Waking up

[ellarien]

The Sun has been pretty active this week. The highlight was an X2.2 flare on the 15th (that's a big one, though still less than a tenth of the size of the monster flares of late October 2003; the biggest so far this cycle by quite a margin.) There might be aurora tonight even here -- though it'll probably too cloudy and/or moonlit to see much.






Below the cut is yesterday's APOD (2kx2k pix), showing the flare at the 193 Angstrom wavelength as seem by AIA.
