Geomagnetic storm conditions expected Tuesday & Wednesday


Geomagnetic storm conditions are expected on Tuesday and Wednesday.


The Space Weather Prediction Center has issued a G1 (Minor) geomagnetic storm watch for Tuesday and a G2 (Moderate) watch for Wednesday due to the arrival of multiple Coronal Mass Ejections associated with flare activity from an active sunspot region.


A geomagnetic storm is a disturbance of the Earth's magnetosphere caused by a solar wind that interacts with the Earth's magnetic field.


Coronal Mass Ejections are large expulsions of plasma and magnetic field from the Sun's corona.


During G1 events weak power grid fluctuations can occur. Migratory animals are affected at this and higher levels; aurora is commonly visible at high latitudes.


For G2 events, high-latitude power systems may experience voltage alarms, long-duration storms may cause transformer damage. HF radio propagation can fade at higher latitudes, and aurora has been seen at 55° geomagnetic latitude.
