Remember the X8.7 solar flare on May 14, as sunspot region 3664 was rotating away from earth?

The #CME from that flare reached Mars on May 19. Mars rover Curiosity took some nighttime images of the Martian sky hoping to catch an #aurora.

#Mars lacks a global magnetic field, hence Martian aurorae are not concentrated at the poles, but instead appear as a “global diffuse aurora” associated with Mars’ ancient, magnetized crust.

Not clear if Curiosity succeeded.

Knocks Out ' Systems During Peak Planting Season
The accuracy of some critical GPS navigation systems used in modern have been "extremely compromised," a dealership told customers Saturday. https://www.404media.co/solar-storm-knocks-out-tractor-gps-systems-during-peak-planting-season/

Hmm, maybe no aurora down here tonight. Or maybe still? #SpaceWeather #CME #aurora

Aurora forecast for 5/11/2024

It's not quite as active now, but the aurora was wild earlier. This was just a simple night lapse on my Hero11 - we could see colors and pillars with the naked eye, but the camera is next level

So far, no power outages (or at least, not any noticeable in US) due to the solar storm, per poweroutage.us (outages in Florida are due to wind/tornadic activity earlier). #SolarStorm #CME

Aurora from the Chicago suburbs. Need to color correct these, but was too excited. First time I've seen the aurora and it was over the entire sky! Incredible!!

The aurora borealis. Pink, purple, blue, and green colors in the sky.

Seeing secondhand reports of aurora being visible in South Florida (Miami). Anyone out there able to confirm? #Aurora #FLwx #SpaceWeather

I've got a question.
Is the line around the equator here, an artifact of this rendering or is something else going on?

I think I’m going to plug my computer back in. I don’t see any signs of weird power dips or anything, and it’s annoying just using my phone. Hopefully we don’t get anything that the surge protectors won’t stop, and stay at “pretty lights in the sky tonight” rather than apocalyptic

EEEK G5 #SolarStorm. Somehow not a Carrington Event let’s hope it stays that way. Most extreme solar storm in years, though

Better go unplug my computer etc just in case

Czechia is now back, but instead, am losing Romania, even on 756 kHz, which is usually a powerhouse signal 😮
More Romania attenuation makes other signals clear: 630 Tunisia sounds almost like a local! On 531, Radio Algeria International has the frequency all to itself -- well, it's weak too, revealing more NDBs on 527 & 535 kHz.

Only just starting to hear BBC on 693 kHz. 648 Caroline is stronger.

And Lithuania has finally ceded way to 1386 Greece - now w/ audio!

Getting more signal from Spain on 738 kHz than from much closer Romanian transmitters on 711 & 720 😮

In fact, (most of) Romania is so heavily attenuated that it revealed an NDB on 718 kHz, callsign BX, in Belgorod🇿☠ #CME #Aurora

Bz latitude went as far down as -46 @ 1735-1740z 😱😱😱 and I've never seen it fall below -20 😱 #CME #Aurora

Not to mention there's been NO observations since 1952z, the whole 9 minutes as I type this.

Really, this is the 1st time ever that I see a RED colour on those SWPC indicators 😱😱🔴 #CME #Aurora

It's an hour past sunset, yet #mediumwave looks as if it was more like an hour before sunset...

Very poor signals, only few listenable ones.

BUT the most shocking thing is 1035 Radio Eli 🇪🇪 is COMPLETELY MISSING, and I'm beginning to lose Lithuania 🇱🇹 on 1386 (it's head-to-head w/ an off-freq Greek #pirate) -- on an unterminated SuperLoop, not a KAZ with a null on them 🤯

No Southern enhancement meanwhile; no Tanzania after TWR s/off on 1377, & no trace of Djibouti on 1116.

Aurora Forecast for tonight! #aurora #SpaceWeather #CME

NewScience101, to science

U.S/CA Keep an eye on the NOAA geomagnetic activity tracker Tonight-Sunday.
Folks as far south as Alabama, U.S may be treated to an #aurora.
In fact, with 5 CMEs headed our way, everyone across the globe should keep an eye on the night time sky.

Be sure to tag us to share your pics! xo

NOAA SWPC video of the solar flare that spawned CMEs... Expected to cause some great aurora activity, potential to also cause other mischief (mostly in space/high latitudes). Though it will probably wipe out ham radio too this weekend. #CME #spaceweather https://www.youtube.com/watch?v=-dr2BIlDGDk

Incoming! A severe G4 Geomagnetic Storm is expected to arrive around 02:00 UTC Friday night / Saturday morning.

At least 5 Coronal Mass Ejections took place over the past 24 hours, directed towards Earth. These originated from a large and magnetically complex sunspot cluster (NOAA region 3664).

There is potential for disruption of communications, the electric power grid, navigation, radio and satellite operations.

And bright auroras as far south as Alabama!

It's happening! Aurora sightings being reported from Europe.
Just search for "aurora" on twitter or Mastodon.
