We just had another of our monitoring looks for old X-ray transients, and 
must to our
surprise there appears to be a preliminary result of 1.6 mJy radio source 
at the position of

  V4641 Sgr (XTE J1819-254)

I looked at the RXTE weather page and note that the last point plotted 
indicates 18 ct/sec,
or 1/4 of a Crab.

Each of these is only one point, but the radio detection is excellent and 
appears exactly on
position.

So, we are begging for more time ASAP and I suggest that those who are 
interested
consider looking at  V4641 Sgr (XTE J1819-254).

Cheers,
Bob
