A fast-rise radio flare in Cyg X-3
Abstract
We have detected new activity in X-ray binary Cyg X-3 (see ATEL #727, #806, #807, #809). We have observed Cygnus X-3 with RT32 (Institute of Applied Astronomy RAS, Russia) on 5 June 2006 (MJD53891) at 2.3 and 8.5 GHz. This date is within the interval covered by the Ryle telescope in Cambridge (UK) at 15 GHz, but the observations were not simultaneous. We have detected a very fast rise in the flux density at 2.3 and 8.5 GHz over a period of less 3 hours, after the slower increase of the flux at 15 GHz.
