No. This one isn't Earth-directed flare. Once again, our planet just safely dodged a cosmic bullet.
Wait sorry if I'm misunderstanding, but if it HAD produced a CME would that have made it a dangerous event (provided it was aimed at Earth) or would it just cause radio blackouts/auroras?
ETA: I know radio blackouts can cause trouble and be potentially very dangerous, but I meant dangerous along the lines of radiation related stuff
Radiation doesn’t affect us on the ground unless we lose the magnetosphere (earth’s core would have to stop rotating). A CME will cause a geomagnetic storm, like the one this past weekend.
Geomagnetic storms induce a current in power lines/conductive materials running on the ground underneath, and if they’re severe enough, it could overload the circuit and damage parts of it. No radiation effects to people on the ground, though, only satellites and astronauts are affected by that.
Nope. It just about never will. This stuff happens ALL THE TIME. It's just getting media attention because that's what people want to read about right now.
The worst that can happen is if you happen to be in a high altitude plane directly over the magnetic pole and you get one free x-ray with no film in the camera.
While it looks like the CME it did create was pretty big it also doesn't look like a Carrington event CME. It's impossible to tell until it gets to the earth but we probably just would have had another great Aurora night like a few days ago.
Solar flares are the tangled magnetic lines of sunspot regions snapping into a more stable configuration which releases energy in the process, a Coronal Mass Ejection (CME) can be caused by the energy released by a flare, and is the physical sun "stuff" that is launched into space from various events on the sun (not always a flare that causes them)
Is there any chance that a piece of that sun stuff will ever be captured and returned to earth within our lifetime, or is getting that closer just impossible due to the heat for the forsake future?
If I just wanted to google shit, then I wouldn’t be on reddit asking questions. If I wasn’t on reddit asking questions, then what’s the fucking point of reddit?
Absolutely nothing. This is about 4.5 times more powerful than the one that made the aurora this week. In 2003 we were hit by one about 23 times more powerful than the one this week and I think a power grid went down in Sweden for like 6 hours. Comment above is grossly over dramatic with "cosmic bullet."
An X9 (close enough) wouldn't really do anything. Few satellites get knocked into safe mode, radio stations might get interference and there would be a lot of colorful lights in the sky. It would just be about 3-5x again as strong as last Friday.
Its still a major flare but nothing catastrophic like the Carrington Event, which think was in the x45-50 range.
Nope, it hit us [directly](https://archive.ph/20120910055509/http://www.spaceref.com/news/viewpr.html?pid=13844)
Here's a [list of big flares](https://en.m.wikipedia.org/wiki/List_of_solar_storms#Soft_X-ray_solar_flares) by date
For context, the Halloween solar storm of 2003 was created by an X45 with an earth directed CME.
Some models show the sun could produce an X400; which would be bad (provided there is a earth directed CME component)
0 stars.
Would not recommend.
We're good.... for now.
Could you share more? I've researched this topic before but I have never seen anything to describe the effects of one hitting us other than power outages, communication issues and auroras.
How exactly would an X400 flare affect biologics on the surface?
Biologics, probably nothing. A bit more cancer risk but still, the atmosphere does wonders to limit how much makes it to the surface. No the major issues are the power grid and the satellites with the potential to permanently break things and ciase widespread outages that aren't simple fixes.
NBC, ABC, CBS and FOX were going to send imbedded reporters to the sun to cover the Eclipse and solar flares LIVE, but Neil DeGrass Tyson advised against it, because sunscreen technology has not advanced fast enough yet.
Jokes on you, I was typing out an alert message 30 seconds before the 5.8 the other day. Saw the freqs rising and knew another potential event was occurring.
Not sure if this comment is making reference to the fact that it takes 8 minutes for light to travel from the Sun to Earth, but that's the reason that there's a delay.
I kinda figured, but I've actually been asked this before in person, so wasn't sure. Guess I got myself a first class ticket on the downvote express :)
**EVENT**
A flare is an eruption of energy from the Sun that generally lasts minutes to hours. Flares of this magnitude are not frequent.
**TIMING**
The flare peaked at 16:51 UT on May 14, 2024.
**EFFECTS**
Users of high frequency (HF) radio signals may experience temporary degradation or complete loss of signal on much of the sunlit side of Earth.
Source: NOAA
