Abstract

Twelve W UMa systems were observed using the VLA at 5 GHz. Radio emission was detected from two. VW Cep was seen to increase in flux density over a period of three hours from 0.6 mJy to 4.7 mJy, and could have risen further. The flare is interpreted as an event which injected 2 × 10^-13 M_Q of material into the common envelope. V502 Oph was observed as a double source and could have been similar to α Sco, which is explained by the stellar wind from one component interacting with the magnetosphere or stellar wind of the second component.
