The very soft X-ray transient H1853 + 60The detection of a new soft X-ray transient, H1853 + 60, using data from the Low Energy Detectors (LEDs) on the HEAO 1 A-2 experiment, is reported. Although the solar flare hypothesis cannot be ruled out, the similarity between this X-ray transient's temporal and spectral characteristics and those of several other transients observed by HEAO 1 LEDs, suggest a common emission mechanism for these events. It is unlikely that more transients as strong as these will be discovered, except on an individual scan basis.
