THE LAST AURORAS OF 2022? The year could end with an Arctic light show? NOAA forecasters say there is a chance of G1-Class geomagnetic storms on Dec. 30-31 when a co-rotating interaction region (CIR) is expected to hit Earth's magnetic field. CIRs are transition zones between fast- and slow-moving solar wind streams. They often contain shock waves that do a good job sparking auroras.
