I've seen limb events produce pretty significant radiation storms in the past. 1 Link to comment Share on other sites More sharing options...

I Think any radiaton storm wouldve made itself noticeable by now? Link to comment Share on other sites More sharing options...

Solar radiation storms can sometimes take hours to manifest. We will have to watch the proton flux data for a while to be sure. Link to comment Share on other sites More sharing options...

KW2P Posted April 20, 2022 Share Posted April 20, 2022 29 minutes ago, MinYoongi said: Whats SFI As was answered by LunarLights58, it's the 10.7 cm or 2800 MHz radio signal emitted by the sun. It appears to emanate from the chromosphere. It was found long ago that the strength of the 10.7 cm radio signal from the sun correlated pretty well with sunspots and overall radiation. This was handy because the radio signal was measurable from the ground before we had space-based measurements and we have long-term precise measurements going back to 1947. SFI is the single-number value that, for radioheads like me, expresses how much "help" the sun is giving us for radio propagation. At the bottom of the cycle, the number hovers around 72 and we're all depressed. Anything above 100 is an improvement. 130 is good. 160 and above is what we want to see at the top of a solar cycle. A cycle that tops 200 is what everyone dreams of because the upper shortwave bands open up for worldwide communication 24/7 and is super exciting for radio people.

FredSchuller Posted April 20, 2022 Share Posted April 20, 2022 It's no replacement for STEREO-B, but Solar Orbiter is currently 153 deg west of the Earth-Sun line, thus well located to observe this region. Looking forward to see the images when they become available... In particular, the STIX instrument will provide high resolution X-ray data.

Sammyy Posted April 20, 2022 Share Posted April 20, 2022 (edited) I was lookin through the archive the other day. And noticed that sometimes x-flares come very close together. Like 3 days in a row. Especially somwhat early in a solar cycle. It seems a little similar to whats happening now. With the exception of the majority of the flares being m-flares Edited April 20, 2022 by Sammyy 1 Link to comment Share on other sites More sharing options...

With the exception of the majority of the flares being m-flares that's normal when there are magnetically complex regions that are capable of producing strong solar flares. . Although 'early' in the cycle, it's still behind SC24 and SC23 in terms of X and M-class flares but we still have 8 months to go. See our solar cycle tracking page where we have a graph with the number of C, M and X-class events per year. 1 Link to comment Share on other sites More sharing options...

Hello all This I am wondering, too. Both, Spaceweather and Spaceweatherlive are at 135 the last days. Jan Alvestad has the 160 since early morning ready. So why this delay in updating on both common sites? Regards, Chris Link to comment Share on other sites More sharing options...

See our solar cycle tracking page where we have a graph with the number of C, M and X-class events per year. I guess we'll have to wait and see. From what I understand cycle 23 lasted at least 1 year longer than expected. Maybe that had an affect on solar cycle 24. Anyhow, if you look at the amount of C, M & X flares so far this year. And expect the same amount of them over the whole year it would be slightly higher than solar cycle 24. Link to comment Share on other sites More sharing options...

Sammyy Posted April 20, 2022 Share Posted April 20, 2022 1 hour ago, MinYoongi said: Exactly. Well so far in the cycle they haven't achieved that pattern of x-flares continuously over 2-3 days. Which is why I mentioned it. Since it seems likely to occur now or almost close to. As far as I understand the latest x-flare wasn't from the area which one would expect another x-flare from either Link to comment Share on other sites More sharing options...

I like them a lot because they raise UV and X radiation flux WITHOUT throwing a CME at us. This is ideal. High radiation = good. CME = bad. From the standpoint of me and millions of radioheads. Since none of us are controlling this, if a big CME happens, so be it. I'll watch the aurora along with everyone else. But I'd rather be easily communicating by radio with someone halfway around the planet using just 15 watts of power rather than 1500 watts to produce faint signals that are hard to copy amidst the noise. There are many forms of radio that don't depend on ionospheric propagation (VHF, microwaves, moonbounce, satellite operation) but my favorite field of radio is HF (shortwave), which is all about the ionosphere. What we all have in common here is an intense interest in the sun, just for different reasons. 🙂 2 Link to comment Share on other sites More sharing options...
