GCN Circular 1901
N. Loiseau, M.Gilomo, R.Gonzalez-Riestra, M. Guainazzi, B. Juarez, R. Perez-Martinez, P. Rodriguez, M. Santos-LLeo, and N. Schartel report: 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".
