X-RAY TRANSIENT REPEATER IN THE GALACTIC CENTER REGION
The Green Bank Earth Station has scanned this region on several dates.
The data for 95 December 20 are presented for
8.35 and 14.35 GHz.
The data are available in FITS
J.D. Kurfess, J.E. Grove (Naval Research Laboratory), D. Messina
(SFA, Inc.) and J.Tueller (Goddard Space Flight Center) report:
"OSSE observations on the Compton Observatory have been acquired which
further constrain the position of the source first reported in IAUC 6272.
Data obtained from Dec. 15-17 with the four OSSE detectors
scanning along the galactic plane provide a galactic longitude position
between -0.27 and +0.17 degrees (95% confidence). The OSSE field-of-view
normal to the scan direction is 11.4 degrees FWHM. When coupled with the
position reported in IAUC 6275, the location of the transient repeater is
constrained to a region with the following coordinates as vertices:
R.A = 17h44m34s, Decl. = -28o.576; 17h45m58s, -28o.774; 17h43m11s, -29o.026;
The locations of the corners of the boundaries are marked by crosses
in the images. The images are produces from scanning the 45'
telescope across the center of the region. The brightest source
in the images is the galactic center. The extended emission and the
sky background is removed by median filtering of the scanned data.
The data are in Kelvins, where 1 Kelvin corresponds to roughly 50
Except for the Galactic center, no significiant features are
