"Earth Braces for Potential Geomagnetic Storm from Strong Solar Flare and Multiple Sunspots"

NOAA has warned that a strong M-class solar flare may hit Earth, which could generate a geomagnetic storm. The sunspot AR3280, which has a beta-gamma magnetic field, is the probable origin of the impending solar flare. Although Earth's magnetosphere is effective in blocking solar flares, some charged particles can penetrate through and result in magnetic disruptions referred to as geomagnetic storms or substorms, which can interfere with radio communications and the power grid. NOAA monitors solar flares and the Sun's behavior using its DSCOVR satellite.
