Extent of blackout of HF (high frequency) radio communication dependent 
upon current X-ray Flux intensity.

Sunspot 1515 which is now about to rotate onto the western limb produced 
a strong M6.9 Solar Flare at 16:32 UTC Sunday afternoon. Because of the 
Sunspots location, any potential CME would be directed mostly away from 
Earth. More updates to follow.
