Here is an interesting piece of information… Tomorrow a massive plasma flair is due to hit our atmosphere. It is said that this could affect various wireless communications including cell phone reception.

“On August 1st around 0855 UT, Earth orbiting satellites detected a C3-class solar flare. The origin of the blast was Earth-facing sunspot 1092. C-class solar flares are small (when compared to X and M-class flares) and usually have few noticeable consequences here on Earth besides aurorae. This one has spawned a coronal mass ejection heading in Earth’s direction.”

NASA has more info here.
