Request to Monitor U Gem and SS Cyg for Radio Observations
Abstract:
Dr. Elmar Koerding, University of Southampton, England, and his collaborators have requested our assistance in a continuing project to monitor two dwarf novae -- U Geminorum (0749+22) and SS Cygni (2138+43) -- in support of radio observations with the MERLIN and VLA telescopes. This new campaign is a continuation of the project described in AAVSO Alert Notice 345. Koerding and collaborators are attempting to detect and characterize radio emission from dwarf novae during outbursts. Rapid optical detection of an outburst onset will be used to trigger target-of-opportunity (TOO) observations with the MERLIN Array at Jodrell Bank, UK and with the NRAO Very Large Array (VLA) in New Mexico.
