E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team,report:

Ulysses, INTEGRAL (SPI-ACS), and Konus-Wind  observed this GRB at 04637
seconds.  As observed by Ulysses, it had a duration of approximately 8
seconds, a 25-100 keV fluence of approximately  3.5E-06 erg/cm2, and a
peak flux of approximately  7.6E-07 erg/cm2 s over 0.25 seconds.

We have triangulated it to a preliminary annulus centered  at RA,
Decl(2000)= 332.708, -37.556 degrees, whose radius is 76.840 +/-  0.037
degrees (3 sigma ).

This annulus may be constrained and/or improved, but as the event was
not observed by Mars Odyssey, a small error box cannot be derived for
it.

INTEGRAL SPI-ACS GRB team, report:

GRB030501B was detected by Konus-Wind at 01:17:21.824 UT
and Helicon-Coronas-F at 01:17:20.607 UT.

We have triangulated it to a preliminary annulus centered at
RA(2000) = 224.210 deg,
Decl(2000) = -21.142 deg,
Radius = 81.01 +/- 0.68 degrees (3 sigma ).
This annulus intersects the IPN annulus (GCN 2186
Loading...
 
 ) to form two
error boxes, only one of which has the correct ecliptic latitude.
Preliminary 3 sigma error box has approximate area of 400 sq. arcmin :
