8~4~11

 

STRONG SOLAR ACTIVITY: For the third day in a row, active sunspot 1261 has unleashed a significant M-class solar flare. The latest blast [2] at 0357 UT on August 4th registered M9.3 [3] on the Richter Scale of Flares, almost crossing the threshold into X-territory (X-flares are the most powerful kind). The number of energetic protons around Earth has jumped nearly 100-fold [4] as a result of this event.

The eruption propelled a bright coronal mass ejection (CME) toward Earth. Click on the image to view a movie of the expanding cloud recorded by the Solar and Heliospheric Observatory:

 

 

Moving at an estimated speed of 1950 km/s, this CME is expected to sweep up two earlier CMEs already en route. Analysts at the GSFC Space Weather Lab say the combined cloud [5] should reach Earth on August 5th at 13:55 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
