The Northern Lights may be visible in the U.S. this weekend, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center, which is predicting aurora may be potentially glimpsed from 10 U.S. states on Saturday, June 7.

It comes in the wake of a coronal mass ejection — a cloud of super-charged particles — departing the sun on Tuesday, June 3. A CME takes a few days to travel from the sun to Earth, but exactly when it arrives is always difficult to accurately predict.

“By mid to late on 07 Jun, a glancing blow from the 03 Jun CME is expected to cause an enhancement in magnetic field parameters,” reads a forecast from NOAA. “By mid to late on 07 Jun, G1 (Minor) storm conditions are likely with the arrival of the 03 Jun CME.”

It all comes just days after a rare G4 geomagnetic storm that lit up June skies worldwide last weekend, with bright auroras across the world after a “fast halo CME” arrived. There is currently an Earth-facing coronal hole on the sun — a large hole in its atmosphere where magnetic fields can escape — that is creating a fast-moving and turbulent stream of solar wind to move in the direction of Earth.

A G1 geomagnetic storm on Saturday, June 7, may have aurora visible from northern U.S. states. “Migratory animals are affected at this and higher levels; aurora is commonly visible at high latitudes (northern Michigan and Maine),” according to NOAA, though its aurora view line has the phenomenon potentially visible from 10 states.
