The aurora borealis could be visible tonight for those in the far northern United States along the Canadian border. The northern lights are ribbons of bright light that typically appear around northern latitudes when charged particles from the sun strike the Earth’s magnetic field. Particles lose energy when they collide with our atmospheric gases, giving the aurora a spectacular glow of colors. The Aurora Borealis is visible far from our poles and above northern latitudes during stronger solar events. The aurora was visible in New York Thursday evening and will be visible again tonight!
Earlier Friday, a Level 4 of 5 geomagnetic storm hit Earth, but due to daylight hours in the Eastern Hemisphere, we were unable to see an aurora impact. Geomagnetic conditions have decreased to Level 1 for this evening. A G1 geomagnetic storm may result in small power grid fluctuations, minor satellite impacts, and impacts on migratory animals.
According to NOAA’s Space Weather Prediction Center, “The increase in geomagnetic activity was a response to the arrival of a coronal mass ejection (CME) that left the Sun on June 25. The CME was associated with a large eruption of filaments and analysis indicated a possible arrival on Earth in the form of a flash today. Indeed, a disturbance in the solar wind was observed by an observation satellite a million kilometers from Earth at 5:12 a.m. EDT. It was the vanguard of the CME and when it arrived on Earth, geomagnetic conditions rapidly intensified and eventually reached G3 levels. The G3 warning is in effect until 5:00 p.m. EDT (Friday).”
So what are the conditions for observing what’s left of the geomagnetic storm? There will be decent cloud cover over the Great Lakes and Dakotas, limiting visibility. The best chance for clear skies will be in Montana and northern Idaho.
