THAT SUNSPOT IS GETTING BIGGER: Sunspot AR3105 emerging over the sun's eastern limb is growing rapidly: movie. We've seen this sunspot before. It's AR3089 returning after a 2-week trip around the farside of the sun. Instead of decaying, the old sunspot seems to be growing again. If this continues, it could soon pose a threat for Earth-directed flares. https://www.spaceweather.com/images2022/20sep22/emerging_strip.gif

AN EXPLOSION OF AURORAS OVER NORWAY: Last night in Tromsø, Norway, there was an explosion of auroras so intense "it made my guests scream and laugh at the same time," says aurora tour guide Markus Varik. "We had no idea the night would turn out like this!"

CHANCE OF STORMS TODAY: NOAA forecasters say that a minor G1-class geomagnetic storm is possible on Sept. 23rd when a high-speed stream of solar wind is expected to hit Earth's magnetic field. The gaseous material is flowing from an equatorial hole in the sun's atmosphere. High-latitude auroras are possible when the windy stream arrives.

GEOMAGNETIC STORM WATCH: A solar wind stream is approaching Earth, and it could spark a G1-class geomagnetic storm when it arrives on Sept. 30th or Oct. 1st. The gaseous material is flowing from a double equatorial hole in the sun's atmosphere. High-latitude sky watchers should be alert for auroras on those dates.
