S130403-130407 -- Interesting 40 minute long type VI at Nancay

11 active regions today 130407.

The type VI (long series of type IIIs) reached 30 dBab, LCP about 10 dB stronger than RCP:

Studying the Hinode XRT image for 130406, my favoured suspect for this activity would be AR 11718, which produced 8 C flares in 2 days, has an 18% chance of M flares, and Class Beta/Gama Dsi.

Many thanks to the Nancay Decametric Array Team at the Nancay Radio Astronomy Station of Paris Observatory, Hinode and Trinity College Dublin.

130404-130405 -- Plenty of weak activity, below 10 dBab

AR 11711 is still the largest, 5.8E-4 hemisphere, class Beta Cko, 6% M flare probabilty.

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

Below 130403 -- 8 hours of weak type III bursts, several per minute, less than 10 dB above background

I blame AR 11711 for most of the action:
