And if it takes off, it could become a source of income! Win-Win-Win!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?
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.

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.

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

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:

As a result of this event, a minor G1 geomagnetic storm is predicted to occur on June 28 when a component of the CME grazes the Earth's magnetic field. In the meantime, on June 27

I saw a G4 warning this afternoon from NOAA and got all excited thinking we might have a repeat like the last event. I ended up disappointed when I saw it occurred around 11 am EST :(
I was going to post about it, but then I refrained because I did not know how to present the data; your posts are so much better!
From the Royal Observatory of Belgium Solar Influence Data CenterHi All! Join me LIVE today at 11:00a PDT (18:00 UTC) for an informal briefing on the surprise (but not so surprise) G4 storm hitting now. This is the expected glancing blow from one of the filaments launched a few days ago, but it has arrived much faster and is stronger than predictions. See what that means for aurora photographers, radio amateurs, and GPS users as we move through the rest of this week, especially since we have another, smaller storm coming over the next few days.
I am making this briefing available to the public, but you Patrons have priority in getting your questions answered! So please feel free to join the You Tube chat directly by clicking the link below, or post your questions here and I will check them during the Q&A.
Solar flaring activity was at low levels, with a few C-class flares recorded in the past 24 hours.
The largest flare of the period was a C3.2 flare, peaking at 14:40 UTC on June 28, associated with an active region (AR) behind the east limb (N10E89), which is currently rotating onto the disk. NOAA AR 3723 (beta class), which produced only one low-level C-class flare in the last 24 hours, appears to be shrinking and reducing in complexity. Other regions on the disk have simple configurations of their photospheric magnetic fields (alpha and beta) and did not show any significant flaring activity.
Solar flaring activity is expected to be at low to moderate levels over the next 24 hours, with C-class flares probable and a chance of M-class flares.A faint partial halo coronal mass ejection (CME) was observed in SOHO/LASCO-C2 at around 00:48 UTC on June 28, directed towards the southeast from Earth's perspective. This CME is likely associated with flaring near NOAA AR 3730. Given the source's location close to the disk center, an impact at Earth is possible from late on July 1st.
This ICME will likely interact with the one from June 27 on its way to Earth, although the prediction of its arrival remains with low confidence. No other Earth-directed CMEs have been detected in the available coronagraph imagery over the past 24 hours.
Over the past 24 hours, the greater than 10 MeV GOES proton flux was at nominal levels and is expected to remain so for the next24 hours.
The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, remained below the 1000 pfu threshold. It isexpected to remain below the threshold during the next 24 hours. The 24 hour electron fluence was at normal levels and is expected to remain at these levels for the following 24 hours.
