Subject: V4641 Sgr vanishes in the radio
Dear colleagues,
further VLA observations of V4641 Sgr gave no detection on 12 and 14aug03,
to rms noise levels of 0.079 mJy/bm and 0.073 mJy/bm, respectively, at
4.86 GHz. 1.425 GHz observations on 14aug03 also gave no detection with an
rms noise of 0.16 mJy/beam. I would be very interested to learn of any
further activity at other wavelengths. We will continue to observe with the
VLA on the schedule listed at
http://vsnet.aoc.nrao.edu/~mrupen/XRT/V4641Sgr/v4641sgr.shtml
since the source vanished and re-appeared on a few day to a week timescale
last year, but currently there is no indication of radio activity. Many
thanks to those who managed to get overlapping coverage over the past week!
Cheers,
