This report from February 4, 2025, details a period of low geomagnetic activity on Earth despite significant solar flare activity. While KP indexes remained low, multiple M-class flares were recorded, primarily from sunspot group 3981. The presenter warns of a high probability of further M-class and potential X-class flares, with a coronal hole expected to face Earth within 48 hours.

Ladies and gentlemen, we've had a very quiet day here on Earth.
We've had very little solar activity of any kind that includes
solar winds or any type of plasma or coronal mass ejection impacts.
If we look at our KP indexes here,
first our Boulder KP index, very little has happened
along with all the other indexes. We do have three hours of geomagnetic
disturbance that showed up on our college index,
which is quite strange because I don't see
any plasma or solar winds striking Earth all day long.
Headed over to our GOES X-ray flux. What do we see?
Well, we've got a lot coming this way.
A lot of these flares that you see here are Earth-directed,
and thus far today we've had
five strong M-flares, some not so strong,
but a couple that were very impressive.
And we all know we had the 8.88 M-flare yesterday,
almost an X-flare.
All right, heading over to SpaceWeatherLive.com.
The big flare of the day is the M4.7 flare that peaked around
11.21 UTC time for about 5.21 this morning central time.
Now, after that, we did have another M flare
that's not been assigned a sunspot group thus far.
It could mean it was a filament eruption.
But we will be able to pick that up
on our X-ray absorption prediction center.
Now, we have only two sunspots
that have generated M-class solar flares thus far today,
3981, which has been giving us all the trouble,
and believe it or not, 3977,
which seems to have actually expelled an M-flare and then dissipated.
Here is 3977 generating that M1.2 flare
that peaked at 518 UTC time, so about 1018 last
night central time.
Currently, we have a 20% chance of having
an X-class solar flare today, an 85% chance
of having an M-class solar flare,
which that ship has sailed, and we've been running a
steady C baseline now.
Back to a steady C baseline,
so I believe that that should be 100%, but we'll go with 99%.
Heading over to our HMI intensogram, well,
we can get a good look at 3981 directly earth-facing.
It looks like a really complex sunspot group.
You can see it's red, which means it's a delta-class sunspot group.
Ones that are orange or beta gamma,
and the green ones are simple sunspot groups.
Now, what's strange is that AR3977
was located right here.
Now, I thought it might be this sunspot group on the limb here,
but I did some more checking,
and as y'all will see, it actually expelled
an impulsive solar flare and then dissipated completely.
I really don't remember
that happening all within just a few hours time.
I want to assure you that of course 3981 all of this are earth-facing
and we are in the strike zone for
sure and it is well crackling with M-class solar flares
and it could push out an X-class solar flare
in an associated coronal mass ejection at any time.
Over to GOES Solar Ultraviolet Imager 195 angstroms.
I don't see the M-flare that hasn't
been assigned a sunspot group
unless this is it right here.
I really don't believe it is.
So I'm going to say that we can't really locate
that M-class solar flare
that's reported on our GOES X-ray flux.
We see how busy this area is,
is with all the sunspot groups right here.
We also see that we have
a coronal hole coming around to be earth-facing
within probably the next 48 hours.
Over to our D-region X-ray
absorption prediction center.
Well, that was the large flare of the day,
the 4.7, and this is the mystery flare here.
Not quite sure what sunspot group it came from.
I'm guessing it came from 3981.
That would be what was logical.
And everyone's been getting their dose of at least
a C-flare all day long, all around the globe.
Headed over to SDO HMI magnetogram image.
We're getting some really, really recent pictures here.
Look how complicated this area is up here.
It's going to be a miracle if it doesn't expel an
X-flare that's directly earth-facing. It really is.
It looks like we might have some sunspot
groups coming around the limb as well.
You can't really see the coronal hole on SDO here.
This was taken today at 19:30 UTC time,
so this is the latest and greatest. You can see that
Sunspot groups on the limb have already made their way around.
We'll take one last look before we go.
Now, today we had solar winds start out
at about 500 kilometers per second
and go all the way down to 400 kilometers per second.
That was because of this coronal hole here that was Earth-facing.
We actually saw 700 kilometers
per second solar winds yesterday.
Here we are with all of our different sunspots here,
and if we count 77 that seems to have
disappeared in this sunspot group here,
we have a total of nine sunspot groups
earth-facing. We can see one coming around the limb here.
It's easy to see the coronal hole that
will soon be earth-facing,
and this was again not taken as recently as the last picture.
It was just taken last night at 8:06 Central Time,
but it gives you a great idea of what's going on.
With that said, God bless you and yours, folks.
Lots of coronal mass ejections inbound.
We should see a lot of solar weather over the next three or four days,
and that could continue depending on,
well, how these sunspot groups work out.
God bless.
