GRB030706 was detected by Konus-Wind at 00:02:15.262 UT
and Helicon-Coronas-F at 00:02:17.053 UT.

We have triangulated it to a preliminary annulus centered at
RA(2000) = 85.881 deg,
Decl(2000) = 21.043 deg,
Radius = 62.2 +/- 1.9 degrees (3 sigma ).
This annulus intersects the IPN annulus (GCN 2292Loading...
 
 ) to form two
error boxes, only one of which has the correct ecliptic latitude.
Preliminary 3 sigma error box has approximate area of 1200 sq. arcmin :

                        RA(2000)    Dec(2000)
ERROR BOX CENTER:      146.691        1.828
ERROR BOX CORNER 1:    148.567        1.337
ERROR BOX CORNER 2:    144.827        2.349
ERROR BOX CORNER 3:    144.862        2.432
ERROR BOX CORNER 4:    148.603        1.422
