[Moon] [Moon-Net] Partial eclipse tomorrow

[M. Watanabe]

Hi Peter and other researchers,

It's so interesting to see what happens during the eclipse.  
The radio-size of the sun would be a nice point of view! 
A few years back in JA, total eclipse occured and some 
guys measured and recorded the data on microwave bands.

Incidentally I have to move this week and the next, and 
no time to maintain my shack for a while.   

I will live closer to my shack, 5-10 minutes drive, from April.

This is the end of my great journey every time ca. 600km 
back and force for the radio/EME. Thanks a lot!!

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.
