Landon Moeller Posted September 24, 2022 Share Posted September 24, 2022 3110 seems to be quite the crackling little sunspot group! Just shot off another fast CME around 1700 UTC if you look at Angstroms 195. 2 Link to comment Share on other sites More sharing options...
Sam Warfel Posted September 24, 2022 Share Posted September 24, 2022 It seems quite active, although I’m a bit confused why, as it doesn’t seem to be that complex? Or am I wrong about that? Either way, an active AR on the east side is promising! Keep it up 3110! 1 Link to comment Share on other sites More sharing options...

Newbie Posted September 25, 2022 Share Posted September 25, 2022 (edited) Solen called this BGD on 25/9 @ 10:25UT. The image below is taken @ 12:30UT. Latest flares were C5.6 and C1.1. The case for gamma is stronger than it is for delta... but it's all very weak. Agreed SFT it's boring! N. 9 minutes ago, Solarflaretracker200 said: Ok this region needs to do something.

WildWill Posted September 25, 2022 Share Posted September 25, 2022 This one, along with AR13102 and 3107 have kicked out a few pretty nice looking CMEs. LASCO 48 hour loop is worth taking a look at! WnA 1 Link to comment Share on other sites More sharing options...

Is the region worth watching? Solar flares affect all layers of the solar atmosphere (photosphere, chromosphere, and corona). The plasma medium is heated to tens of millions of kelvins, while electrons, protons, and heavier ions are accelerated to near the speed of light. Flares produce electromagnetic radiation across the electromagnetic spectrum at all wavelengths, from radio waves to gamma rays. Most of the energy is spread over frequencies outside the visual range; the majority of the flares are not visible to the naked eye and must be observed with special instruments. Flares occur in active regions often around sunspots, where intense magnetic fields penetrate the photosphere to link the corona to the solar interior. Flares are powered by the sudden (timescales of minutes to tens of minutes) release of magnetic energy stored in the corona. The same energy releases may produce coronal mass ejections (CMEs), although the relationship between CMEs and flares is still not well understood. Associated with solar flares are flare sprays. They involve faster ejections of material than eruptive prominences, and reach velocities of 20 to 2000 kilometers per second. Wiki. With solar cycle No. 20 new insight into the flare-spray phenomenon was attained due to several innovations in solar optical-observing techniques. From combined analysis of 13 well-observed sprays which occurred between 1969–1974 itcwas concluded that (i) the spray material originates from a pre-existing active region filament which undergoes increased absorption some tens of minutes prior to the abrupt chromospheric brightening at the ‘flare-start’, and (ii) the spray material is confined within a steadily expanding, loop-shaped (presumably magnetically controlled) envelope with part of the material draining back down along one or both legs of the loop. (Tandberg-Hanssen, E.; Martin, Sara F.; Hansen, Richard T. (March 1980). "Dynamics of flare sprays". Solar Physics. 65 (2): 357–368. Bibcode:1980SoPh...65..357T. doi:10.1007/BF00152799. ISSN 0038-0938. S2CID 122385884.) The duration of a solar flare depends heavily on the wavelength of the electromagnetic radiation used in its calculation. This is due to different wavelengths being emitted through different processes and at different heights in the Sun's atmosphere. A common measure of flare duration is the full width at half maximum (FWHM) time of soft X-ray flux within the wavelength bands 0.05 to 0.4 and 0.1 to 0.8 nanometres (0.5 to 4 and 1 to 8 ångströms) measured by the GOES spacecraft in geosynchronous orbit. The FWHM time spans from when a flare's flux first reaches halfway between its maximum flux and the background flux and when it again reaches this value as the flare decays. Using this measure, the duration of a flare ranges from approximately tens of seconds to several hours with a median duration of approximately 6 and 11 minutes in the 0.05 to 0.4 and 0.1 to 0.8 nanometre bands, respectively. Solar flares lasting longer than approximately 30 minutes can be regarded as long duration events (LDE). Wiki. The point is, during an eruptive flare, material is being ejected the whole time the flare is active and the velocities of the ejecta vary considerably. That is why when you look at the Cactus model for CME's there are multiple CME signatures all with varying velocities and directions with the recorded velocity being the median for the data set. Often with smaller eruptions the highest velocities are over a small angular width, you might expect this from a flare spray. So it is possible that C flares can produce high speed ejecta especially if a flare spray is triggered. Neither 3107 nor 3110 seem to be doing much. N.

Landon Moeller Posted September 28, 2022 Author Share Posted September 28, 2022 Looks like a filament-type feature just erupted near 3110 and just north of the CH. CME likely a result in the Earth-Strike zone. But will there be enough westward component to the CME? Remains to be seen. I’d say glancing blow possible Link to comment Share on other sites More sharing options...
Landon Moeller Posted September 30, 2022 Author Share Posted September 30, 2022 3110 is getting more magnetically complex, and fast. Just in the last day, its trailer spots have grown and have earned a beta-gamma classification as of this morning. It also appears to be trying to erupt more and more. It may snap at some point and send a CME our way. Link to comment Share on other sites More sharing options...

Landon Moeller Posted October 1, 2022 Author Share Posted October 1, 2022 AR 3113 just shot off a slow CME between 12 and 13 UTC this morning, as you can see via the subsequent dimming. There doesn’t appear to be enough easterly component to be directed at earth, but never say never with the Parker spiral I suppose! Link to comment Share on other sites More sharing options...
