IT’S BACK! A BIG HOLE IN THE SUN’S ATMOSPHERE: During solar minimum, long-lasting holes open in the sun’s atmosphere, releasing streams of solar wind into space. One of those holes is turning to face Earth now, and it’s a big one:
We’ve seen this hole before. It opened in the summer of 2018 and has been spinning around as the sun rotates, lashing Earth with solar wind approximately once a month. The last time our planet felt its gaseous emissions, in late Jan. 2019, bright auroras surged around the Arctic Circle and some of the lights even spilled into the USA.
G1-class geomagnetic storms are likely on Feb. 26th or 27th when the solar wind returns. Stay tuned!
