OnFocus – In Central Wisconsin, take a look at the night sky between 10:00pm and 1:00am for a chance to view the Aurora Borealis (Northern Lights). A unique series of circumstances (including late moon rise and clear skies) is expected to allow for prime viewing of the lights in the area.
For optimal viewing, set up in an open space away from city and other artificial light sources, and with a view of the northern horizon. It can take 15 minutes for human eyes to adjust to darkness, so plan accordingly.
For your best chance to see it, escape city lights and go to a wide-open space with a view of the northern horizon. Allow about 15 minutes to have your eyes adjust to the darkness.
Geomagnetic Storm Watches are in effect from December 9th – 11th, 2020 due to anticipated CME effects. The CME occurred on December 7th, and was associated with a C7 flare from Region 2790. 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. Therefore, 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 – and another Watch has been issued accordingly. While SWPC forecasters are fairly confident in CME arrival at Earth, timing and geomagnetic storm intensity are less certain.
