Our Sun is throwing a Tantrum - UPDATE - Huge X6.9
http://spaceweather.com/STRONG SOLAR ACTIVITY: On August 4th, active sunspot 1261 unleashed a strong solar flare, the third in as many days. The blast, which registered M9.3 on the Richter Scale of Flares, hurled a bright coronal mass ejection (CME) almost directly toward Earth.
Moving at an estimated speed of 1950 km/s, this CME is expected to sweep up an earlier CME already en route. Analysts at the GSFC Space Weather Lab say the combined-CME should reach Earth on August 5th at 10:00 UT plus or minus 7 hours: "The impact on Earth is likely to be major. The estimated maximum geomagnetic activity index level Kp is 7 (Kp ranges from 0 - 9). The flanks of the CME may also impact STEREO A, Mars and Mercury/MESSENGER." High-latitude sky watchers should be alert for auroras.

No wonder everyone is dumping their stocks.
Not to worry though, it's only a very big "M" and not an "X".
