Image Details:

Another cool sunspot has come around the Sun's eastern limb (it really is cool; around 2,000°C cooler than the surrounding surface). Full disc images taken at 26X. Close-up captured at 100X. The whiteish areas near the sunspot are called "plage" (from the French for "beach") and are easily visible thru a solar filter.
