Evolution of multi-frequency emission from Cygnus X-3 in the current giant flare
Abstract
In ATel #12510 we have suggested that microquasar Cygnus X-3 will flare during some weeks after transition from a hard to a ultra-soft X-ray state. That happened after sixty days, when fluxes grew up higher 3 Jy at 15 GHz (AMI LA see http://www.mrao.cam.ac.uk/ dag/Cygnus-X3.html) and up to 3.4 Jy at 37 GHz ( Metsahovi RO, see ATel #12668) on 18 April 2019.
