The Union of Radio Science (URSI) Asia-Pacific Radio Science Conference is accepting submission for papers to be presented for the conference on August 17 to 22, 2025, in Sydney, Australia. The deadline is tight, papers must be submitted by February 20, 2025.

The topics of interest are listed on the announcement, but in general they pertain to electromagnetic wave and radio propagation, the ionosphere, radio astronomy and similar . Student papers are also accepted.

I have a proposal that I'm looking to get funded. It is using generative models to forecast space weather with a target horizon of 12-24 hours. I strongly believe that we have some innovative ideas.

Unfortunately, no one on my team has a space weather background. We all have PhD's in geophysics. I have over 30 years of experience doing machine learning research (30 years is not a typo). I'm looking to add a consultant to our proposal to strengthen it. Greatly prefer someone with a PhD and a publication history or at least a publication history. Work must be done in the US. Please send me a message if you are interested.

Moderators: I apologize if this post isn't allowed. It seems space weather related.

As you are likely aware, many subs are banning links to X/twitter as a reaction and a protest against Elon Musks' "historic gesture". Oh, hell, call it what it was, a Nazi salute. Musk has not denied the claim, much less apologized. Given this repulsive gesture, the r/spaceweather sub will also enact such a ban, starting today.

This ban is not to be construed as a political statement. Instead it is a simple act to stress that Nazism is unacceptable in a civilized society. The horrors Nazism has inflicted on the world need no explanation and it is repugnant to see their symbols being used in the 21st Century.

The r/spaceweather sub is a low traffic, high quality sub. Hardly any posts in recent memory have had X/twitter links so I expect this policy banning said links from posts will have minimal to no impact on traffic. If an X/twitter post is deemed important to this community, users are urged to share screenshots of such a post, or preferably, links to any external source that may be the embedded in an X/twitter post.

Hi guys, I won a local NASA hackathon last year, with a modern space weather monitoring platform I developed, and I'd love to hear your thoughts and see if I can improve it. It's called GalaxOS.

Thanks!

A study of data collected by the Kepler space telescope on other stars with Sun-like fundamental parameters shows that superflares occur roughly once per century in stars with Sun-like temperature.

I apologize as I am writing this as a near complete layperson.

Sometimes when the KP index is high for my area, I will go out and attempt to see the aurora borealis. Sometimes I'm successful and sometimes I'm not but what I do always see when I go out are these streaming fast moving jets of what appears to be plasma bouncing off electromagnetic waves of some sort. It's always incredibly rapid, incredibly fast moving, and often in an arch shape or a boomerang shape. and I managed to catch it on video a few times, but I don't have a name for it. There are no colors to speak of, and I realize that it can just be a sub classification of the aurora borealis itself, but it seems to not fit with the same pattern of light and relative slowness that the aurora has. but I'm wondering what this thing I'm witnessing is called. Thank you!

Professor Chris Scott tells the history of the Appleton experiment that led to the discovery of the ionosphere, the link between the ionosphere and the solar cycle, and abouut kicking off citizen science project to identify long term trends from archived measurements of ionospheric height. https://www.youtube.com/watch?v=JWop2aGKKSE

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 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.

Storm level predictions for tonight dropped from G4 to G3 to G2 now

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!

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...
