Abstract (from CDS):

D. Galloway, R. Remillard, and E. Morgan, Massachusetts Institute of Technology; and J. Swank, Goddard Space Flight Center, on behalf of the RXTE Instrument Teams, report a new x-ray outburst in a transient last seen in 1970-1971 (Forman et al. 1976, Ap.J. 206, L29): "The ASM position is R.A. = 19h03m33s, Decl. = +3 12'.4 (equinox J2000.0; estimated 3' uncertainty at 90-percent confidence). This position is within the 10' error box originally estimated for X1901+031. The current outburst appears to have begun on 2003 Jan. 31 with a flux of 40(8) mCrab at 2-10 keV, rising to a steady flux of 130 mCrab on Feb. 9 and 10. Brief follow-up observations with the RXTE PCA instrument on Feb. 10 show pulsations with a period of 2.763 s. We encourage efforts to locate the optical counterpart, noting a likely optical companion with an early-type spectrum or Be classification."
