Minor Geomagnetic Storm Expected to Graze Earth This Week

A coronal mass ejection from the sun, coinciding with the autumnal equinox, could cause minor disturbances and auroras on Wednesday.

A coronal mass ejection (CME) erupted from sunspot AR3835 on Sunday, sending solar plasma toward Earth.
The CME is expected to glance off Earth's magnetosphere on Wednesday, potentially causing a minor geomagnetic storm.
This event coincides with the autumnal equinox, a period when geomagnetic storms are more likely due to the alignment of Earth's magnetic field with the sun's.
The National Oceanic and Atmospheric Administration (NOAA) predicts the storm will be a G1 or 'minor' class, the weakest category of geomagnetic storms.
While the storm may cause minor disruptions in communications and power grids, it could also result in visible auroras in northern regions of the U.S.
