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...

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
1215
Space Weather Watch @spacewxwatch.bsky.social · 31/05/2025
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.

Space Weather Watch @spacewxwatch.bsky.social · 13/05/2025
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.

Space Weather Watch @spacewxwatch.bsky.social · 15/04/2025
A strong interplanetary shock (solar storm) arrival near Earth is now ongoing, per ACE/DSCOVR satellites. Moderate to strong geomagnetic storms possible this evening

Space Weather Watch @spacewxwatch.bsky.social · 13/04/2025
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.
1202
Space Weather Watch @spacewxwatch.bsky.social · 25/03/2025
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.

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:

Space Weather Watch @spacewxwatch.bsky.social · 21/03/2025
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

Space Weather Watch @spacewxwatch.bsky.social · 21/03/2025
CME ARRIVAL: Minor to moderate (Kp=5-6) geomagnetic storms likely this evening with strong storming possible (Kp=7) as a strong magnetic field enhancement is observed at solar wind spacecraft at ACE/DSCOVR following the passage of a solar coronal mass ejection

Space Weather Watch @spacewxwatch.bsky.social · 19/03/2025
We're still awaiting a CME arrival during the second half of tomorrow, but meanwhile, some disturbance is passing by the near-Earth environment... folks in Canada and the northern fringes of the U.S. could be in for aurora views tonight, potentially... let us know if you see anything?

Space Weather Watch @spacewxwatch.bsky.social · 17/03/2025
LIKELY EARTH DIRECTED SOLAR STORM THIS EVENING: You can see a solar storm, or coronal mass ejection (CME) being ejected to the north and east (up and left) in before and after views tonight from NASA’s Stereo Ahead spacecraft, which is about 30 degrees upstream of the Earth-Sun line.

A minor geomagnetic storm is ongoing this evening as Earth connects to a coronal hole high speed stream and should persist into the overnight--perhaps some aurora chances for those at higher latitudes tonight, and maybe even some folks in the northern fringes of the U.S. too!

TOTAL LUNAR ECLIPSE EARLY FRIDAY AM: Tell your friends! The Moon will turn a brilliant shade of red early on Friday morning during a total lunar eclipse where long wavelength red light will pass through the edge of Earth’s atmosphere and bend toward the Moon.

First space weather summary sent on Friday night was a success, with a moderate (Kp=5.67) geomagnetic storm occurring throughout today thanks to effects from a coronal hole. Updates will be sent out Mon, Weds, and Friday--be sure you're on the list to receive them! www.patreon.com/c/spacewxwat...

Space Weather Watch @spacewxwatch.bsky.social · 08/03/2025
STORMS LIKELY THIS WEEKEND: We're (unofficially) calling for a 90% chance of a minor geomagnetic storm (Kp=5) in the next 72 hours due to anticipated coronal hole high speed stream effects.

HAPPENING NOW: X2.0-class flare in progress from the Sun's western limb. A significant solar storm (coronal mass ejection) in association with this flare is likely. A radiation storm at Earth is also possible. #spacewx

NEW: Probability of “city-killer” asteroid YR4 impacting Earth on December 22, 2032 now increased to 3.1% (now 1 in 32), per NASA.
99017
Space Weather Watch @spacewxwatch.bsky.social · 18/02/2025
The asteroid is approximately 220,000,000 kilograms or 440,000,000 pounds, about as heavy as a very large cargo ship—moving at 17 kilometers (11 miles) per second.

Odds of “city-killer” asteroid YR4 impacting Earth now increased to 2.6%, per NASA Just about equal odds of betting on a single number straight on one spin of American (double zero) roulette

Space Weather Watch @spacewxwatch.bsky.social · 10/02/2025
(1/4) The 2024 YR4 asteroid is currently a 3 on the Torino scale (code yellow), an integer scale from 0 to 10 for categorizing the likelihood and consequences of a potential impact event.

A minor geomagnetic storm is ongoing now due to effects from a coronal hole high speed stream. Folks at high northern latitudes and possibly the northern-most fringes of the U.S. may potentially see some aurora tonight! If you see anything, be sure to let us know!
