MinYoongi Posted May 25, 2022 Share Posted May 25, 2022 Hello 🙂 ! Did we just get an M Class Flare from an Area of Plage? I'm not seeing any Sunspot on the Intensigram for today. Link to comment Share on other sites More sharing options...
mozy Posted May 25, 2022 Share Posted May 25, 2022 We're getting M-class flares from plage areas but our big region with multiple deltas can't even produce one 😆 Looks eruptive aswell Link to comment Share on other sites More sharing options...

We got a Type IV radio emission, but i dont see type 2. What does that mean? Link to comment Share on other sites More sharing options...
mozy Posted May 25, 2022 Share Posted May 25, 2022 It could be somewhat earth directed indeed Don't really know the difference between them either. For me it's just radio emission = CME 😅 Link to comment Share on other sites More sharing options...

For me it's just radio emission = CME 😅 Is it in a good position for an Earth Directed CME? I'd say its a tad bit west but a glancing blow should be 100% possible at last. I dont see anything in Stereo yet 1 Link to comment Share on other sites More sharing options...

MinYoongi Posted May 25, 2022 Author Share Posted May 25, 2022 update : CME visible in Stereo, so there def. is one! 3 Link to comment Share on other sites More sharing options...
Sam Warfel Posted May 25, 2022 Share Posted May 25, 2022 Very interesting this came from a spotless (and maybe even plage-less) region! It does seem eruptive, can’t wait for LASCO. 1 minute ago, MinYoongi said: update : CME visible in Stereo, so there def. is one!

According to Noaa's Forecast Discussion from 14UTC it decayed from an Alpha spot to plage, so thats why i chose the title 5 minutes ago, mozy said: Most likely a glancing blow at most Keep me updated 🤗 @Orneno 👀 !!

Only thing it can confirm is that a CME is produced. 994 KM/s. This is only the Shockwave in front of the CME so the CME itself will be a little bit slower, but that does sound good, right? @mozy Also new imagery : 1 Link to comment Share on other sites More sharing options...

Jesterface23 Posted May 25, 2022 Share Posted May 25, 2022 With what I can come to with what is available, I'd have a preliminary arrival time of 2022/05/27 18:50Z -6/+18 hours. Link to comment Share on other sites More sharing options...

With 990km/s shock speed i dont think it will be that fast.. (the shock is always faster than the cme) Link to comment Share on other sites More sharing options...

The full halo of the CME is light and hard to see in normal imagery, but it is coming. Link to comment Share on other sites More sharing options...

Hello Min, we actually had a Type II emission from this flare. Below are the main types of radio emissions from the Sun, although there are sub groups within these categories. They differ by their emission mechanisms, in other words how the emission is produced. (Can be be quite involved) Type I: short radio emissions that occur in large numbers associated with a continuous emission and can last hours to days. Type II: strong radio emissions with frequency shift from high to low values which last minutes.They are usually associated with CME's and are produced at the leading edge of the CME where shock waves accelerate the electrons responsible for plasma emission. Type III: strong radio emissions with short duration and frequency shift from high to low values, which last seconds. Type IV: continuous radio emission which can last from hours to days.These emissions arise from fast moving electrons trapped within magnetic fields of an erupting CME. Type V: continuous radio emission which is associated with type III, recorded in frequencies lower than 100 MHz and which last 1-2 minutes. These are quite rare. After the sun has produced a solar flare, and the x-ray flux has taken a long time to return to background flux levels (ie a long duration flare), it's a good chance, there is an associated CME. If Type II, or Type II and Type IV radio bursts (which often follow after Type II) are detected this is a good indication that a CME has been launched. Type II and Type IV radio bursts are usually associated with CME's and that is why they are quickly reported once a solar flare has occurred. Type IV tend to be produced from bigger eruptions. If you need more information wiki Solar radio emission. Newbie Edited May 26, 2022 by Newbie 2 Link to comment Share on other sites More sharing options...
Newbie Posted October 12, 2022 Share Posted October 12, 2022 (edited) I posted the above a little while back it may help explain the question about radio bursts and CME's on the thread AR3112. N. Edited October 12, 2022 by Newbie 1 Link to comment Share on other sites More sharing options...
