A solar storm is expected to cause geomagnetic conditions that may push the auroras farther south than usual, according to the National Oceanic and Atmospheric Administration (NOAA). This means northern lights could be visible from Alaska to Connecticut tonight. The high-speed solar wind is putting pressure on Earth’s magnetic field, fueling the storm.
Forecasts predict strong geomagnetic storm conditions with a possibility of severe conditions due to elevated solar winds and an Earth-directed coronal mass ejection (CME). The NOAA Space Weather Prediction Center predicts that the Kp index will peak at 4.67 over the weekend.
For those hoping to catch a glimpse of the northern lights, Alaska has the highest chance of seeing them tonight. States such as Michigan, Maine, and Vermont are also likely to see auroras if G3 or G4 storm levels are reached.
Aurora chasers can use space weather apps that provide forecasts based on their location to track the best viewing times. It’s essential to find a north-facing vantage point with minimal light pollution for the best views.
The window of darkness for observing northern lights is shrinking due to the summer solstice, so early morning hours around 1 and 2 a.m. might be the best time to spot auroras.
