Abstract
Uhuru observations of the galactic plane indicate the presence of four X-ray sources not previously characterized as transient: MX 0836-42, A1918+14, 4U 1730-22, and 4U 1807-10. X-ray light curves as well as positional and spectral information are presented for these sources and for 4U 1908+00, a recurrent transient source. The frequency, duration, and intensity of galactic-plane transients during the Uhuru lifetime are discussed. Transient X-ray sources appear to be divided into two classes based primarily on an observed bimodal spectral temperature distribution.
