On the West Coast, aurora may be visible on the horizon in parts of northern California, Northern Nevada and much of Utah. The aurora forecast for this geomagnetic storm includes the potential for aurora overhead as far south as Pennsylvania, Iowa and Oregon by Saturday night.
Geomagnetic storms can deliver spectacular aurora on Earth. (G1 storms are minor, while G5s are considered extreme.) The G3 storm watch is in effect here on Earth both Saturday and Sunday. The storm is rated a "G3," which is the third level of NOAA's five-level geomagnetic storm scale. The solar flare was the second most powerful eruption from the sun this year, according to . As an aurora enthusiast, here’s the main things I look for at a glance on this page: The green donut-ring aurora forecast simulation provided by NOAA (I’m in Alaska, USA so that’s our go-to). "Geomagnetic storms on Earth can affect electrical grids, GPS navigation systems and radio and satellite telecommunications," the Center said. The Space Weather Prediction Center notified power grid operators, satellite operators, airlines and other customers about potential impacts of a geomagnetic storm.
Marybeth said: The aurora sparked on this night was from a combination of an M-class. To find the clearest sky near you, use the light pollution map and dark site finder. Marybeth Kiczenski took this image of the northern lights from Bayfield, Wisconsin, in early November 2021. To get your best chance of seeing the lights, NOAA suggests getting away from the city and light pollution. As predictions and times are due to change, you can keep track of the geometric storm using NOAA's 30-minute prediction.
