130316 -- Lively solar activity continues at Nancay

NOAA SWPC types III/2, V, VI

I have posted 6 Nancay spectra, and the Solar Dynamics Observatory image that won the Wikimedia picture of the year 2012 second place.

Many thanks to the Nancay Decametric Array Team at the Nancay Radio Astronomy Station of Paris Observatory.

130302 to 130326 is SDO solar eclipse season. The M1.1 flare on 130315 was partially eclipsed and the movies show only the beginning of the flare :-(
