waking up

The sun woke up. Flares are in the high-C class levels or 10 times more powerful that in the last days, mainly coming from limb sunspots AR4392 at east and AR4381 and 4384 at west. But, in addition, a huge coronal hole appeared on the sun face, rising the Kp index to 6 and wind speed to 650+ k/s. Pi day may bring surprises !
