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. ☀️

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? 🧐 ☀️

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. ☀️

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.

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. ☀️

In case you come across a bunch of hype about a "big hole in the Sun", it's really not that serious and is a normal part of the solar cycle, as always.
Wait until we get to solar minimum and coronal holes take up nearly half of the Earth-facing disk at times. ☀️

As a majority of the regions on the disk continue to decline and/or rotate off with no replenishment, background x-ray flux has dipped into B level.
Not completely unusual, but shows how easily activity can change no matter how good or bad things look on any given day. ☀️

The anticipated CME from the M4 flare on the 6th has little to no plasma ejection appearing in coronagraph despite possibly a small, weak puff to the north. Little to no activity is expected as a result at this time.

Update on underperforming CME activity:
The possible glancing blow CME from the 4th appears to have arrived around 04Z today. Despite providing a decent jump to wind speeds, magnetic field connection has been weak, so G1 has not been reached. 1/2 ☀️

CME in question, which is directed mostly to the southwest but does create a faint partial halo signature, indicating an Earth-directed component is possible.

New G1 Watch for the 6th following analysis of the CME associated w/ the long duration C7 flare from AR3939 on the 4th.
While I personally wouldn't expect much of anything from this on its own, the environment is already disturbed, so it wouldn't take much to see G1 conditions. ☀️

Despite expecting a CME around the same time, I would argue the current enhancement in the solar wind/magnetic is due to the fast solar wind from large +CH05.
Are we finally reaching the point in the solar cycle where coronal holes can be a reliable source of activity again? ☀️
