- Аннотация: We report on the recent optical photometric and spectroscopic signatures of the hard X-ray recovery of the symbiotic system CH Cyg (see ATEL #2046). Our UBVR_C photometry taken at the observatories of the Astronomical Institute of the Slovak Academy of Sciences showed that CH Cyg started a gradual brightening in the U photometric passband from 2008 October (U ~ 11.9) to the present.
