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
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.

Side view from NASA's STEREO-A shows good Earth alignment in the ecliptic plane. High confidence of impact, but storm intensity uncertain. Models predict Kp 7-9 (strong-extreme), but NOAA & I think it'll be milder: Kp=6 Sep 1, Kp=7 Sep 2. Manage expectations!

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
Monday PM/Tue AM US forecast: Red line shows Kp=7 oval. Clouds high in NE/Midwest; better in West/North. Storm hits ~18:00Z Mon (ET daytime). "Show me" event—may underperform models. Visibility limited by clouds. Check our site for updates!
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.

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.
Where to see auroras: G3-G4 storm could light up Alaska, N. Canada, Iceland, Scandinavia, N. US states (WA, ID, MT, Dakotas, MN, WI, MI, ME). Southern Hemisphere: NZ, Tasmania, S. Australia. Look N horizon under clear skies. Track Kp on NOAA site. Possible live YouTube coverage!
