Description
V 0332+53 was first recognized in Tenma observations from late 1983 to January 1984 ([1], [2]). After the detection it was realized that it had been seen by Vela 5B in 1973 ([6]). Follow-up observations by EXOSAT discovered pulsations and allowed the determination of orbital parameters ([3]).
The Tenma observations already showed evidence for a cyclotron line at ~28 keV. Ginga observations (2–60 keV) during an outburst in 1989 found two lines at 28.5 and 53 keV ([7]). During the next bright outburst in 2004, INTEGRAL observations ([4]) found a third cyclotron line at ~74 keV.
