Update: G3 geomagnetic storm watch remains in effect for Oct 11 as CME effects continue to diminish.
Update from NOAA Space Weather Prediction Center at 2:11pm EST: A G3 (Strong) geomagnetic storm watch remains in effect for 11 Oct as CME effects continue to diminish. A G1 (Minor) geomagnetic storm watch is in place for 12 Oct due to lingering CME influences in addition to the possibility of relatively weak coronal hole high speed stream effects.

Anyone else obsessively checking SWPC NOAA’s website for tonight’s predictions?
Storm level predictions for tonight dropped from G4 to G3 to G2 now

Is this just passing close to SOHO? I'm trying to find where to go to see what it is. I've noticed plenty of things passing before, this just seems big/or close?

Question about positive ions
Hi all, I apologize if my understanding is incorrect but I'm trying to understand more about the effects of solar flares. My understanding is that the flares release or create positive ions in the Earth's atmosphere. How long does this effect last? Is this detectable for just a few hours or is this something that lasts days or weeks? Any help on this would be greatly appreciated!

Taken at 726 pm local time most of the sky was blood red

Something funky going on here
Anyone know why there is an apparent "slow-mo" effect during the last CME? The time keeps ticking but the CME and comet slow down...

Very low solar wind events?
- mars magnetosphere expands during very low solar wind:

98pc drop at earth.
What does this mean? Is it normal for the sun's reaction to drop this low?

Sun just popped the biggest flare of Cycle 25. X9.0-class! Waiting for news on a CME. Since the source sunspot is Earth-facing, any CME might have an Earth-directed component. If this doesn't turn out to be a dud, this could be very exciting news for aurora watchers!

NASA and South Korea AeroSpace Administration (KASA) plan a mission to set up a solar wind observation station at the L4 Lagrange point to boost understanding of space radiation.

Can someone explain what auroral phenomenon I captured in a timelapse? More info below

Why is the global D-layer absorption layer lower then usual the image below was taken during an M 5.1 flare and usually it’s red but now it’s only green

Space Weather Historical Data
Hi all! I’m a civil engineer who was using a geophysical device recently in Northern Alaska. We were noticing weird patterns with the very low frequency stations we were accessing as their power levels on our device greatly fluctuated over the week we were there. I’m looking for a website that would have the past space weather summary (e.g. Kp index). Hoping this may give some explanation as I’m aware there was a G2 storm while we were there but just want to see if it aligns with the odd power levels.
I found SpaceWeatherLive.com but it doesn’t seem like they have anything for August yet and I am unaware of the reliability of their site. Would appreciate any recommendations for other sources you all may use.

Would a Bot help?
I asked this in another sub, but it was suggested that this might be a better forum.
Would anyone be interested in helping to develop a bot to aggregate the most impactful space weather metrics and post them here periodically (a la the “daily moves” bot on r/wallstreetbets)?
It seems like an active monitor, or daily weather report, of current conditions, might help foster more regular conversation.
I've never built a Reddit bot, but I have a GPT sub and some spare time…

Flying while pregnant - how to tell solar radiation level?
First time poster, so sorry if this is off-topic. But I'm pregnant and scheduled to fly internationally for work at the end of August (21 hours flight time one-way). The standard medical advice says flying during pregnancy is generally safe, except for when there are rare "solar flares." How would you check if there are going to be solar flares (would you just check this website: www.swpc.noaa.gov?), and how far in advance would one know if there's going to be high solar radiation? Thanks for your assistance.

Why is my goes x-ray flux not updating when there is a big flare it won’t update

Solar storms and electronics
I was simply watching random videos about random stuff when I saw a video about "the internet apocalypse" and "a solar storm can destroy your phone". I made the mistake of clicking on it and now I'm freaking out. What are the ACTUAL chances of a solar storm destroying electronics (permanently)? Sorry for the dumb question.

Solar activity 7/27/2024
“MORE CMEs ARE COMING: Today has been a busy day on the sun. Sunspots AR3762 and AR3766 produced a series of M-class solar flares, shown here in an interest-compressed movie from NASA's Solar Dynamics Observatory:
Radiation from these flares ionized the top of Earth's atmosphere, causing a rolling series of shortwave radio blackouts around all longitudes of our planet. Ham radio operators may have noticed loss of signal below 30 MHz particularly around 0230 UT, 0545 UT and 1040 UT.
Debris from these explosions may strike Earth in a few days. Coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) recorded a mash-up of at least two halo CMEs emerging from the sun .
Because of recent activity on the farside of the sun, we cannot rule out the possibility that one of the clouds pictured above is a backside event heading away from Earth. However, confidence is high that the first and brightest CME in the movie is associated with an M4 flare from AR3766 and has an Earth-directed component. A NASA model suggests it will strike Earth during the early hours of July 30th. The impact could cause a G1 to G2-class geomagnetic storm.
Stay tuned for updates as the forecast is refined by further modeling. “

Request : How to learn more about Space Weather
I have no university education and want to learn more about space weather. I have always enjoyed space but I always lacked being around any teacher or educator who could teach it to make it understandable or relatable. This past year I read the book called 'The Spinning Magnet' by Alanna Mitchell and finally got a more deeper understanding about the Earths magnetism, how it works, how the field is weakening, how it can 'reverse', and how it protects us from space weather. I am looking for more books, or literature or YouTube videos or whatever that can describe more about these concepts without me having to have a PhD or masters degree to understand. Im quite average but I like to learn! Please feel free to share with me anything about Spaceweather, geomagnetic storms, more about pole 'reversals', and more.
