A BeppoSAX follow up of GRB000528 with the Narrow Field Instruments
started around May 28 at 20:50 UT, i.e. about 12 hours after the GRB.
Preliminary analysis of the MECS (1.6-10 keV) data shows
two previously unknown sources inside the field. The preliminary WFC error
box (BeppoSAX Mail #10) contains both objects, while the refined one
(BeppoSAX Mail #11 and GCN 677) only the second.
Object #1:
R.A.(2000)= 161.365
DEC(2000)= -33.975
Object #2:
R.A.(2000)= 161.287
DEC(2000)= -33.986
both with an error radius of 1.5'.
The source #1 is possibly fading, while the #2 seems to be consistent with
a constant flux. Further and more detailed analysis are in progress.
