The NOAA/NWS Space Weather Prediction Center reports that geomagnetic Storm Watches are in effect from December 10th & 11th, 2020 due to anticipated Coronal Mass Ejection (CME) effects giving us a good chance of seeing the northern lights! The CME occurred on December 7th and analysis suggests CME arrival possible late on 9 December, initially resulting in G1 (Minor) storm levels. As CME effects continue, activity is likely to increase, especially if the magnetic field carried with the CME connects well with Earth’s magnetosphere. The potential for strong storm levels exists and a G3 (Strong) Watch is in effect for December 10th. CME-related disturbances are forecast to continue into 11 December, likely resulting in G2 (Moderate) storm levels
As a quick rule of thumb, we can occasionally see Northern Lights at the G1 level, often at G2 and almost definitely at G3. Here’s hoping for clear skies!!
Aaron took this photo at Otter Creek in the Sleeping Bear Dunes National Lakeshore back in March of 2015 & shared: A very memorable night. After seeing all 4 indicators in red on [a now defunct aurora tracker website] (and I had never seen that before), I bolted for the lake with what was an already late start. Soon after arriving I punched through the ice while jumping from flow to flow in the shallows. This was the first time I have ever shot these and despite having one leg wet to the knee I managed to stay out for five hours on sheer excitement.
See more in his Aurora Borealis gallery on Flickr & here’s hoping for some clear skies tonight!
