The northern lights may placed on a present tonight and thru the weekend as ongoing geomagnetic storm circumstances pushed by turbulent area climate could push aurora farther south than standard.
Earth is presently reverberating from a photo voltaic storm influence that occurred in a single day on June 12-13, throughout which reasonable G2 geomagnetic storm ranges have been reached. A co-rotating interplay area (CIR) — a turbulent area within the photo voltaic wind wherein fast-moving streams collide with slower wind forward of them — can be on the way in which, with the results anticipated around June 14.
NOAA’s House Climate Prediction Heart (SWPC) has issued a reasonable (G2) geomagnetic storm watch for June 14 because of the incoming solar wind from a big Earth-facing coronal gap. The U.K. Met Office echoes this forecast, predicting reasonable (G2) geomagnetic storms on June 13-14, with exercise anticipated to say no to unsettled ranges by June 15-16.
What does this imply?
A G2 storm can shift the aurora oval — the ring-shaped zone the place auroras usually type — farther south, permitting skywatchers throughout components of the northern U.S. an opportunity to catch a glimpse of the elusive lights, climate and darkish skies allowing. Geomagnetic storms are ranked utilizing a G-scale, which ranges from G1 (minor) to G5 (excessive).
States that might see auroras tonight
Beneath, we now have listed 18 states that seem both totally or partly above the attainable view line for auroras tonight, in keeping with NOAA’s Space Weather Prediction Center. They’re ordered from most certainly to least possible based mostly on their proximity to the middle of the auroral oval and the way a lot of every state is inside or close to the view line.
Take note, auroras are fickle. Generally they present up a lot farther south than anticipated and different instances they do not seem in any respect. Many circumstances must align for the proper show.
- Alaska
- Montana
- North Dakota
- Minnesota
- Wisconsin
- Michigan
- South Dakota
- Maine
- Vermont
- New Hampshire
- Idaho
- Washington
- Oregon
- New York
- Massachusetts
- Connecticut
- Rhode Island
- Wyoming
Viewing circumstances additionally rely on extra than simply geomagnetic exercise. Cloud cowl, gentle air pollution, and the transient summer season night time can all have an effect on visibility.

How can I see the northern lights from the place I reside?
If you end up in one of many 18 states listed above (or just need to attempt your luck) head to a darkish, north-facing spot away from metropolis lights. As we method the summer solstice on June 20/21, nights are rising shorter, so your finest window for viewing could also be within the early morning hours, round 1 to 2 a.m.
Involved in monitoring area climate and understanding when and the place to identify auroras? Obtain a space weather app that gives forecasts based mostly in your location. One possibility I exploit is “My Aurora Forecast & Alerts,” out there for each iOS and Android. Nevertheless, any related app ought to work properly. I additionally use the “House Climate Stay” app, which is available on iOS and Android, to get a deeper understanding of whether or not the present area climate circumstances are favorable for aurora sightings.
