| | A solitary sunspot | View at EarthSky Community Photos. | Eileen Ferguson captured this image of sunspot AR2738 on April 10. She's in Mallaig, in the Scottish Highlands. Early astronomers first glimpsed sunspots at sunrise or sunset. Nowadays, we know you should never look at the sun without eye protection. Dr Ski in the Philippines has been observing this sunspot, too. He said this morning that it's visible to the eye, maybe via your solar eclipse glasses left from observing the Great American Eclipse of 2017. See more images of AR 2738. | | |
