A single flare event with a rise time ∼ 7 s and a decay time ∼ 40 s was observed by Goddard Cosmic X-ray Spectroscopy Experiment on OSO-8 during observations of 3U0614 + 09 in 1975 September. The possibility is discussed that the source was 3U0614 + 09, which has been compared to the low-mass binary Sco X-1. The spectra during the event could be fitted with blackbody (kT = 0.8−1.1 keV) or thermal bremsstrahhmg (kT = 1.1−2.5 keV) models with absorption by cool material. In the blackbody model the source was ∼ 106 cm in size.
