April 2nd solar storm warning and CERN update from BPEarthWatch
From video description:
NOAA forecasters estimate a 60% chance of G2-class geomagnetic storms on April 2nd when a CIR is expected to hit Earth’s magnetic field. CIRs (co-rotating interaction regions) are transition zones between fast- and slow-moving solar wind streams. Density gradients and shock waves inside CIRs often do a good job sparking auroras.
