Heads up, aurora chasers! A robust photo voltaic storm is on the way in which.
Area climate forecasters are warning of a robust (G3) geomagnetic storm, with an opportunity it might attain extreme (G4) ranges, because of a blast of photo voltaic materials heading straight for Earth. That might imply vibrant northern lights illuminating the evening sky as far south as Oregon, Illinois, and doubtlessly even deeper into mid-latitudes like Alabama and northern California tonight.
The incoming coronal mass ejection (CME) — an unlimited plume of photo voltaic materials — erupted from the solar within the early hours of Might 31, it’s at present hurtling in the direction of us at astonishing speeds.
“Our solar lastly goals for Earth!” Area Climate Physicist Tamitha Skov wrote in a post on X. However figuring out the precise time of when the CME will hit is tough as a slower photo voltaic storm in entrance would possibly maintain up the speedy photo voltaic storm behind.
“NASA mannequin predictions present a really quick #solarstorm travelling close to 1000 km/s that might hit Earth by noon June 1. A slower storm forward would possibly trigger a slight site visitors delay, however G4-levels by June 2 are doable,” Skov continues.

Geomagnetic storms are categorised utilizing a G-scale, which ranks their depth from G1 (minor) to G5 (excessive). The current geomagnetic storm watch that the U.K. Met Office Space Weather Operations Centre issued is rated a G4, indicating “extreme” storm circumstances. NOAA’s Area Climate Prediction Heart has additionally issued a G4-level storm watch with the prediction that G4 ranges could possibly be reached on June 2, with robust G2 circumstances nonetheless doable on June 3.
CME arrival at Earth is anticipated and a G4 Watch is now in impact for two Jun. CME arrival in a while 1 Jun might result in G3, with G4 potential elevated on 2 Jun, and as CME passage weakens, G1-G2 nonetheless doable on 3 Jun. Full story at pic.twitter.com/XWAb6H77KwMay 31, 2025
What’s CME?
CMEs are massive eruptions of plasma and magnetic subject from the solar; after they collide with Earth’s magnetic subject, they will trigger geomagnetic storms that set off auroras, generally seen a lot farther south than traditional. With this occasion, auroras could also be seen deep into mid-latitudes, making it a must-watch for northern lights fans!
When will the northern lights be seen?
The present predictions present the CME to impression Earth within the early hours of June 1 (UTC), so be sure you preserve your eyes on the skies as quickly because it will get darkish tonight! For the perfect probabilities of seeing the northern lights, head to a darkish location with an excellent view of the northern horizon.

The timing of the CME impacts can fluctuate, so it is essential to remain up to date on area climate alerts that present real-time forecasts based mostly in your location.
