Flareguy18 Posted July 21, 2022 Share Posted July 21, 2022 Just after 21/0100 UTC, SWPC/NOAA issued a Type II and Type IV radio alert for an eruption centered around AR3060. It had a C-class flare and associated CME. I first saw it in GOES-16 SUVI, now it is visible in LASCO C3. It is a very faint CME, actually is hard to see it because it happens just after a much brighter, far-side CME which is still on the frame as the full-halo occurs. It looked fairly symmetrical in SUVI, but it's very hard to see in LASCO. It might be slightly more dense to the north. SWPC predicts a July 23rd arrival, which could be interesting since we should still be under the influence of the CH HSS. I'd love to look at it through CACTus, but the links seem to not be working for me right now. If anyone has some nice difference images of it, I'd love to see them! 1 1 Link to comment Share on other sites More sharing options...
Sam Warfel Posted July 21, 2022 Share Posted July 21, 2022 I hope it gives a decent storm, even though it’s faint! Full-halo CMEs are far too rare these days 😅 1 Link to comment Share on other sites More sharing options...
Solarflaretracker200 Posted July 21, 2022 Share Posted July 21, 2022 (edited) Wait. So since I haven’t been online as much as I wanted to be on, my question is did a C class solar flare cause a full halo CME?

You are going to basically strain your eyes looking at it though because it's so faint 😂 it was pretty near the sun's equator at center disk.

SunspotRager93 Posted July 21, 2022 Share Posted July 21, 2022 Aren’t the full hale CME’s extremely rare? 1 Link to comment Share on other sites More sharing options...

No I don’t think so. 3 hours ago, Orneno said: I hope it gives a decent storm, even though it’s faint!

Sam Warfel Posted July 21, 2022 Share Posted July 21, 2022 Thanks to @Vancanneyt Sanderfor the updated links, here's the CACtus and Dimming Detector pages for the flare/CME from this region! They show it really well https://www.sidc.be/solardemon/dimmings.php?science=0&did=3983 https://www.sidc.be/cactus/out/CME0024/CME.html 1 Link to comment Share on other sites More sharing options...
Jesterface23 Posted July 21, 2022 Share Posted July 21, 2022 I have a preliminary arrival time of 2022/07/23 08:10Z -4/+12 Hours. I didn't even notice this CME until the G2 watch was sent out lol. A bit busy, I literally have 450k+ coronagraph images and counting right now and Windows 11 wants to give up. 1 Link to comment Share on other sites More sharing options...

However, they are the least common because it essentially has to be a CME coming straight from the central disk region. If it's off center even just a bit, it will end up being a partial-halo or less. It all comes down to if the CME is headed squarely at Earth or not. 1 Link to comment Share on other sites More sharing options...
