First images of the Sun's south pole!

Solar Orbiter is the first space probe to look at the Sun's poles – and finds the magnetic field there in a state of turmoil. The Sun's magnetic field is currently undergoing a flip. During its latest flyby of the Sun at the end of March this year, the Solar Orbiter space probe had its first clear view of our star's poles. First images:

This image shows a magnetic field map from Solar Orbiter's Polarimetric and Helioseismic Imager (PHI) instrument, centred on the Sun's south pole. Blue indicates positive magnetic field, pointing towards the spacecraft, and red indicates negative magnetic field.  On an off-set concentric grid with an overall yellow base color, blue and red bent stripe-like structures are sprinkled across the field of view. © ESA & NASA/Solar Orbiter/PHI Team, J.

"They say sunspot maximum is the golden age for HAMs..."

Well, I'm now two summers deep into this relentless solar burping and D-layer thickening — and I respectfully disagree.

Maybe the solar minimum is even worse?

Either way, I’d like to file a complaint with the universe. I want my money back :D

Almost caught up with the Alzabo Soup podcast and the question arose as to what ta call the narrator of Short Sun. It's surely been suggested, but:

Hilksorn.

I love this quote from Book of the Short Sun:

"Who can plumb the mind of the Outsider, and search out all his ways? Our treasures are his dross; our gods, his toys."

It reads like a psalm to me. It's beautiful.

"2025 Solar Storm" generally refers to the expected peak of #SolarCycle 25.

Solar Cycle 25 is the current solar cycle, and scientists predict its peak activity, or "solar maximum," will occur around 2025.

I got my #amateurradio license in 2018, during the boring minimum between #solarcycle 24 and 25. As a technician class operator at that time, the majority of my HF privileges were on 10m. I made only a handful of HF contacts that entire year before upgrading my license in 2019 and making the switch to 20m and 40m.
It's incredible, now, jumping on 10m and seeing spots throughout the Americas and across Europe.
Looking back, I wonder how different my initial perception of #hamradio might have been if I had gotten my license further into a cycle...

“As a result of this low skill in our forecasts, #SpaceX saw 20 kilometers of position error in their one-day computations. If we’re uncertain in where our spacecraft are by 20 kilometers, then you can throw collision avoidance out the window.”

Hey Folks! There's another cool #Aurora northern lights show tonight!!!

Not as big as the solar storm in the spring, but still a pretty good one. Make plans to go find somewhere dark and look at the northern horizon (in the northern hemisphere). Remember, to your eyes it might just look like city lights, but to your phone on night-mode (long exposure) it will look a lot cooler.

There is an extraordinarily long still taking place for almost the past full day. This graphic shows the flux, the highest in the current , and this is definitely also the longest flare.

For this means that we won't be able to use these data, as every one of these protons will leave a trace on our CCD detectors and that's just too many. So a day of data lost 😞

Measurements of solar protons by th GOES satellites. Red curve shows all protons with energies >10 MeV. This flare has been going on for 24h now and isn't yet over. From the NOAA Space Weather Prediction Center.

Coming next, when I get around to it: solar influences. I have several years of data from the period between the minimum to the maximum of the current solar cycle. Even at my moderately light-polluted site, I can see the influence of solar activity on night-sky brightness here. #SolarCycle #Cycle25 #Sun

In the line of fire...

Biggest solar flare since 2017 erupts from sun and Earth is in the firing line

On Oct. 3, the sun released the most powerful solar flare this solar cycle, a colossal X9.05 eruption.

SUNSPOT NUMBERS CONTINUE TO INCREASE: Last month, the average sunspot number exceeded 200 for the first time in 23 years, significantly exceeding official forecasts. The surge could be a harbinger of strong solar activity for years to come. It's also great news for sky watchers as we enter the equinox aurora season. Spaceweather.com has more.

Solar Cycle 25 continues the trend of much higher sunspot activity than originally forecast, with the latest sunspot number for July (196.5) nearly double the predicted value (106.4).

Closed loop? Reused #SolarPanels to power solar panel #recycling facility

Sean Wolfe
7.26.2024

"#SolarCycle, a solar recycling company, has installed an on-site solar farm made of reused solar panels that will power its industrial solar panel recycling facility.

"The reused panels come from decommissioned utility-scale solar farms and residential installations across the United States. SOLARCYCLE says the project serves as a model of how to power an industrial facility through renewable energy as the US ramps up domestic manufacturing capacity. It will also help to build a fully closed loop, ultra-low carbon solar industry in America.

"The 500KW system made from around 1,000 reused panels will provide around 50% of the electricity SOLARCYCLE uses to power their advanced recycling factory in #OdessaTexas. SOLARCYCLE’s plan is to expand this secondhand power plant to continue to generate more of the company’s energy demands, including its facilities in #MesaArizona, and #CedartownGeorgia. Two of SOLARCYCLE’s customers provided a significant percentage of the secondhand solar panels in use — #Ørsted from their own Texas utility-scale operations and #Sunrun, from their residential operations.

[...]

"Earlier this year, SOLARCYCLE announced it would invest an estimated $344 million into a new #SolarGlass manufacturing facility in #CedartownGeorgia. The company said it would be the 'first-of-its-kind' in the United States to use recycled materials from retired solar panels to make new solar glass.

"The facility will be located in Cedartown North Business Park, a Georgia Ready for Accelerated Development (GRAD) certified site in Cedartown. The plant, which will be the first of SOLARCYCLE’s facilities to manufacture glass in addition to recycling solar panels, was scheduled to begin construction this year and is expected to be operational in 2026.

"SOLARCYCLE currently operates two solar panel recycling facilities in the United States and says its recycling technology allows it to extract up to 95% of the value from used solar panels. SOLARCYCLE’s new plant in Georgia will make the company one of the first manufacturers of specialized glass for crystalline-silicon (c-Si) #photovoltaics in the U.S., with the capacity to make 5 to 6 GW worth of solar glass every year, it said. The glass will be sold directly back to the domestic solar manufacturers.

"Solar photovoltaics are often recycled the same way as glass, cars, computer monitors, TVs, or lighting, but the process only recovers about 80% of PV materials. Nonspecialized recycling is one of the challenges to achieving a circular economy for solar photovoltaics.

"While the moral incentive to recycle solar panels is clear, little financial incentive exists today. Recycling a solar panel ranges in cost from $20 to $30, while dumping the same panel in a landfill runs $1 to $2 – but SOLARCYCLE believes the cost to #landfill to be much higher when factoring in logistics costs."

The current #SolarCycle25 started in 📆 2019. It is not expected to end for another six years but the first signs that the next #SolarCycle is beginning have been spotted by researchers from the University of #Birmingham and presented at the @royalastrosoc National #Astronomy Meeting in Hull. "We're likely seeing the first traces of Cycle 26, which won't officially start until about 📆 2030." sciencedaily.com/releases/2024
