- IanCal 4y agoFeels very sci-fi that I can go to a site and see a forecast of the space weather alongside handy graph of the current proton flux (on the homepage here https://www.swpc.noaa.gov/ https://www.swpc.noaa.gov/)
- 34679 4y agoSpaceweather.com is also worth checking out, for people into this sort of thing.
- FredPret 4y agoThere's also spaceweatherlive.com which is a dashboard. Feels like you're in Star Trek
- state_less 4y agoSure is beautiful when earth puts on her electric crown.
- dylan604 4y agoYour comment made me think of the images of Jupiter like this one: https://i0.wp.com/planetaria.ca/wp-content/uploads/2017/09/JupiterAuroras-NASA-TA.jpg https://i0.wp.com/planetaria.ca/wp-content/uploads/2017/09/J...
- state_less 4y agoThanks dylan604, it’s a wonderful image. I appreciate the people bringing us such clear images.
- PM_me_your_math 4y agoAnother website worth watching for this kind of thing is https://spaceweather.com/ https://spaceweather.com/
- j1mr10rd4n 4y agosome amazing auroral displays seen from tasmania over the last couple of nights https://www.abc.net.au/news/2023-04-24/strong-naked-eye-aurora-lights-up-tasmanian-skies/102258806 https://www.abc.net.au/news/2023-04-24/strong-naked-eye-auro...
- brabel 4y agoI could swear the sky was reddish as I went to bed last night, in Stockholm... it was rainy, but as I turned off all lights I noticed an unfamiliar, slight red tint. I thought that maybe it was some neighbour's light reflecting (probably was) but seeing the Tasmanian skies in the photos made me think it might've been Aurora as the color is very similar! I haven't seen anything in the news, but apparently some cities in Russia also reported Aurora sightings pretty far south.
- jve 4y agoAunty sent me pictures of this night aurora in Latvia... it is more southwards than Stockholm. I was amazed. And sorry that I didn't know I had to be up to see it too for the first time in my life... eh Color was Green/Purple
- flangola7 4y agoHow bad could this get?
- VLM 4y agohttps://www.swpc.noaa.gov/sites/default/files/images/NOAAscales.pdf https://www.swpc.noaa.gov/sites/default/files/images/NOAAsca... Its just a G3/G4 even we long term average about one a month. Get a couple G5 per decade, mildly more impressive.
- PM_me_your_math 4y agoNot really bad per-say. More like a passing space weather event. They are common events, especially when coronal holes turn to face Earth every 27 days or so. It can interfere with GPS timing. My neighbor had a GPS tracked geo-fence dog collar and it was behaving oddly yesterday.

- PM_me_your_math 3y agoThank you. I will email google and ask them to update spell check

- BulgarianIdiot 4y agoWhat's the actual impact on life, society and tech?
- Giorgi 4y agoPower goes out, so no protection from lasers and can't build new units.
- gumballindie 4y agoNone.
- weberer 4y ago>life No impact >society You get to see the northern lights >tech For a G4 storm, there may be some HF radio blackouts and power grid errors. https://www.swpc.noaa.gov/noaa-scales-explanation https://www.swpc.noaa.gov/noaa-scales-explanation
- syockit 4y agoThat'd better be the real northern lights, and not someone forgetting to turn off the stove after realizing the lunch is ruined.

- fartsucker69 4y agocant find the article anymore, but this was debunked
- the_mitsuhiko 4y agoI would be curious how you debunk this. It's evident that a bit flipped, cosmic rays are a known source of bit flips and a quite likely one compared to other factors. How do you debunk this?
- weberer 4y ago>Warning continues until 8:00AM EDT That's the current time. Looks like its ending now.
- tppiotrowski 4y ago> Published: Monday, April 24, 2023 17:26 UTC The forecast was updated at 1:00PM EDT so I believe it ends Tuesday at 8:00AM EDT
- vedosity 4y agoThere's a conflicting forecast here[0], that says it's decaying. The graphic for the "decaying" forecast says it's a forecast for 10am EDT. The forecast linked in OP says it's for 2am EDT, which is before the publish date for that forecast. So something's weird with the publish date listed on the forecast, I'm not sure I would trust that date. Seems like it's decaying, the decaying forecast is linked on their homepage and other space weather sites are forecasting it decaying as well.

