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.

Here are some images of Martian aurora taken by Mars orbiter .

"Under favorable solar wind conditions, discrete auroral events occur most evenings and may last for hours. MAVEN’s observations show that discrete auroras occur at an altitude of ~130 km in the atmosphere, where energetic charged particles cause CO, CO2+, N2, and atomic oxygen to glow."

The NASA Mars Atmosphere and Volatile Evolution mission has been studying Mars' atmosphere since Sept 21, 2014.

Looks like Mars rover Perseverance also decided to take a look at the sky last night.

Just a few stars shine in the image below taken using the SkyCam, an upward-facing camera located on the top deck of the rover.

This image was acquired on May 21, 2024 (Sol 1156) at the local mean solar time of 03:43:18.

The accuracy of some critical GPS navigation systems used in modern #farming have been "extremely compromised," a #JohnDeere dealership told customers Saturday. https://www.404media.co/solar-storm-knocks-out-tractor-gps-systems-during-peak-planting-season/ #aurora #sun #CME

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

Aurora forecast for 5/11/2024

@ai6yr if we're really lucky, it stays clear, and maybe.. MAYBE.. roofcam gets some glorious footage

@ai6yr Hopefully the skies stay clear and I can see them in the Netherlands! Too cloudy where I was last night and couldnt see it unfortunately. Would have been an amazing view

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

@ai6yr discussing this at work today. There's a threat to UAS systems that operate at ~1500m. and ops could be impacted.

We have a geochron setup across our radio room.

Wow... another data point in. G5.

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).

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.

"G5 (Extreme) Geomagnetic Storm Impacts

Power systems: Widespread voltage control problems and protective system problems can occur, some grid systems may experience complete collapse or blackouts. Transformers may experience damage.
Spacecraft operations: May experience extensive surface charging, problems with orientation, uplink/downlink and tracking satellites.
Other systems: Pipeline currents can reach hundreds of amps, HF (high frequency) radio propagation may be impossible in many areas for one to two days, satellite navigation may be degraded for days, low-frequency radio navigation can be out for hours, and aurora has been seen as low as Florida and southern Texas"

@ai6yr I'm just very happy that so far, we seem to have dodged the bullet there and are just getting pretty lights.

And now that it's getting dark here, looking forward to it...

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

An hour ago, I wasn't hearing Romania on 720 kHz; instead I had Iran 😮
Now, I do have Romania back on 720, but it's missing from 711 kHz; instead I have... Iran :v

630 & 963 Tunisia remain outstanding, as are 558 & 1170 from Slovenia (but not 549!). But NO Egypt, even on 864!

Bulgaria wasn't really heard throughout the evening on 576, but now it's fairly good.

A mindblowing thing is SBA Holy Quran sticking out on 873 (10kW) but down in the noise on 882 (100kW!)

It's really mindblowing how selective propagation can be in such extremely disturbed conditions 🤯🤯🤯
