If at all possible try and make an accurate measurement of sun noise during 
the eclipse period on what ever band you can. Ideally we are looking for the
ratio between normal level (measured on the same day) and the minimum sun 
noise occurring at the time of maximum shadowing. You can get the timing for
your exact location from this link. http://eclipse.gsfc.nasa.gov/SEgoogle/

We believe that we can possibly accumulate some interesting measurements on 
a non-quiet sun which might indicate how much noise comes from the corona 
compared to the disc. This influences what value is used for the solar 
diameter when making beamwidth measurements for example.