- kaivi 4y agoI've always been hearing that solar flares and the resulting geomagnetic storms pose danger to hard drives and electronics. Is there any truth to it? Recently I've been building a server room, and naturally a question of EM insulation came up. If I were to protect my servers from this, I needed to wrap the room in a grounded mesh with holes of λ in diameter. What wavelengths am I protecting against? I couldn't find an answer online, perhaps because there isn't a mechanism which could flip bits or otherwise cause potential difference across my electronics, after a coronal ejecta reaches Earth. I can imagine how charged solar wind can interact with our atmosphere and cause voltage on long stretches of cable like telegraph or electricity lines, and consumers have surge protectors for this in multiple parts of the grid. Is there something that I've missed?
- joshspankit 4y agoYou can mitigate most of it by using ECC memory, a good line-filtering UPS, and some type of error-checking for reads/writes/at-rest. The last of the risk can be functionally eliminated by your off-site backup.
- egeozcan 4y ago> off-site backup Underground or at the other side of the planet or both?
- shagie 4y agoNot powered, but the next room over is acceptable for a solar flare. The issue would be that wires start getting induced current in them ( https://en.wikipedia.org/wiki/Geomagnetically_induced_current https://en.wikipedia.org/wiki/Geomagnetically_induced_curren... ) that arcs and shorts out the device. However, if you've got a backup tape there's nothing from the current that will flip the bits on the tape itself. There are good reasons to have the backup be off site (other physical calamities) - but the aurora isn't going to flip any bits on a backup. At worst, it will destroy the machinery from a surge from the grid and an extremely powerful one may destroy the machinery from arcing in the device itself (this would be extremely powerful)... but the media itself is fine.

- PM_me_your_math 4y ago<30 mhz is still somewhat of a mess. Most time stations are weak or unreadable. Ham bands are quiet. USAF rtty at 5mhz is loud but they have stations everywhere. At peak yesterday you could hear the curtains of ionized gas scatter radio signals on 3.330, 15.0 and 17 mhz. It sounds like a tremolo effect.
- clockworkhavoc 4y agoThe early stages of a solar micronova?
- SadWebDeveloper 4y agoThis is interesting around my area, there was a blackout at 7am to 7.30 am UTC-6 so could these be related?
- SirMaster 4y agoI've read stuff that a big solar flare could take out the whole electric grid and that it would take so long to restore it with parts we don't even have that things would basically devolve into chaos. https://emptaskforce.us/wp-content/uploads/2023/01/A-Call-to-Action-for-America-Revised-on-1-17-2023.pdf https://emptaskforce.us/wp-content/uploads/2023/01/A-Call-to...
- once_inc 4y agoIt could, but it is quite unlikely to happen. More plausible is a NEMP, in which an adversarial foreign state uses a nuclear explosion in the upper layers of the atmosphere to create a similar effect. A good fiction book in this regard is "One Second After" by William R. Forstchen. All governments of note have taken some precautionary measures; hardening critical machinery/infrastructure, but you can't plausibly do that for every bit of hardware in your country. Imagine the effect of seeing most cars dead on the street because the EMP took them out. Imagine not being able to call home, or having refrigerated foods.
- generalizations 4y agoIIRC, it's likely to happen about once every hundred years. Don't think it's actually that unlikely.
- fortenforge 4y agoIs it actually feasible to see the Northern Lights within driving distance of the bay area or should I not bother?

- Animats 4y agoSigh. Here's the word from the people in the PJM east coast grid control room. Event 103876 -- 04.23.2023 15:29 PJM-RTO Warning: Geomagnetic Disturbance Warning A Geomagnetic Disturbance Warning has been issued for 15:29 on 04.23.2023 through 08:00 on 04.24.2023. A GMD warning of K7 or greater is in effect for this period. Ended: 04.24.2023 08:00 (Eastern time) This was a non-problem. It never got above the "Warning" level. You can read the grid status live if you look through the PJM web site and figure out how to access the dashboard. There's also a long PJM training document on this that I linked the last time people got wound up about this.[1] [1] https://news.ycombinator.com/item?id=15201912 https://news.ycombinator.com/item?id=15201912
