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:

    RA(2000)                 DEC(2000)
 11 h 20 m 10.97 s     26 o 16 '  41.19 "  (CENTER)
 11 h 20 m 23.84 s     26 o 16 '   7.00 "  (CORNER)
 11 h 18 m 55.98 s     26 o 29 '  28.37 "  (CORNER)
 11 h 21 m 24.90 s     26 o  3 '  55.26 "  (CORNER)
 11 h 19 m 58.09 s     26 o 17 '  15.33 "  (CORNER)

This localization can be improved.

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.
