Co-ordinated Ginga, IUE and VLA observations of flaring activity in sigma-squared CrBThe RS CVn system sigma-squared CrB was observed by the Ginga X-ray satellite for a period of 2.5 days, or approximately 2 binary orbits. Sigma-squared CrB exhibited almost continuous X-ray variability on time scales ranging from minutes to days, including several 'flare-like' episodes with increased coronal temperature. The average count rate was 4.2 +/- 1.2 cts/s (1.7-11.0 keV) corresponding to L(x) of about 10 to the 29.6th erg/s (2-10 keV). Coordinated observations with IUE and the VLA indicate microwave and ultraviolet flaring associated with one X-ray flare.
