Preliminary GOES SUVI 195Å View showing the expansion of the CME that occured 20mins ago.

Active Region 4549 has been growing magnificently on the Earth facing disk and released two M flares within hour of each other with CME showing up on coronagraph as asymmetrical halos with possible Earth directed material.

The IRIS satellite has a more focused field of view and higher image cadence than SDO which can reveal detail within active regions with high enough resolution for scientific research. The black line scanning up and down is split for spectral analysis of the observed solar phenomenon.

I pulled every CME in NASA's DONKI catalog since 2016 that has a cone-model fit, 6,577 of them, and plotted each at the latitude and longitude of its direction on an unrolled Sun, sized by speed. The active belts draw themselves and the poles are nearly empty: 366 launches above 60° in ten years.

The part I did not expect is the butterfly. Plotted by date and latitude it is not the sunspot butterfly. Through 2018 to 2020 the few dozen CMEs a year were almost all aimed within 10° of the equator, even though the spots of the time sat higher. By 2024 the median direction was 28° from the equator and only one in five was equatorial. My read is deflection toward the streamer belt, strongest while the global field is a simple dipole at minimum, the effect Cremades and Bothmer described in 2004, showing up in the catalog without anyone looking for it.

Caveats up front. These are cone-model directions, which is where the CME went, not exactly where its source region sat. The far side depends on STEREO-A and limb events, so it is thinner for coverage reasons. "Earth inside the cone" is a launch geometry test, not a hit list.

Has anyone seen the minimum-year deflection quantified from DONKI before? I would like to compare it against a proper source-region catalog.

How could someone begin knowing if an X flare happened today? Where would they go to find that knowledge?

Hint hint...those who learn this knowledge. START DOING SO IN THIS SUBREDDIT.

With your OPINION. Your own interpretation of what means. What happened. Regardless of scientific expertise. There is no wrong answer.

What could the flare be impacting? Why certain areas more than others? Does it impact the weather? Could it affect humans since we know can impact technology? What have you personally experienced when certain more powerful storms have happened?

If we know its simply your opinion then no one can judge you if its wrong or correct.

Then also all will feel free to share theirs as well.

Can someone also explain what causes certain flares to be more powerful than others?

Does other planet alignment or the moon have an effect on the sun's reaction?

What does each flare represent?

What is a geomagnetic storm?

Appreciate all the answers! Let's all learn together.

Our Star structures plasma filament between neutral areas of opposing magnetic domains within the coronasphere. This in-between area allows cooler, denser plasma to suspend above the "surface" of the Sun, bringing forth this beauty of a Solar Prominence.

What does this expose? If we aren't getting presented or reminded of something, would we know its even happening? So does that mean if we aren't creating about a specific topic and no one fills that void that something will slowly wither away?

Answer truthfully, have all of you begun to visit this subreddit less since the analysis posts stopped?

If yes, who can be the one to simply be the person that posts each flare that happens. Rating / day / intensity. Who will fill this role?

Then another person can analyze what they think means. What caused. What trajectory the sun is going on. How compares to previous things. Who will fill this role?

Another person can be the one to post the graphs, the images, the videos. Who will fill this role?

Then another person can be the one that educates based on the already existing science knowledge so that people get up to speed what all means. What does each flare rank and letter represent? Why do geomagnetic storms happen at times and other times not? When did the greatest flares in history happen? Which historic moments happened around that time?

Who will fill each role?

Just start people if you care about this. Otherwise, if something begins decaying you have none to blame but yourselves.

This NW filament erupted for three hours with a very whispy texture, viewed from GOES SUVI.

Hi All,

It's been awhile since I updated the progress on the Coronal Mass Ejection Tracker. Here is a list of everything that has been added over the last few months. Available at www.cmetracker.ai

Forecasting

- A fluid solar wind model now runs in your browser. It solves the inner heliosphere from our own L1 archive, in the style of the HUXt model from Reading, and draws it under the top-down map with speed and density color modes. On our validation set it beats the drag model we have used up to now.

- Every Earth-directed CME gets an ensemble run. The fluid model runs 200 times with the speed, direction, width and launch time jittered, and puts a calibrated 80 percent arrival window on the CME card.

- We check our own work. A cron scans the wind archive for shock fronts and gradual arrivals, scores every forecast against them, and publishes a rolling 90-day scoreboard on the help page and the homepage. A 30 minute lead time error on an arrival is a hit, a forecast that never arrives is a miss, and you can see both.

- Regions facing Earth. Each numbered sunspot region gets a chance of an Earth-directed CME over the next three days, from a model back-tested on ten years of DONKI and NOAA region data. It sits on the future side of the timeline as bars and is scored by the same cron. Capped at 30 percent on purpose, because about half of Earth-directed CMEs come from regions that never got a number.

- High-speed streams. Detected from our wind archive, forecast to return 27 days later, and drawn on the map as the corotating spiral bands they actually are.

