View at EarthSky Community Photos. | We first heard of the new sunspot – labeled AR 2738 – from Dr Ski in the Philippines on April 9. He posted this photo and wrote: “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 disk 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 through a solar filter.” Thank you, Dr Ski.
