Observations of a transient X-ray source with regular periodicity of 6.75 min

Nature volume 254, pages 578–580 (1975)Cite this article

Abstract

DURING planned observations, by the satellite Ariel V, of the X-ray source Cen X-3 (3U1118-60), a previously unreported source nearby was detected by the collimated proportional counter of 100 cm2 provided by the Mullard Space Science Laboratory. The source was monitored over a period of 39 d between December 19, 1974, and January 27, 1975. Here we report measurements of the light curve, spectrum and of a regular variability with period of 6.755 ± 0.010 min. The position of the source is given in the accompanying letter1.
