Space Weather Solar Flare Alert: A strong X4.0 flare from AR4274 peaked at 08h30 UT 14 Nov. An R3 radio blackout affected south-eastern Africa, Madagascar and Indian Ocean regions. AR4274 is near the west limb so any CME would not be earth-directed. Stay tuned for updates. #spaceweather #g7izu

Space Weather Geomagnetic conditions appear to have fully calmed down now. The solar radiation storm has also ended.

Space Weather The CME from the X5.1 flare on the 11th arrived last night just after 20h UT. It had a strong northward Bz (magnetic) component. This initially cancelled out the Earth's magnetic field, so the CME impact and following couple of hours were pretty dull until the Bz finally swung south j

Welcome! Just a quick note to say that the solar storms over the last couple of days have brought me a lot of new followers on Mastodon, so just a note to them to say "welcome to the feed", and I hope you enjoy it!

Space Weather The solar radiation storm has now reduced to S1 (Minor) level at 23h20 UT. Geomagnetic storm conditions are continuing with so far a few effects at high-latitudes (minor-moderate substorms at Kiruna).

Space Weather AURORA ALERT We have a similar pre-cursor signature of the Goes 18 satellite crossing the helio-sheath as seen yesterday as the Earth's magnetic field is compressed ahead of the CME. The storm is almost here! #spaceweather #aurora #g7izu

Space Weather The CME from yesterday's X5.1 flare is inbound and on final approach. There are various predictions for its arrival time, but most are suggesting between 18h and 21h UT today (12 Nov).

Space Weather The strong geomagnetic storms have triggered a "Grid Emergency" in New Zealand. Transpower is acting to protect its power grid by shutting off key sections to prevent damage. Some areas of New Zealand may lose power temporarily.

Space Weather G5 Geomagnetic Storm! You'll start seeing hundreds of pictures all over the news today. Bright pink and red aurors have been seen down to very low latitudes (for those without heavy cloud cover 😫). This one is from West Cork in Ireland. #spaceweather #aurora #g7izu

Space Weather Comment seen in a space weather group chat in a forum with space weather professionals: "Holy moly!" The G3 storm threshold has been reached. More is to come. 2000nT deflection noted for the Kyoto aurora electrojet plot. Wow! #spaceweather #aurora #g7izu

Space Weather Incoming! (also it's not the apocalypse, it's just a light-show for the most part!)

Space Weather A further shock has been detected at L1 so this may be the CME proper, arriving at Earth in around an hour.

Space Weather The CME has reached L1 with a strong southward Bz component. Aurora watchers get ready for a good show in around 45-60 minutes! It looks like a strong shock is incoming. #spaceweather #aurora #g7izu1

Space Weather Incoming geomagnetic storms: Effects from the X flares on 9 & 10 Nov should arrive at Earth at around 20h UT this evening (11 Nov), according to Nasa's WSA-ENLIL Solar Wind Prediction model.

Space Weather An S2 solar radiation storm is now in progress. The scale runs from S0 to S5. Possible effects at S2: Biological: Passengers and crew in high-flying aircraft at high latitudes may be exposed to elevated radiation risk. Satellite operations: Infrequent single-event upsets possible.

Space Weather Solar Flare Alert: An X5.2 flare from AR4274 peaked at 10h04 UT 11 Nov. A strong R3 affected southern Africa. A type II radio emission was observed. Electron and proton fluxes are above warning levels.

Space Weather Major solar flare in progress >X5. Standby for updates #spaceweather #g7izu

Space Weather The Solar XRay flux has now reduced below M-level following a long duration X1.2 flare from AR4274. An S1 solar radiation storm is in progress. An electron storm is now in progress. Electron storms can affect space hardware due to charging of electronic components. #spaceweather

Space Weather Summary: A strong X1.2 flare from AR4274 peaked at 09h18 UT 10 Nov. The flare was of long duration and has still not fallen below M-level at 12h20 UT. Type II, type IV radio emissions and a 10.7cm radio burst were observed.

Space Weather A strong X1.2 flare peaked at 09h18 UT 10 Nov. An R3 radio blackout affected Africa, Middle East and Indian Ocean regions. The flare is still decaying. #spaceweather #g7izu

Space Weather Solar flares alert: A large flare is in progress, now >X1 with am R3 radio blackout. Stay tuned for updates. #spaceweather #g7izu

Space Weather A large X1.8 flare peaked at 07h35 UT 09 Nov. A type II emission and 10.7cm radio burst were observed. A large halo CME can be seen on Lacso C2 imagery. The CME is not squarely Earth-directed,but it will be enough to cause significant geomagnetic effects in a few days.

Twelve months ago, I got my amateur or “ham” radio licence. It’s the best thing I have done in recent years. #amateurradio #hamradio andrewwoodward.net/2025/11/09/o...

Space Weather All of a sudden it looks like space weather has taken the night off! No strong flares for 14 hours, and the solar wind has calmed down enough for "QUIET" geomagnetic conditions to be reported across the board. A calm before a storm, perhaps? We shall see.

Space Weather Multiple CMEs have started to block galactic cosmic rays in a process known as a Forbush Decrease. Cosmic rays are currently down around 7% on the longer-term level. #spaceweather #forbushdecrease #g7izu

Space Weather Solar flare/CME alert: An M1.8 flare peaked at 07h10 UT 07 Nov. Type II and type IV radio emissions were observed, indicating the release of another CME from AR4274. As AR4274 turns more towards Earth, CMEs will start to have more geomagnetic impact. #spaceweather #g7izu