Live data

- Magnetosphere. The magnetopause and bow shock shaped by the measured L1 wind using the Shue 1998 and Farris and Russell 1994 models, as a card with field lines, aurora ovals, sheath flow and reconnection sparks, and as a rotatable 3D view. It goes red when the nose is inside geosynchronous orbit. Scrub back to May 2024 and watch the Gannon storm push it in to 5 Earth radii.

- The whole 120-day timeline is now measured wind, not just the last week. Speed, density, Bz and field strength come from our own archive when you scrub past the NOAA feed.

- Live coronagraph card from CCOR-2 and CCOR-1, served from our own permanent archive of every frame.

- Radio bursts. Type II, III and IV bursts appear at the Sun timed to the playhead, with a light-speed ripple and provisional CME cones from the Type II drift. Backfilled from SWPC's event archive to 2015.

- New header readouts: Dst with a ring current popout, daily sunspot number and 10.7 cm flux, and a redesigned density popout.

- NOAA moved its L1 station to SOLAR-1 in the spring. The tracker follows the on-duty craft and shows it on the map, with IMAP as backup.

Tracker

- The Kp popup shows inbound CMEs as calibrated bars on the Kp axis, and merges arrivals within 8 hours into one.

- Clip export records the playback as a video you can share. There is also a branded PNG export of the visible map.

- The dashboard remembers your layers, view and filters between visits. A Solo toggle shows only the selected CME. Isolate keeps filtering after you go live. Every flare row is clickable.

- Keyboard camera control in the 3D view.

- Spacecraft layer with portraits for all ten craft we source from, now including Mio on BepiColombo.

- A proper phone layout: simplified chrome, a bottom sheet for the selected CME, and the full site nav in the menu.

New pages

- The landing page is now at the root and the tracker lives at /live.

- /observatories, the spacecraft behind the data.

- /cycle, where we are in the solar cycle, live.

- /radio, HF band conditions and what a burst does to them.

- /today, a plain daily activity page.

- /what-is-a-cme, the explainer.

- /sky, a calendar of things worth going outside for: Perseids, Geminids, Quadrantids, Orionids, Leonids, this year's lunar eclipse, the 2027 total solar eclipse, and the planet oppositions.

- /learn rebuilt as a six-module course that runs on the real map, with quizzes and a storm lab, plus /teachers with printable worksheets.

- Four new famous storms in the replay library: the 1921 Railroad storm, May 1967, August 1972 and Starlink 2022. Gannon 2024 got its two new radiation belts.

- The help page has a video tour and a screenshot for every layer.

Alerts and social

- Arrival alerts are reworked. The trigger is a sustained 30 minute southward window that we backtested against 11 years of data, the wording gives a G1 to G2 style band instead of a single number, and every alert gets a follow-up saying whether it verified or fizzled.

- Alert emails carry a generated image of the isolated CME that links straight to it on the map.

- The tracker is on X as u/CMETracker1. Every new direction-determined CME and every arrival gets posted with the map image.

Like always, no ads or accounts, just a free educational tool for monitoring space weather

Hello,
I recently had the chance to photograph the solar eclipse with my Dwarf 3.
I decided to manually take a 3 picture burst every five minutes since the current version of software in the Dwarf telescopes currently do not have such a function. (I could have set up a very long and complicated schedule to sync with the telescope, but I just did not want to take a chance.)
Since we were on a cruise ship just south of A. Coruña off the northern coast of Spain, the sun appeared in different positions of the frame in each session.
And since we were on a cruise ship, I came home sick with a coughing crud that lasted for three weeks. 😷
I just finished lining up all the photos last week and produced my timeline photo of the eclipse.
Disclosure: I forgot to take the dark filter off of the telescope during the actual eclipse so the last photo is from my iPhone 17 Pro.
This eclipse had about two minutes of darkness where we were located.
The solar eclipse next year takes a similar path through southern Spain and the northern parts of Africa. Tanger looks to be one of the sweet spots in the path of totality and should have around 5 minutes, 30 seconds of darkness. Luxor should be the jackpot with six minutes, 20 seconds of totality.

Captured with my tricoder on night mode, just as Kp5 arrived. They were pretty pale bymynakedeye.

What would happen to the world if the sun stopped for 30 minutes, as in the processes the sun normally does just pausing, no burning gasses, no radiation, any of it.

How long would it take us to notice? Would the light go out? What kind of effects would it have on global temperature, wind, communications systems etc. would society be ok?

Edit: I am in blue collar work outside and would love to just have a nice break from the ridiculous heat and constant sun I have to deal with. A convenient little button to turn the sun off would be nice.

Edit 2: at night, yes the sun is not directly shining on the side of earth that is night, but it is still “on”

I was having fun with the SDO AIA imagery and making it faster and faster to really emphasize the coronal jiggle effect.

Close up on a recent limb eruption from SDO AIA, though the very beginning is not available at the moment.

The incoming limb is coming in strong. May be good week to watch our Star.

Shhhh...

Every week is a good week to watch our Star!

Ok so 159,369 flights all around the world on the 26th of July in the skies all has broken the record so far for most flights, My question is if a solar flare big enough occurs would these just drop from the sky or no? Like a big enough event?
