Abstract

We present results of UBVRC observations of the symbiotic star CH Cyg before and after optical and X-ray bursts in 2009 at various timescales. Rapid variability was found only during a strong burst (U ~ 9.5 mag) in 2009 October, while during the low state, prior to (U ~ 11 mag) and after (U ~ 9.4 mag) the burst rapid variability was not detected.

Keywords: stars; binaries; symbiotic; individual (CH Cyg); stars; flare; oscillations