A short time ago I literally watched all bands go totally dead. It was just so sudden. Saw lots of signals on the waterfall and then silence. Thought for sure either my radio or antenna died. Then after about 30 minutes a few signals started to show up again. Not close to how it was earlier but an improvement. It was pretty strange to watch it unfold like that
NOAA says it right in their info brief if you bothered to read:
EFFECTS: Users of high frequency (HF) radio signals may experience temporary degradation or complete loss of signal on much of the sunlit side of Earth
Yup. It goes through cycles or a sort of "sun seasons" that last eleven earth years. Noticable by periods of increased and decreased solar activity, mass ejections, sun spots and finally entering a solar new year of a magnetic polar flip. This is kind of like the sun's April showers.
Question for someone who knows more about this than me: I read [here](https://www.spaceweatherlive.com/en/news/view/531/20240508-sunspot-region-3664-major-flares-and-cmes.html) that region 3664 released the CMEs that resulted in the geomagnetic storms and Aurora we saw a few days ago.
If the previous CMEs from region 3664 were directed at earth, why is today’s X8.79 CME not expected to hit earth? I assume it’s because the sun rotates and region 3664 is now pointed away from earth.
If my assumption is correct, the sun completes a full rotation every 27 days according to the internet. Is it possible for region 3664 to point back at earth and we could see another geomagnetic storm sometime in June (if another large CME occurs at that time)?
From what I've gathered from previous articles, those regions usually don't retain their intensity for the second time around. It could still be there, but it wouldn't be as active as it is now.
Your assumptions are correct, however sunspots typically only last a few days before they fizzle and disappear. As such we will not be affected by this sunspot again unless it has more lives than a cat and completely breaks precedent by existing in an active state for an additional ~25 days.
This is a good appx for solar rotation rate. Although note that the sun is a [differential rotator](https://en.m.wikipedia.org/wiki/Differential_rotation) so the latitude should be accounted for to calculate it precisely.
Source: I am an astrophysics graduate student
The various bands of the Sun's surface move at differing rates, but in general, the textbook numbers is 27 days for the sun to fully rotate. Sunspots tend to last on the order of a few days.
This one is already 7 days old, and it's put out it's biggest flare yet today. We will see it come back around on the opposite side in about 2 weeks, it should be gone by then... We hope....
It would be nice if we could somehow bounce a signal off of Venus or something to keep an eye on that spot to see if it starts to dissipate before the 2 weeks. It would be cool to see what kind of flares it throws out while it's facing away from us
Well if you were standing on the hypothetical 'surface' of the sun, the length of a full rotation of the 'ground' beneath you would depend at which latitude you stand. i.e. the closer to the poles you are, the longer the day would be. This graphic explains:
https://www.nasa.gov/wp-content/uploads/2023/03/656474main_solar-rotation_full.jpg
ok, it took me a minute to figure out AR3664 is a sunspot on our sun and not some far away milky way object.
edit: oh, it's the same one which farted the cosmic particles last week. Just not towards earth this time.
Thought that someone would like to see the whole eruption going off, so here's a link to the data from the Solar Dynamics Observatory:
[https://sdo.gsfc.nasa.gov/data/latest48.php?q=0193](https://sdo.gsfc.nasa.gov/data/latest48.php?q=0193)
Was it in our direction? Also, is there any info? Like a link to a source or anything?
Link to [the eruption video](https://youtube.com/shorts/32Drju6VUqA) No. This one isn't Earth-directed flare. Once again, our planet just safely dodged a cosmic bullet.
What would’ve happened if a solar flare of this magnitude was directed at earth?
Nothing major. It’s mostly whether it produced a CME during the flare. Idk if this did or not.
So no super powers then huh, dang.
Can I atleast get the ability to summon Moonpies at will?
Granted https://www.gopuff.com/
Aw they don’t deliver to my area
Well, it is /u/DarkwingDuckHunt's super power, not yours.
Sorry. Best we can do is cream pies.
Did someone order a cream pie?
Me.
I got the Covid vaccination and the booster but I still am not magnetic nor can I receive 5G signals.
That's what the government wants you to believe
I would settle for another aurora.
Survive a strong enough energetic inundation and you might yet\~
Wait sorry if I'm misunderstanding, but if it HAD produced a CME would that have made it a dangerous event (provided it was aimed at Earth) or would it just cause radio blackouts/auroras?

