Sol (Sun) and its phenomena

Me too! But I also understand that some people don't have a super fast Internet connection, so finding a compromise would be good, I think.

@Puma, how about considering starting a Substack page, where you make your full posts with pictures and all, and those of us who are interested can subscribe? That way, you are still recording it daily and all (which many of us appreciate!), AND we get to discuss it here. How does that sound? Win-win?
And if it takes off, it could become a source of income! Win-Win-Win!
 
SOLAR CYCLE 25 ACTIVITY REPORT JUNE 10_2024

X-FLARE

An X1.5 flare was recorded at 11:08 UTC from the AR3697 region which is already on the far side of the sun so it was partially eclipsed by the edge of the star, that is, it could have been brighter than observed or higher than X1. The explosion did not record a coronal mass ejection heading to Earth, however, a Strong R3 radio blackout over Africa and Europe was recorded.
During the night, this region (AR3697) erupted with a strong M9 flare (video from Dr Keith Strong on twitter), wich produced as usual a radio blackout and more importantly also generated a proton event.

A polar cap absorption event affecting shortwave radio inside the Arctic Circle was recorded as aftermath from strong M9 flare.

Around 17:00 UTC on June 10 the edge of the CME from the M9 event hit the Earth's magnetic field.

The solar wind speed increased to 428 km/s, the Bz component of the interplanetary magnetic field (IMF) points to the south which announces the presence of auroras while the Bt value is 14.23 nT, which indicates a strong solar magnetic field.

Let's see if the impact of the CME and the strong IMF have any impact on volcanoes or seismic activity.
The total number of sunspots is now on the order of 148 of which 35 are grouped into 9 active regions, as shown below:

AR370914230 By
AR3710440 B
AR3711360 B
a (alpha) B (beta) y (gamma) d (delta)

We see that most of the active regions have stable magnetic fields (alpha & beta) while AR3703 and AR3709 have unstable magnetic fields (beta-gamma) that harbor energy for M-flares. This is why the NOAA forecast indicates that there is a 70% chance of seeing M-class flares, in fact, during the transition from AR3697 to the west, 4 M-class events were observed.



 

The sun's magnetic field is about to flip. Here's what to expect.​


sun flip.jpg
The sun is on the verge of a significant event: a magnetic field reversal.

This phenomenon happens roughly every 11 years and marks an important stage in the solar cycle. The shift in polarity indicates the halfway point of solar maximum, the height of solar activity, and the beginning of the shift toward solar minimum.

The last time the sun's magnetic field flipped was toward the end of 2013. But what causes this switch in polarity, and is it dangerous? Let's take a deep look at the sun's magnetic field reversal and investigate the effects it could have on Earth.

To understand the magnetic field's reversal, first, it's important to be familiar with the solar cycle. This approximately 11-year cycle of solar activity is driven by the sun's magnetic field and is indicated by the frequency and intensity of sunspots visible on the surface. The height of solar activity during a given solar cycle is known as solar maximum, and current estimates predict it will occur between late 2024 and early 2026.

 
SOLAR CYCLE 25 ACTIVITY REPORT JUNE 15_2024

In recent days a phenomenon of solar tornadoes occurred. Solar tornadoes are different from those of the Earth because while those that happen on Earth are due to different atmospheric pressure sources, in the sun the magnetic difference is what causes the movement. A solar tornado is the size of several Earths combined.

According to solar science, the tornadoes occur at the poles, where lines of magnetic force point out into space, these tornadoes reach speeds of up to 200 thousand kilometers per hour.

Keith Strong wrote on X:

SOLAR TORNADOES? You are seeing here huge columns of relatively cold material (50,000K) suspended by magnetic fields in the 1MK (millions of kilometers) solar corona. The magnetic fields insulate the cold plasma but also moves creating what looks like a dance. Some call these tornadoes, but they aren't.

HERE & HERE you can see other tornadoes
The total number of sunspots is now on the order of 117 of which 62 are grouped into 7 active regions, as shown below:

Sunspot AR3712 is of special interest given its unstable beta-gamma-delta magnetic field that commonly produces strong flares that can reach X-class and for this reason NOAA forecasts a 50% chance of M-class flares and 10% for X-class in the next 24 hours. Sunspot 13712 has been the most active region, It appeared in the southeast region of the solar disk last June 12 and so far has generated a number of C-class flares and three M-class solar flares: one M2.4 on June 14 and two almost simultaneous M1.3 on June 15. These flares recorded minor R1 radio blackouts in Southeast Asia and in the Indian region respectively.​
A POTENTIALLY DANGEROUS SUNSPOT: Only a few days ago, sunspot AR3712 didn't exist. Now it's 8 times wider than Earth and growing fast. This morning in Austria, Michael Karrer photographed the sunspot crackling with activity. SpaceWeather.com
UNEXPECTED CME IMPACT: A CME hit Earth's magnetic field today, June 15th (1157 UT). The unexpected impact sparked a minor G1-class geomagnetic storm, which could wax and wane for the rest of the day. SpaceWeather.com

This unexpected CME impact caused the solar wind stream to reach 457km/sec which is an elevated level, while IMF: Bt (strength) reached 13nT.

Subsequently, at 13:10 UTC an increase in Active Geomagnetic conditions (Kp4) was recorded and at 13:29 UTC a minor geomagnetic storm G1 (Kp5) occurred, which subsided around 15:00 UTC.

"This is probably due to the coronal hole (see earlier tweet) that is on the solar disk. Will the storm intensify possible but unlikely - not a very large coronal hole" Published on X the Solar Physicist Keith Strong.

If this was the case, what caused the solar storm was not a CME but a high-speed solar wind stream from a coronal hole. And in my opinion this is correct, so there is no solar conspiracy.

Stay tuned

Do you remember the AR3664 region? It is about to return to the solar disk. In mid-May this sunspot produced a series of X-class flares and at one time reached a size of 2400MH.​

X8.7 at 16:51 UTC from AR3664 the flare produced a Strong R3 radio blackout over Americas
20240514_111233.png

AR3664 now carries the designation AR3723 and has produced a strong M9.2 flare at 13:01 UTC on June 23 which produced a Moderate R2 radio blackout over Atlantic Ocean and West Africa

The flare was partially eclipsed by the Sun's curvature, so it could have been an X-class flare.
SOMETHING FLARE-Y THIS WAY COMES: Old sunspot AR3664 might not be dead, after all. It's returning today for a rare third trip across the Earthside of the sun. Usually such a superannuated sunspot would be a decaying corpse. Instead, we're getting an explosive active region:​
SpaceWeather

So, we are possibly in for a week where AR3723 has some surprises in store. At the moment this sunspot has a stable magnetic field, which will change once it is better positioned in view of the instruments.

How is the sunspot situation at the moment?

The total number of sunspots is now on the order of 139 of which 92 are grouped into 11 active regions, as shown below:

Solar activity has been at high levels for the past 24 hours thanks to the M9.2 flare. The geomagnetic field has been quiet to unstable for the past 24 hours and FMI total reached 12 nT at 07:30 UTC on June 23, after several days of staying below 5nT.​

This is basically what we should be aware of at the moment. Thank you
