Quick-Look-Analysis of the XMM-Newton observation
of GRB030227 (G. Gotz et al. GCN 1895 and 1896), based on
1 and 2 ks non-simultaneous exposures in the EPIC MOS and pn
cameras, respectively, shows the presence of one source in the
refined IBIS error circle:
S1 (J2000): R.A. = 4h 57m 33s Decl. = 20deg 29' 9"
with an estimated EPIC/pn count rate of 0.2 [counts/sec];
A second source, only marginally consistent with the error box
reported in GCN1896, is detected in the MOS cameras:
S2 (J2000): R.A. = 4h 57m 17s Decl. = 20deg 30' 18"
At this stage of reduction the positional error is expected to
be less than 6".
