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.
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!!
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 #CarringtonEvent
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!)
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!
NO signal from Country Radio on both 639 & 954 kHz, and Radio Dechovka is also missing on 792, not to mention 1260 kHz.
Also lost most of Romanian txers: 630 has Tunisia instead of Timisoara, and 711 & 720 have gone silent - together with the naZi NDB on 718.
Totally lost 1386 kHz from Viesintos🇱🇹 - and even 1557 Sitkunai, some 200km closer. 666 Sitkunai too, still going strong, but I guess that's groundwave...
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.
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.
