Moderate geomagnetic storm forecast for tonight: What to expect
NOAA forecasts a G2 geomagnetic storm with auroras visible in up to 19 U.S. states, caused by coronal mass ejections and high-speed solar wind during the spring equinox.
- On Wednesday, NOAA's Space Weather Prediction Center issued a storm watch for a G2 geomagnetic storm expected to begin at 8 p.m. ET and continue until Thursday at 8 p.m. ET, with auroras visible in nearly 19 U.S. states.
- A coronal mass ejection from the sun is expected to reach Earth, and NOAA links the increased geomagnetic storm risk partly to Friday's spring equinox 'equinox effect.'
- NOAA's ratings show elevated geomagnetic activity, with a six out of nine disturbance level today and conditions rising from G1 late Wednesday to G2 overnight; best viewing is 11 p.m. to 2 a.m. facing north in dark, low–light locations.
- Utilities and satellite operators should monitor systems because a G2 storm can affect high-latitude power systems, spacecraft operations, and HF radio, while migratory animals may face navigation issues, NOAA says.
- Scientists point to equinox-related 'cracks' in Earth's magnetic field that let more solar particles in, intensifying auroras during March's aurora season around the March 20 spring equinox.

Aurora Storms to Peak Over Canada as Sun Ejects Multiple Rounds of Charged Particles to Earth
The night sky will begin glowing with waves of pink, green, and purple lights as spectacular auroras hover over North America in the coming days. Aurora borealis, also called the northern lights, is caused by charged particles from the sun getting trapped in Earth’s magnetic field. To viewers on Earth, they look like dancing lights hundreds of kilometres up, displaying different colours at different altitudes. The most common source of auroras i…
