IAU Circ. 8101)\nhas been performed on May 5, 2003 from 12:30 to 24 UT.\n\nA source positionally consistent with the optical transient of GRB030329\n(Price and Peterson, GCN 1987) has been detected with the EPIC MOS and PN\ncameras.  Its spectrum can be fit by a power law with photon index\n2.0+/-0.25 and absorption smaller than 6x10^20 cm^-2.\n\nThe 2-10 keV observed flux is (2.1+/-0.6)x10^-14 erg cm^-2 s^-1.\n\nComparison with previous X-ray observations obtained with RXTE (Marshall\nand Swank, GCN 1996; Marshall et al., GCN 2052) indicates that the X-ray\nflux decay is consistent with a power law F ~ t^(-1.7).",
