Two sky events shared one date this August. A total solar eclipse swept across Greenland, Iceland, northern Russia, the Atlantic Ocean, Spain and a small corner of Portugal on Wednesday, Aug. 12, according to NASA, which published a photo of totality seen from San Millán de los Caballeros, Spain. NASA’s eclipse guide says Spain and the northwestern tip of Portugal saw the Sun fully covered only in the late evening, shortly before sunset, and that totality lasted less than two minutes for most people in the path. Parts of the U.S., most of Canada, much of Europe and northwestern Africa saw a partial eclipse, NASA says.

Later that night the Perseid meteor shower peaked. NASA’s August skywatching tips put the peak on the evening of Aug. 12 into the early morning of Aug. 13 and note that the New Moon on the 12th left skies ideally dark. The Perseids return every year when Earth passes through debris from Comet Swift-Tuttle, NASA explains.

NASA’s safety rule holds for every eclipse: only during totality can viewers look at the Sun without protection, and every partial phase calls for eclipse glasses or a handheld solar viewer that meets the ISO 12312-2 standard. NASA stresses that ordinary sunglasses, however dark, do not protect the eyes.
