CO-ROTATING INTERACTION REGION: NOAA forecasters estimate a 60% chance of G1-class geomagnetic storms on May 20th when a co-rotating interaction region (CIR) is expected to hit Earth. CIRs are transition zones between slow- and fast-moving streams of solar wind. Strong magnetic fields and density gradients inside CIRs often do a good job sparking auroras.
