Soft X-Ray Transient

M. Oda and the Hakucho Team telex: "The Hakucho satellite discovered a soft x-ray transient when it maneuvered the detectors toward the galactic center region on Apr. 30. The location of the source is R.A. = 17h41m +/- 1m, Decl. = -28o.0 +/- 0o.1 (equinox 1950.0). The x-ray flux is ~ 0.25 Crab over the 1-10-keV range, with no significant increase or decrease. There are no known x-ray sources within the error box. We shall modify the schedule (IAUC 3681), and Hakucho will continue to observe this source until around May 15, unless anything unexpected occurs. We urge observers to search for the optical or infrared counterpart of this transient."
