Question about Kp index Seasonal variation

I am current working on a machine learning model to forecast Kp-index. I wanted to include the Month since https://www.sidc.be/PRODEX_SIDEx/docs/Space_Weather_Forecasting_Guide_latest.pdf says geomagnetic activity is correlated to the month of the year. But there are also vague mentions of Kp being compensated for seasonal variations in other sources. Is Kp-index compensated for the kind of seasonal variations in the link above or is that some other seasonal variation ?

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!

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?

  1. mars magnetosphere expands during very low solar wind:

https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023JA031935

  1. https://solarviews.com/eng/sunpr1.htm

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.

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
