A fast stream of solar wind flowing from a colossal coronal hole in the sun’s atmosphere could spark geomagnetic storms tonight and into the weekend (May 15 through May 17), potentially bringing the northern lights as far south as northern Michigan and Maine.
The strongest geomagnetic activity is expected between 11 p.m. and 2 a.m. EDT over the next few nights (0300-0600 GMT), which could trigger minor (G1) geomagnetic storm conditions according to NOAA’s Space Weather Prediction Center. Elevated geomagnetic activity could continue into May 17 as the fast stream of solar wind continues to buffet Earth’s magnetic field.
But remember, auroras are fickle creatures. Their visibility depends on several factors, including cloud cover, darkness and how Earth’s magnetic field responds to the incoming solar wind. Even during strong geomagnetic storms, sightings aren’t guaranteed.
How can I see the northern lights from where I live?
If you live in the northern U.S., head to a dark sky location as far from city lights as possible and look north as soon as the sky is dark. Smartphone cameras can help you capture faint auroras that may not be easily visible to the naked eye.