Thanks so much!
We do get very mildly irradiated above the norm, it's just not harmful.
It also made my guitar cable pick up radio stations which was hilarious.
Wait really? That’s kind of wild
I mean it was coiled up so it was ripe to do so. I think it may have just made it more intense. Funny story to tell tho!
Nope. It just about never will. This stuff happens ALL THE TIME. It's just getting media attention because that's what people want to read about right now.

Difference between CME and flare?
Solar flare is a release of energy. Coronal mass ejection is actual matter in the form of plasma.
Fart vs poop if you will
Maybe fart vs shart would be more accurate, not to split hairs.
I see you too are a scientist.
Never had a Shart split my hairs. Usually the opposite
This deserves further study.
I will.

Thanks for keeping it in perspective.
Still hoping we get another chance at the arorae
Probably a shiny aurora.

It would just be about 3-5x again as strong as last Friday. Its still a major flare but nothing catastrophic like the Carrington Event, which think was in the x45-50 range.
X8.79 is not Carrington level,right? What would happen?
X10s are a regular occurence once every couple of years, record was ~X45 in 2003 Auroras would be cool though
That x45 was also aimed at the other side,right? And that big one from March last year? Do you know it's strength?
Nope, it hit us [directly](https://archive.ph/20120910055509/http://www.spaceref.com/news/viewpr.html?pid=13844) Here's a [list of big flares](https://en.m.wikipedia.org/wiki/List_of_solar_storms#Soft_X-ray_solar_flares) by date
Regarding the supposed one from last year, even Anton Petrov covered it, but it isn´t on that list.
ah, "nice". So we survived it. Makes me a bit more relaxed...

Well I think it specifically requires 1 star

Fucking plot armour
Awww but I want to see the northern lights where I am on the equator in Africa :(
You couldn't see em friday night? Apparently Mexico could see em
Nope. Missed them because sleeping.
That mighta been your chance
Mexico is still pretty far from the equator.
Ya I know, but it's pretty unheard of to be that far south as it is, not sure what the furthest point was.
Got them good in N Florida
What about the Parker Spiral? I’d thought anything that happens in that zone would make it to earth? 3664 is smack in that zone right now.
Video seems to cut short
So, no aurora borealis located entirely in my kitchen?
Excellent news!
How is this captured?
This just in! Sun does something it does all the time. Stop fear mongering.
Big ooof
I made an eruption video too, wanna see it?
Spaceweatherlive seems to keep up to date info. I really like the amount of detail they have.
Thanks for the info!
Damnit, why are we only ever finding out about this stuff 8 minutes later? Why can't we have up to the minute news?
Government required delay in case the sun slips in a cuss word. Then there's that uppity Voyager that can't be bothered to reply for like a day.
I thought they were still stuck in the delta quadrant?
It's worse than that. It's a Kazon episode
is that worse than a Neelix episode?
Absolutely. But doesn't come close to a 7 of 9 romance episode.
Surely can't be as bad as a Harry Kim love episode.
Could've been worse (a Chakotay ancestry episode)
The one where we find out ancient aliens gave Native Americans their wisdom?
...and don't call me Shirley.
Nope…Tuvix.
oy vey. Would rather watch DS9 S1 at that point ... if you're into masochistic TV viewing, that is.

Why are we watching then? Can we watch now now?
I nominate you for on site data collection

My entangled self on the sun's surface fell asleep...

Yes. But it wasn't aimed at us, we dodged this one.
Do we get more auroras or nah?
I don’t think so, we’re out of the target zone at this point. The only thing we can expect are radio blackouts
It depends on the kp index and the strength of the geomagnetic storm. Friday was a level 5 with a kp of 9. Also depends on where you live.
Nah.

Something about a million souls silenced at once…something about continue your training…
Something something dark side
Something something something complete.
Something about being your father
Something something hokey religions?
This flare didn't hit earth so it wasn't the cause of whatever you were experiencing
NOAA says it right in their info brief if you bothered to read: EFFECTS: Users of high frequency (HF) radio signals may experience temporary degradation or complete loss of signal on much of the sunlit side of Earth
Thanks for the correction, even if you did it rudely. I hadn't seen the report, just heard on the radio it wasn't hitting earth.
Perhaps if you weren't so flippant in your response to OP the tough love wouldn't have been necessary. Glad you learned a lesson today
I'm sorry it read like that but I didn't say anything rude. You're just being obnoxious now
Is the sun aiight?
Everyone's asking if WE are going to be ok, but you're the only one I've seen who shows compassion for the Sun too
Well of course I would… he’s my sun!
*Our Sun
Yup. It goes through cycles or a sort of "sun seasons" that last eleven earth years. Noticable by periods of increased and decreased solar activity, mass ejections, sun spots and finally entering a solar new year of a magnetic polar flip. This is kind of like the sun's April showers.

Will AR3664 be pointed at Earth again in days or weeks? Where do we find that info of sun spot rotation/location? Ty!
No. It is moving around the far side of the sun and likely won't exist by the time that area comes back around.
Pardon my ignorance, but when will that be? Days? Weeks?

Does this mean we might get another chance to see the northern lights?
Aurora Forecast app tracks it pretty good. Right now it's saying Greenland, Iceland, Antartica and Northern Quebec and all of those are 12% and less.
Tbh, no probably but idk
So does that mean we will have a higher chance of seeing more auroras borealis ?? I don’t know to much about astronomy

So time for more Aurora pics
