Breaking News: National Oceanic and Atmospheric Administration (NOAA) has announced a G3 Geomagnetic Storm is currently active.
It鈥檚 a beautiful, sunny day in the D.C.-area, weather-wise. But in the realm of near-Earth space and our planet鈥檚 magnetic field, a has been issued by NOAA for Levels G2 (Moderate) and G3 (Strong). The storms are forecast for Sunday and Monday and MAY produce aurora 鈥� possibly making visible in the U.S. Sunday night.
Aurora may be seen as low as Alabama and northern California.

Potential Impacts: Area of impact primarily poleward of 50 degrees Geomagnetic Latitude.
- Induced Currents 鈥� Power system voltage irregularities possible, false alarms may be triggered on some protection devices.
- Spacecraft 鈥� Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur.
- Navigation 鈥� Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur.
- Radio 鈥� HF (high frequency) radio may be intermittent.
Aurora may be seen as low as Pennsylvania to Iowa to Oregon.
Will the northern lights be visible from DC region?
The provides a two-day prediction of aurora. Northern U.S. states have a good chance of seeing aurora Sunday night but the D.C. region鈥檚 more southerly location makes it more 鈥渋ffy.鈥�
However, it is still worth taking a look to the North from a dark sky location with a clear Northern horizon to see if any aurora are visible. You may be up anyway to watch Sunday night鈥檚 penumbral lunar eclipse. The bright Full Worm Moon will also impact our ability to see dimmer aurora displays.

How to view aurora
Our best bet is to monitor the and sites such as and for updates. The current forecast shows the aurora will be visible to northern states. It will be worth taking a look to the North from a dark sky site with a clear horizon.
You might be able to detect some color in the sky if aurora are present, but they would likely be low on the Northern horizon. Wide field binoculars will help your search.
Use a camera or smartphone that can take exposures of several seconds 鈥� including using 鈥淣ight Sky鈥� or 鈥淟ow Light鈥� settings if your camera has them 鈥� of the Northern horizon. Steady the camera or use a tripod for best image results. The that your eyes did not.
The D.C. region had several aurora events visible in March, April and November 2023.

Space weather’s impact
With our terrestrial weather being such a factor in our daily lives here in the DMV, and frankly, the rest of the world, we are also directly affected by space weather which can produce a variety of events, including Sunday鈥檚 geomagnetic storm and the aurora.
Space weather, like our terrestrial weather, is caused by Earth鈥檚 interaction with our star, the sun. We know it will be there every new day and count on it for life-giving warmth and energy. We also have become accustomed to it being well behaved. What many people may not know is that our sun undergoes an that can affect space weather throughout our solar system.
is a 4.5 billion year old star that we have been monitoring since Galileo. Today, humans have a fleet of spacecraft that monitor the sun and space weather 24/7/365.
The sun is currently in and is progressing toward which is predicted to occur in July 2025. As the sun approaches solar maximum it and solar events which produce space weather events like Sunday鈥檚 Level G3 Geomagnetic Storm.
The sun had an episode of disturbed behavior in 1859 that if it were to occur today, could adversely affect us (if we were unprepared).
On Sept. 1, 1859, the sun experienced a solar storm episode that was observed by solar astronomer Richard Carrington that ended up bearing his name, “.鈥� This was a watershed event in solar astronomy and also the sun’s affect on the Earth as nothing like it has not been seen since 鈥� thankfully.
If a , the affect on modern society’s infrastructure could be potentially catastrophic, especially on the electrical grid which powers everything else. If you think this is unlikely or too to be true, I suggest you read the report by the .
Last year the sun had a very powerful , which fortunately for us, occurred on the .
You for 鈥渢raffic and weather together on the eights.鈥� Maybe now you will want to include a check on space weather too, as part of your daily routine.
