I remember everyone enjoying the last big solar flare and we had another pretty large one last night.
STRONG SOLAR ACTIVITY: For the third day in a row, active sunspot 1261 has unleashed a strong M-class solar flare. The latest blast at 0357 UT on August 4th registered M9.3 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 as a result of this event. Stay tuned for updates.

You people who live as far north as San Francisco go outside the next few nights, who knows you might be treated to an aurora display.
