Australia Telescope Compact Array observations of V4641 Sgr on 7 July show a clear
detection at 6 and 3 cm (4.80 and 8.64 GHz). For observations
taken between 14.5 to 19.0 hours UT, the flux density was seen to vary
between approximately 5mJy and 30mJy. In particular, a sudden increase
was noted at 16.4 UT, followed by a decay over several hours. The 3cm
flux density peaked approximately 20 minutes earlier than the 6cm
signal.
