GCN Circular 410
K. Hurley, on behalf of the Ulysses GRB team, and Scott Barthelmy, on behalf of the GCN team, report: We have derived a preliminary IPN annulus for BATSE trigger #7766 (GRB990915) using Ulysses and BATSE data. This annulus is centered at RA(2000)=22h 31m 51s, Decl(2000)=+14o 45' 21", and has a radius of 86.361o +/- 0.09o (3 sigma). This annulus just crosses the updated COMPTEL contours for this burst, and slightly misses the BATSE LOCBURST position. A map may be found at ssl.berkeley.edu/ipn3/990915/. This annulus will be refined considerably when the final data become available.
