A. This is awesome: "AURORAS OVER THE GRAND CANYON: You know a solar storm is big when ... it produces auroras over the Grand Canyon. Brian A. Klimowski photographed the rare display on May 11, 2024: "This was just the afterglow of a more intense G5 storm on May 10th, but still so beautiful...

Wow! for the photos above etc. ... News just came in. The monster sunspot didn't stop there: Tue May 14, 2024 THE BIGGEST SOLAR FLARE OF THE CURRENT SOLAR CYCLE: Earth-orbiting satellites have just detected the most intense solar flare of the current solar cycle (so far)--an X8.7-category blast...

Thanks for painting those pictures ... Cloud patterns can do a lot of things (so it could be luck too) but (since clouds have electric charge & move accordingly) there could be an effect too (that I haven't heard of myself) consistent with the dynamics of the auroras & geomagnetic storms (?)...

Tue May 13, 2024 "THE BIG STORM IS OVER: NOAA forecasters say that the storm is really over now. There's no chance of additional G5 activity this week because all the big CMEs have already come and gone. However, relatively minor G1 or G2-class storms are possible on May 13th in response to a...

Ok, thanks Greg ! [I also edited my note there to indicate the deletion of those 4 links] Also thanks @Tom.G and the rest of the participants for pointing this out.

Edit time has elapsed. I always remove a lot more spacer images that you know. The problem is not in the table but in the links (only those 4). Waiting for Greg's reply first. All other links work. It's the first time for me to see that, but from the site they open just fine. Deleting the table...

Important Note regarding the previous post above: the 4 links ["Europe", "USA", "New Zealand", "Antarctica"] in the "Current Auroral Oval" display diagram can only be opened (giving a modified diagram on your screen in a live manner) by visiting the original site spaceweather.com ... P.S. edit...

Only those 4 links (for that post) about "USA", "Europe", "New Zealand", "Antarctica" ... [aurora forecast diagram display - "Current Auroral Oval"] – because they are indeed relative and internal [diagrams] in the original spaceweather.com site - [see also "3)" below ...]. 1) All other copied...

A. "AURORAS IN STRANGE PLACES: The historic geomagnetic storm of May 10-11, 2024, produced auroras across Europe, Asia, Japan, Mexico, and all 50 US states--even Hawaii. Hundreds of millions of people saw the colored lights for the first time in their lives. No photographer could have planned to...

A) Latest predictions (still May 12 ...): " THE STORM IS OVER, BUT... This weekend's extreme geomagnetic storm is over, but there might be a last gasp. NOAA forecasters are currently predicting a return to severe (G4) conditions on May 12th when one or more CMEs might hit Earth's magnetic...

I had this in my files to post (regarding a sungrazing comet - see ahead) - goes back to eclipse time - really interesting, take a look (posted on spaceweather.com on April 10 & 11, 2024) : " THIS COMET DID NOT SURVIVE THE ECLIPSE: Astronomer Karl Battams of the Naval Research Lab predicted...

The "monster" sunspot on limb very soon - extreemely high speed [but very low density] solar wind right now ... - take a look: "Solar wind speed: 906.2 km/sec density: 0.41 protons/cm3 more data: ACE, DSCOVR Updated: Today at 0945 UT X-ray Solar Flares 6-hr max: M2 0552 UT May12 24-hr: X1 1144...

Today, May 11 : (... & a few minutes before posting this, the Solar Wind reached/was 784Km/sec or more) " THE STORM IS NOT OVER: A CME hit Earth's magnetic field on May 10th, sparking the biggest geomagnetic storm in more than 20 years--an extreme (category G5) event. It is subsiding now...

Wow! great photos & witnesses of the storms ... Unfortunately, completely overcast in my location. Kp index (index for auroral activity) reached 8 early this morning ... (was already 7, high enough, yesterday). wow ... lucky ... - please do! Note: ranges: G1 to G5 [storm category/intensity]...

Update for the Storm (May 10, 2024): A) "The ongoing storm is producing low-latitude auroras in the southern hemisphere. Ken James sends this picture from the Snake Valley Observatory in Victoria, Australia: "The red, yellow and green colours were easily visible to my naked eye," says James...
