Abstract
The region containing the Perseus flasher (Katz et al., 1986) was observed for 5.4 hr with the EXOSAT observatory. Upper limits (2 σ levels of confidence) to a point source with a steady X-ray flux were 2×10-12erg cm-2s-1 (0.1 - 2 keV) and 6×10-12erg cm-2s-1 (1 - 20 keV). Upper limits (4 σ level of confidence) to X-ray flashes of ≡1 s duration were 4×10-9erg cm-2s-1 (0.1 - 2 keV) and 7×10-10erg cm-2s-1 (1 - 20 keV).
