Vancanneyt Sander Posted August 28, 2021 Share Posted August 28, 2021 Region 2860 has developed quite nicely in the past 24 hours and produced its first M-class solar flare! M4,7 with an earthward directed CME. We await LASCO imagery for more details. it’s worth noting the region has a strong delta spot in the center squished to a spot of opposite polarity. More strong solar flares are likely. Exciting times ahead! 1 Link to comment Share on other sites More sharing options...
Marcel de Bont Posted August 28, 2021 Share Posted August 28, 2021 Very nice to finally have some solar action again but the resulting CME looks very disappointing coming from such a nice flare... 1 Link to comment Share on other sites More sharing options...

Im amazed at how fast you are feeding us with info, given its only midday in Europe and the flare just happened. Love you for that! So, as Im a noob at reading Lasco properly since this is my first Cycle observing properly, how do you determine that it is dissapointing? Is it faint/diffuse? Not fast? Not a direct hit? 1 Link to comment Share on other sites More sharing options...
Marcel de Bont Posted August 28, 2021 Share Posted August 28, 2021 Thanks! We are based in Europe as well so looking at LASCO and STEREO fits right into the ''before lunch'' time slot. I just look at STEREO COR2 and SOHO/LASCO imagery in motion. After looking at CMEs for years you quickly see which ones are interesting (fast/dense/well aimed at Earth) and which aren't. Here is another image from LASCO, it really does not look good. It is just really faint and slow. Here you have an example from July 2000 of how I want a CME to look like https://www.spaceweatherlive.com/images/Archief/2000/Flares/200007141024X5.7.mp4 Link to comment Share on other sites More sharing options...
Newbie Posted August 28, 2021 Share Posted August 28, 2021 (edited) Yeah great looking sunspot. Hope it continues to develop. 😃 And it's beta-gamma-delta now. Now its back to beta -gamma 😃 😃 Edited August 28, 2021 by Newbie Link to comment Share on other sites More sharing options...
Marcel de Bont Posted August 28, 2021 Share Posted August 28, 2021 It is definitely Beta-Gamma-Delta. I edited it manually but it seems the website removed my edited when it fetched new data from NOAA haha. Link to comment Share on other sites More sharing options...

Jesterface23 Posted August 28, 2021 Share Posted August 28, 2021 Watching and waiting. Watching and waiting. I'd guess it's a good sign at least when the X-Ray flux can hold in the C-Class range for a while. lol Link to comment Share on other sites More sharing options...
MinYoongi Posted August 29, 2021 Share Posted August 29, 2021 It first looked like its slightly starting to decay but now it regained strength. Angry Sunspot 😂 Link to comment Share on other sites More sharing options...
Drax Spacex Posted August 29, 2021 Share Posted August 29, 2021 Indeed. The region is still quite fussy. The magnetogram of 2860 looks like a Jackson Pollock painting - a splattered mess. The latest, an impulsive C8.13 "Captain Hook" flare at 2021-08-29 10:03. The wide black band along the equator (AIA 211) - is that a coronal opening producing a solar wind? Could that cause any ejecta (my new favorite word) to be blown north or south of the solar equatorial plane, deflecting it away from Earth? 1 Link to comment Share on other sites More sharing options...

Yeah, and 14 flares in 48 hours.. very cool little (gigantic) paint splotches indeed. Link to comment Share on other sites More sharing options...
Popular Post Drax Spacex Posted September 3, 2021 Popular Post Share Posted September 3, 2021 (edited) So long AR2860, and thanks for all the flares! Final count: 42 B, 28 C, 1 M Some interesting facts about the 2021-08-28 AR2860 M4.8 flare: 1) At the time of the flare, it was lined up almost directly with Earth in longitude (location=S29W01) 2) AR2860's longitude in Carrington coordinates (Sun-fixed) was 1° (+/-1) for the duration of its travel across the solar disk. At the time of the M-flare, the Earth-relative Stonyhurst longitude was coincidentally also 1°. 3) The M-flare occurred 56 days after the X1.59 flare of 2021-07-03. The synodic period that defines the number of days in a Carrington rotation is 27.2753 days. This M-flare happened approximately two synodic periods after the X-flare. 4) The two most recent strongest flares occurred on the last day and next-to-last day of their respective Carrington rotations. This M4.8 flare occurred on the last day of Carrington rotation 2247. The X1.59 flare occurred on the next-to-last day of Carrington rotation 2245. Edited September 5, 2021 by Drax Spacex X1.59 next-to-last day of 2245 5 1 Link to comment Share on other sites More sharing options...
