Alert Notice 360: Request to Monitor U Gem and SS Cyg for Radio Observations

November 5, 2007: 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.
