SS Cyg

Special Notice #204: Request for monitoring of SS Cygni in support of EVLA/VLBA radio observations

April 15, 2010: Dr. James Miller-Jones (NRAO, Charlottesville) requests the assistance of AAVSO observers to provide rapid notification of the next outburst of the dwarf nova SS Cygni. A confirmed detection of an outburst will be used to trigger-radio wavelength observations of SS Cygni using the NRAO's EVLA and VLBA radio telescopes. Radio observations will be used to study jet formation in dwarf novae, and rapid notification of the onset of outburst is needed. This project follows in the footsteps of a previous campaign by Dr.
