From IAUC 6683: GRB 970616 F. E. Marshall, GSFC; T. Takeshima, and S. D. Barthelmy, USRA and GSFC; C. R. Robinson, USRA and MSFC; and K. Hurley, University of California at Berkeley, report the detection of an x-ray afterglow for the gamma-ray burst detected with BATSE on June 16.7568 UT. Scanning observations with the Proportional Counter Array on the Rossi X-ray Timing Explorer (RXTE) 4.0 hr after the burst revealed a source at R.A. = 1h18m.9 +/- 0m.7 (90-percent statistical confidence), Decl. = -5 30' +/- 18' (equinox 2000.0) with a countrate of 4.5 +/- 1.6 counts/s or 1.1 x 10E-11 erg sE-1 cmE-2 in the band 2-10 keV. It is the brightest source detected within the 2-deg BATSE error circle, and it also overlaps the preliminary inter-planetary network (IPN) annulus determined from the time difference in the BATSE and Ulysses detections. The IPN annulus has a radius of 49.808 deg, is centered at R.A. = 22h10m30s, Decl. = -27o24'.8, and has a full width of 4'.6. An annulus with a smaller width will be available after further processing. The intersection of the error regions has corners at 1h19m.6, -5 49'; 1h19m.6, -5 40'; 1h18m.4, -5 12'; 1h18m.2, -5 16'. A subsequent RXTE observation on June 18.08 detected no significant flux from this position, with a preliminary 90-percent confidence upper limit of 2.5 counts/s. -eof-
