Sunspot region 3664 really putting the “active” into active region.. Look at all those halo CMEs popping off! And another released this morning 👀 (Hopefully this actually posts as a video this time)

AR 13668 continues to produce eruptive flares. This X2.2 flare on May 9 was associated with another halo CME, likely Earth-directed. The messy geo-space environment starting May 10 or 11 and lasting a few days will be explained by @AusSpaceAgency, @TamithaSkov and other experts.

The most intense auroral oval forecast I've ever seen from the OVATION model. G5 anyone?

SWx TREC’s Bhagyashree Waghule took 2nd place in the 104th @AMS #SpaceWeather student poster competition. Her poster discussed Earth's #magnetosphere, transient internal structures, magnetic currents, and #GeomagneticStorms. ams.confex.com/ams/104ANNUAL/…

Congratulations to Luis Navarro Dominguez for earning a @NASA ECIP grant advancing space weather research #swx colorado.edu/aerospace/2023…

Congratulations to Yang Wang for earning a @NASA ECIP grant to study how space weather affects Earth #swx colorado.edu/aerospace/2023…

CONGRATULATIONS to @bvwaghule for completing her @CUEngineering Space Weather Certificate! Well done

@spaceweather That is not a solar flare - it's a prominence eruption. The thing that is 588,000 km across is the prominence plasma structure, not the "flare". Flares are the photons that accompany Solar Magnetic Eruptions.

#OTD 19 Dec 1973 pic taken during Skylab 4 shows one of the largest solar flares ever recorded, more than 588,000 km (365,000 mis). across. Larger image flickr.com/photos/nasa2ex… #spaceweather #heliophysics #solarphysics

@capitolweather #angrysun The Sun may have been smiling on October 27th, but yesterday it was upset about something. Could severe #spaceweather be on the way? Or is this a message about #Election2022?

Really nice 3-part CME today around 02:00UT!

Excited to hear Sage Andorka at the National Academies Space Weather Panel say USSF is looking for students trained in space weather and space weather forecasting. Space Weather TREC at CU Boulder was created for that very reason! #SWx #NationalAcademiesSpaceWeatherPanel

Sun, we need to talk about your flare. 🌞 The Sun emitted a significant solar flare on March 30, peaking at 1:35 p.m. ET (17:35 UTC). Our orbiting @NASASun Solar Dynamics Observatory captured the action: go.nasa.gov/3uJMtAS

@halocme Bz rotation is "flux rope like" but rarifaction shock in density and no evidence of shock in speed points more to a CIR. I'm answering "No - no CME in evidence here."

Quiz in heliophysics. In the plot below, is there a CME? If so how many? Draw vertical lines to indicate the boundaries of the features (shock, sheath, ejecta or ICME).

@CUEngineering @CUBoulder @theNAEng Congratulations to our colleagues Brian and Zoya!

NEWS: Two @CUBoulder Engineering professors were recently elected to the National Academy of Engineering (@TheNAEng)! Both Brian Argrow and Zoya Popovic are receiving one of the highest distinctions bestowed upon an engineer. 🏆 Learn more about them: buff.link/7oexs

Space Weather TREC is happy to announce Julie Barnum @julieirene17 as the new Director of our Deep Learning Laboratory - one of nation's premier labs for machine learning research in Heliophysics! Thanks to sponsors @AFOSR and @NASA for making the DLL possible!

@halocme Too bad Mars was also out of the blast zone. Might have been a repeat of the 2013 "Carrington at Mars" event.

Both the Parker Solar Probe and BepiColombo were so located that they were exposed to huge flux of solar energetic particles (SEPs). This SEP event must have been extremely intense, given that it was observed even by GOES at Earth, very poorly connected to the CME.
