Northern Lights Tonight: Best States to See Aurora Forecast 2024

A significant solar event has increased the likelihood of aurora borealis visibility across multiple United States states, with forecasters predicting active displays may be observable from locations as far south as Massachusetts under clear sky conditions.

The Space Weather Prediction Center is issuing aurora viewline predictions for tonight and tomorrow night over North America, showing the southern-most locations from which observers may see the aurora on the northern horizon. The forecast indicates active aurora activity, with displays potentially visible overhead from Utqiaġvik to Anchorage and Juneau in Alaska, according to the Geophysical Institute.

News outlets report that the biggest solar flare of the year has created conditions favorable for northern lights visibility across approximately 10 states. The Worcester Telegram noted that Massachusetts might be among the states able to observe the phenomenon tonight.

How Aurora Forecasts Work

The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center uses the OVATION model to predict aurora intensity and location. This empirical model, developed at the Johns Hopkins University Applied Physics Laboratory, forecasts the maximum geomagnetic activity between 6pm and 6am US Central Time.

The aurora viewline represents a prediction of where the northern lights may be visible. The brightness and location of the aurora is typically shown as a green oval centered on Earth’s magnetic pole. When the aurora is forecast to be more intense, the green ovals turn red on the prediction maps.

According to NOAA, aurora can often be observed somewhere on Earth from just after sunset or just before sunrise. The aurora is not visible during daylight hours. The phenomenon does not need to be directly overhead but can be observed from as much as 1000 km away when the aurora is bright and if conditions are right.

What Creates the Northern Lights

The aurora borealis and aurora australis are natural light displays caused by charged particles from the sun colliding with Earth’s atmosphere. When solar activity increases, such as during significant solar flares, more charged particles reach Earth’s magnetic field, creating the conditions for visible aurora displays at lower latitudes than usual.

Real-time aurora forecast maps powered by NOAA data show aurora probability predictions ranging from 0% to 100%, along with Kp index measurements and solar wind conditions. These tools help aurora hunters determine whether conditions are favorable for viewing in their specific location.

Viewing Conditions and Timing

For those hoping to observe the northern lights tonight, clear skies are essential. The Geophysical Institute forecast specifically notes that active auroral displays may be visible if skies are clear. Cloud cover remains one of the primary obstacles to successful aurora viewing, even when geomagnetic activity is high.

The NOAA aurora viewline images are updated continuously, with the transition when tomorrow night becomes tonight occurring at 12:00Z. This timing falls within an hour of the end of the 6pm-6am Central Time window used to define night for forecasting purposes.

Short term forecasts covering approximately 30 minutes along with the last 24 hours of activity are available on the Aurora 30 Minute Forecast page. SWPC also maintains an Aurora Dashboard that collects products and information from across their website for comprehensive space weather monitoring.

States With Increased Visibility

BBC Sky at Night Magazine reported on increased aurora activity and identified US states most likely to see Northern Lights displays. While the specific list of 10 states varies by report, Massachusetts has been specifically mentioned as potentially able to observe the phenomenon due to the significant solar flare activity.

Alaska remains the most reliable location for aurora viewing in the United States, with forecasts indicating active displays may be visible overhead from Utqiaġvik to Anchorage and Juneau. Lower 48 states may see the aurora on the northern horizon when geomagnetic activity reaches sufficient intensity.

Interactive aurora maps allow observers to check real-time forecasts and see if the Northern Lights are visible in their area. These maps display aurora probability percentages and help viewers understand their chances of successful observation based on their geographic location and current space weather conditions.

Space Weather Impacts

Increased geomagnetic activity that produces visible aurora can also affect other systems. The Space Weather Prediction Center monitors potential impacts on electric power transmission, HF radio communications, and GPS systems during periods of heightened solar activity.

For aurora hunters planning to observe tonight’s displays, checking multiple forecast sources provides the most complete picture of viewing conditions. The combination of NOAA’s official predictions, real-time monitoring tools, and local weather forecasts offers the best chance of successfully observing this natural phenomenon.
