Giant sunspots, solar flares, aurora alert! Gowrishankar Lakshminarayanan called this: “… a surreal sunset from Fire Island Lighthouse in Fire Island, New York. You can see the 2 giant sunspots – AR2673 and AR2674 – as the sun is setting.” The sunspots are visible to the eye, but you must use a safe solar filter. Your eclipse glasses will work!
