Resharing these here to hopefully prevent as much misinformation and/or confusion as possible.
Solar flares and coronal mass ejections are not phenomena that can be referenced interchangeably. They are completely different phenomenon with completely different impacts. ☀️

Join Space Weather Unplugged for a chat with a space weather professional, Sara Housseal. Let's find out more about space weather models and their use!
Hope to see you on February 22 at 8 PM EST. That's February 23, 0100 UTC in space weather time.

Yesterday's sun! The chunky sunspots are heading around the bend and it's looking awfully quiet in the other hemisphere.

Fun Fact: Solar and Heliospheric Observatory (SOHO), the sole provider of coronagraph imagery from L1 along the Sun-Earth line, was originally planned for a 2 year mission in Dec 1995, or 730 days. As of 23 Jan 2025, SOHO is on mission day 10,646! ☀️🛰️

Nice reminder of how the semantics of active region complexity don't always mean much of anything when it comes to possible flare activity.
3961 & 3964 have been the most complex & likely of flare activity, yet a benign area blasted a long duration M3 flare w/ a southward CME. ☀️

Considering we have yet to see much of any flare activity from this region to provide additional analysis, without computational analysis I don't think we can confidently say how caged it truly is, or isn't.

AR3961 (south center) currently has the best chance for activity with the highest flare probability of all regions on the disk at 45% for M flares & 10% for X flares. This will be the region to keep an eye on over the next few days as any eruption would likely have an Earth directed component. ☀️

Big, scary coronal hole with concerningly fast solar wind that could wreak havoc on Earth where? 🧐 ☀️

Clear skies today with temperatures in the 30s (℉) gave us an opportunity to record an interesting development on Earth's Sun. "Fast-growing sunspot 3964 didn't even exist yesterday," reported Spaceweather .com. "Now it is as big as two Earths and poses a threat for strong flares."

Although AR3964 will continue to rotate into a non-favorable position in the event it ever launches a CME, this is still a region to watch as of right now. 💥
After abruptly appearing on the disk, indicating its potential for activity, it just released an M7 flare, no CME. ☀️

Due to the Parker Spiral & travel time, the CH rotates ~40° passed CM before connection, giving the impression that's the form of the CH that's currently impacting Earth. This is not the case, meaning change in a CH beyond CM has little to no influence on what Earth sees.

Second, the fast solar wind from a CH that reaches Earth is that from when it is near CM, roughly three days prior to connection, not that of its more westward position.

Although they do change in size, be mindful of perception & angle.
CHs are viewed via the corona, which is the outer most layer of the Sun, thus when looking at a CH from any view point other than dead center, there is a lot of material/plasma that can obstruct the view.

Let's clear up two common misconceptions when it comes to coronal holes (CH). 🧵
First, do not be fool into thinking the size has changed drastically, growing from east to central meridian (CM) and then shrinking from central meridian westward. ☀️

With new active regions appearing, we will have to keep a close eye on the eastern portion of the Sun.
Flare activity is quiet, for now, but that can switch up quick. 👀☀️

The fast solar wind from the western most, finger-like extension of the coronal hole is reaching Earth now and should continue to ramp up as the entirety of the coronal hole rotates westward.
This could enhance geomagnetic activity over the coming days. ☀️
