CO-ROTATING INTERACTION REGION: Geomagnetic storms (G1-class) are possible on April 29th 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 contain shock waves and compressed magnetic fields that do a good job sparking auroras.
