Subject: [AAVSO-DIS] Update on CV radio campaign

Hello everyone,

I would like to present an update to the campaign to search for radio 
emission from dwarf novae (alert notice 345):

Following your prompt reports that SS Cyg was going into outburst we 
have triggered both the VLA and MERLIN. As SS Cyg was setting for the 
VLA a few hours after the confirmation of the outburst we unfortunately 
did not get onto the telescope during that night. However, we did get 
observed once the source was visible again - and got a good detection. 
This was still during the rise of the outburst, while the optical V-band 
magnitude was roughly 10 (luckily this outburst had a slow rise). Thank 
you for the trigger!

Following this first radio observation we monitored the source with the 
VLA (currently 8 observations) and also obtained two continuous days of 
MERLIN observations. Already these detections are nice as they show that 
our earlier radio detection of SS Cyg is not fluke - but is 
reproducible. It is yet too early to say anything further about possible 
results, but it looks like we will obtain a good radio light-curve that 
we can compare with your optical data.

We will continue to monitor the source in the radio bands as long as it 
is visible. It will be especially interesting to compare the radio data 
with the optical light-curve during the decline of the outburst. We 
would therefore be grateful if you could continue your excellent dense 
monitoring as long as possible during the decline.


Thank you very much for your help and clear skies,

Elmar Koerding for the CV radio team.
