During maximum of eclipse today Sun noise drop down 6dB, compare with 04/01/2011 eclipse http://www.ok1dfc.com/eme/mereni/eclipse_04_01_11.htm when we had 80% and than noise drop down -6,5dB

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/SEgoogle2001/SE2015Mar20Tgoogle.html
>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.
