Space weather physicist sharing northern lights forecasts and solar physics updates. Local forecasts for your area: https://auroraforecasttonight.com
NEW: We just shipped a fully 3D, scrollable aurora visibility forecast: drag to rotate the globe, scroll to zoom, watch the aurora oval expand in real time as geomagnetic activity climbs. Looking for beta testers 👇 auroraforecasttonight.com
Our flagship product is online today after a few weeks of testing. If that solar storm you were waiting for doesn’t end up arriving, our model won’t exaggerate the visibility forecast. Be sure to sign up for exclusive free access at auroraforecasttonight.com
So, are you going to see the aurora tonight? It's a great question. Type in your zip or postal code and find out for your exact area, completely free. We've factored in the clouds too 🙂 auroraforecasttonight.com
Aurora Forecast Tonight | Northern Lights Forecast for Your Exact Location
The only aurora forecast that checks the clouds too. We combine the aurora forecast with your local cloud cover, so you're not left guessing whether you'll actually see it. Enter your zip code to see ...

To my SWW followers: I’ve started a new account/website focused on explaining the latest Long COVID research in plain language, if you're interested, as this is where I’m needed right now. I’ll be posting space wx content less frequently here. Thanks for all of the continued support. long-covid.org
Thank you for your aurora reports! We had nearly 2,000 photos of aurora sent in from 12 countries across the world and 49/50 U.S. states as the Northern Lights made another widespread appearance on November 11 2025. View our interactive map, courtesy Hunter Hurley, here: hhwx.me/projects/aur...

Nearly a full flight of northern lights IAD->SEA. Just a small selection of photos, best I could do out of a plane at 35k ft with an iPhone @capitalweather.bsky.social @spacewxwatch.bsky.social

Incoming CME alert! A fast-moving solar storm (~1300 km/s) blasted from the Sun yesterday—Earth-directed halo type. Low mass, so moderate-strong impact expected. Arrival: Afternoon Sep 1 (Labor Day). Monitoring closely! #Aurora #SpaceWeather
Strong M8-class flare occurring now, initating a very large-scale eruption on the Earth-facing solar disk which is at least likely partially Earth-directed. A full halo CME is expected.
Incredible eruption associated with today's X1.2-class flare off the western limb. Imagery of the solar storm is still coming in, but expecting it to look like a partial halo. The storm itself will probably miss Earth, but energetic particles are currently streaming towards Earth

AURORA/CLOUD FORECAST TONIGHT: A significant CME has arrived and geomagnetic effects are likely this evening. We may choose to move our auroral line farther south this PM, so stay tuned to our page for details. The red line represents southern extent of aurora visibility on the northern horizon.
A strong interplanetary shock (solar storm) arrival near Earth is now ongoing, per ACE/DSCOVR satellites. Moderate to strong geomagnetic storms possible this evening
A Moderate (G2, Kp=6) Geomagnetic Storm Watch has been issued by NOAA/SWPC for 16 April due to anticipated CME impacts.
TUESDAY NIGHT (4/15) AURORA FORECAST: A pair of filament eruptions occurred today on the Earth-facing disk, both of which may potentially be Earth-directed. The first appears to be more Earth-directed in EUV imagery, but the second appears to have a wider extent, indicating likely Earth-directedness
A gigantic eruption occurred today, and it was one of the significant eruptions in recent memory. I think it's safe to say that we dodged an extreme geomagnetic storm here. If all of the power in today's eruption could be harnessed, it would probably power all of humanity for over 100 billion years
TONIGHT: We're seeing the pileup out ahead of our anticipated coronal hole high speed stream.
Moderate geomagnetic storms expected later in the Zulu day as Earth connects to this high speed stream, potentially lasting 2 days or more. Yep yep yep.
If you could take any one person, celebrities included, on a 7-day, all-inclusive Northern Lights adventure and tour, complete with a cabin that has a crystal clear view of the sky from your bedroom... who would it be?
The CME we were expecting late last night still hasn’t reached Earth yet—I’ll keep you posted if anything changes! In the meantime, thanks for sticking with real space weather experts and not the "armchair" meteorologists who were confidently predicting auroras deep into the U.S. last night! 😉
(1/5) March 22 09:15pm ET: The solar wind is a bit enhanced still from yesterday's CME arrival, but magnetic field is rather low and stable and solar wind velocities are less than 500 km/s.
Did you see #aurora last night? Please let us know! Meanwhile, a fast Earth-directed CME followed shortly after by the effects of a large coronal hole will almost certainly bring more geomagnetic storms to Earth in the next 1-3 days. More deets below:
That is a very large coronal hole--a patch of open magnetic field lines on the Sun which stream out fast solar wind known as a "high speed stream". Effects from it could start at Earth as soon as late on March 24th and will probably persist for two days or more. #spacewx
