Yup, pretty much exactly that. But again, everything blends together a bit. The reason why that graph you just posted is permanently stuck at "flare class C" or higher at this point in the cycle, and the D-RAP map permanently has some color on the dayside of the Earth, is because right now the baseline level of solar output is high enough that there's always some X-rays warming up the D layer. In 2019, when the SFI was down around 70, that X-ray flux graph would mostly be down at the "A" level (a little over 1% of the current level) and the D-RAP map was all black with a tiny bit of purple. 15 meters was hopeless, but we had daytime 80. Which is a long way of saying it's not just flares. High solar activity gets you more X-rays, and X-rays are good and bad at the same time. But yeah, the shorter X-rays do a lot more harm than good, and flares have lots of those.
No. The sun is a mystery. I mean that in the most scientific way. No one can say yet why some days (or some entire cycles) it has more sunspots but less of the stuff that makes radio good, and sometimes it's the other way around. We know that it's true, but we don't know enough about what goes on inside the sun to say why.
Thanks again, good stuff. I do appreciate you taking the time! I guess I'm going to have to get used to just looking at the Ionograms! Play it be ear every day... Just now managed to catch 3D2BJ on Fiji on 15M CW. With 40W & Wire. So... there IS propagation! And he's in sunlight under the 'blue dome' right now!
WOW WOW WOW LOL LOL LOL LOL I worked a mobile in Madagascar with 100mw and my shoestring from my tennis shoe on 10m He was holding a handheld using 1 watt sitting in a palm tree. Not too bad signals were 20/9
On the NOAA Space Weather site one can view the "Lasco C3" animation. I always see streaks going every which way, this is the longest one I've seen yet. Are these meteorites? satellites? Or aliens?
Protons. Here's a video showing what can happen after a really large proton flare. https://svs.gsfc.nasa.gov/2961
They can go any which way I guess, because that's what I see. There's some there ALWAYS. I like to watch the planets transit, and I'm waiting for a comet to show up!
You are most correct. Phys. Rev. Lett. 131, 051201 (2023) - Discovery of Gamma Rays from the Quiescent Sun with HAWC (aps.org) even more of the 'we didn't know that'... HAWC Observatory Detects High-Energy Gamma Rays from the Sun | Sci.News Longer story with background. The gamma energy 'goes away' in the upper atmosphere. The (just newly recognized) increased radiation has to be doing something - that something' has yet to be fully defined. Please note I posted the original paper up front.
There is still some summer weather to enjoy with all the free time away from the radio. Enjoying The Great Outdoors N3WVB
Have To Say I Love How My Photos Are Deleted From QRZ I Guess They Are Deemed Not Relevant Trying To Put Some Cheer Into A Poor At Best Cycle
Where? You mean this, from your previous post? That's not a deletion, something is wrong with the upload. Looks to me like google isn't allowing a hotlink to the pic.
