Geomagnetic Storm Watch: Aurora Alert for Canada & U.S. | NOAA 

A coronal mass ejection (CME) associated with a solar M8 flare is anticipated to arrive at Earth between midday to late on Aug 3, 2024. A moderate geomagnetic G2 Watch has been issued for August 3-4.

The aurora may become visible over northern and upper Midwest U.S. states from New York to Idaho.

The Sun's outer atmosphere, the corona, is structured by strong magnetic fields. Where these fields are closed, often above sunspot groups, the confined solar atmosphere can suddenly and violently release bubbles of gas and magnetic fields called coronal mass ejections (CMEs). A large CME can contain a billion tons of matter that can be accelerated to several million miles per hour in a spectacular explosion. Solar material streams out through the interplanetary medium, impacting any planet or spacecraft in its path. CMEs are sometimes associated with flares but can occur independently.

Stay tuned for updates.
