Abstract

The light curve of the nearest S-type symbiotic binary, CH Cyg, showed an unprecedented drop in visual magnitude in 1996. This event bears striking resemblance to an earlier outburst phase of CH Cyg when, following extreme fading of the visual magnitude in 1984, a multi-component jet was ejected and first detected at radio wavelengths. In October 1996, we started VLA monitoring of CH Cyg to probe the nature of this recent activity.
