR observed this burst at 26072 s UT. As observed by Ulysses, its duration was ~30 s, its 25-100 keV fluence was ~9.2 x 10^-6 erg/cm^2, and its peak flux over 0.25 s was ~1.1 x 10^-6 erg/cm^2 s. We have triangulated it to an ~60 sq. arcmin. error box whose preliminary, 3 sigma coordinates are:

• GCN notice #714
  C. Bartolini, R. Gualandi, A. Guarnieri, A. Piccioni, Astronomy Department, Bologna University and Bologna Astronomical Observatory, and E. Palazzi, E. Pian, N. Masetti, ITeSRE-CNR, Bologna report:
  On June 17.88 - 17.92 UT we have imaged the field of GRB000616 (K.Hurley et al. GCN n.711) with the 152 cm telescope of Loiano, R color. Because of the sky conditions and the full moon we were not able to detect any object fainter than 18th mag. Within this limit a preliminary quick inspection of the field does not show any new object with respect to the POSS.
• GCN notice #708
  A. Di Paola, L.A. Antonelli, G. Licausi, R. Speziali, Osservatorio Astronomico di Roma, G. Valentini, Osservatorio Astronomico di Teramo, Italy, on behalf of a larger collaboration report:
  We have imaged the BeppoSAX revised error-box of GRB000615 (GCN 705) using the AZT-24 1.1-meter telescope at Campo Imperatore (AQ). We observed for a total exposure time of 3600 sec in J-band and 1500 sec in K-band. Observations started at June 15.9792 UT about 17.2 hours after BeppoSAX trigger time (GCN 703) and ended at 16.09167 UT. We imaged the field in J-band twice with a time interval of about 2 hours. The limiting magnitude in the combined images is J=20.5 mag and K=17.5 mag (S/N=3) with an average seeing of 2.5" . A preliminary comparison of the first 900 sec with the last 1500 sec J-band images reveals no obvious fading objects. The comparison of the combined 3600 sec J-band images with the POSS-II red plate and the FLWO field (GCN 706), reveals no obvious new objects.
  Further observations of this field are planned at Campo Imperatore.
