Sunspots Today
Sunspots are cooler, darker patches where the Sun's magnetic field is knotted and intense — and they're where flares are born. Counting them is the oldest measure of solar activity, and their rise and fall traces the Sun's roughly 11-year cycle. Here are the active regions on the Sun's face right now.

Reading an active region
Each numbered region (e.g. AR4465) carries a magnetic classification — the more complex and tangled the field, the higher the chance it will erupt. SWPC even publishes per-region odds of a C, M or X flare in the next day. A big, magnetically complex group is the single best clue that the Sun is about to get interesting; a blank, spotless disk means a quiet stretch ahead.
The solar cycle
The number of sunspots swells and fades over about 11 years, from a quiet solar minimum to a busy solar maximum and back. The monthly sunspot number and the 10.7 cm radio flux (F10.7) shown above are the standard yardsticks. Near maximum, flares and aurora are far more common — which is why the aurora has been so active lately.
