“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.”

SpaceNews · Geomagnetic storms cause “mass migrations” of satellitesBy Jeff Foust

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.

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.

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."

Why Northern Lights Viewing Is About To Get More Magical [video]

“Before satellite technology brought us answers, the Northern Lights were a mysterious and unexplained phenomena, long woven into the legends of Arctic communities. Occurring in the polar regions, this colourful light show is caused when particles from the Sun hit the Earth's atmosphere. Around this year or next, it is anticipated that the solar cycle will peak and a period of more intense and complex Northern Lights will follow…”

Why has the sea surface temperature ( #SST ) increased so fast this past year and a half? Are #climate models missing key factors?

The article provides a good overview of some of the compounding effects (SO2 aerosols, #solarcycle 25, #water vapour from the Hunga Tonga #eruption and El Nĩno), but is it enough to explain what’s happening? Either way, it’s an enormous amount of heat.

The New Yorker · Why Is the Sea So Hot?By Elizabeth Kolbert

i went on a bit of a lap around the #solarCycle pool cuz @czottmann posted a video talking about solar activity (#amateurRadio nerds get hype!) and apparently this part of the solar cycle is when the auroras get really wild:

space.com/why-auroras-will-be-

and i've seen them from my father's place when he lived in MN, i always loved that i could actually see the milkyway galaxy around us from Hastings, MN.

Space · The next 4 to 5 years will be the best time to see the northern lights this solar cycleBy Daisy Dobrijevic
Continued thread

So evidently this was a part of the southern polar crown prominence (PCP) that lifted off yesterday morning. And #TIL that these structures decay away by the time of solar maximum, so although we’re therefore not quite at the maximum of #Cycle25, it’s also not long from now.

More about the phenomenon of PCPs: link.springer.com/article/10.1

SpringerLinkOn the Structure and Evolution of a Polar Crown Prominence/Filament System - Solar PhysicsPolar crown prominences, that partially circle the Sun’s poles between 60° and 70° latitude, are made of chromospheric plasma. We aim to diagnose the 3D dynamics of a polar crown prominence using high-cadence EUV images from the Solar Dynamics Observatory (SDO)/AIA at 304, 171, and 193 Å and the Ahead spacecraft of the Solar Terrestrial Relations Observatory (STEREO-A)/EUVI at 195 Å. Using time series across specific structures, we compare flows across the disk in 195 Å with the prominence dynamics seen on the limb. The densest prominence material forms vertical columns that are separated by many tens of Mm and connected by dynamic bridges of plasma that are clearly visible in 304/171 Å two-colour images. We also observe intermittent but repetitious flows with velocity 15 km s−1 in the prominence that appear to be associated with EUV bright points on the solar disk. The boundary between the prominence and the overlying cavity appears as a sharp edge. We discuss the structure of the coronal cavity seen both above and around the prominence. SDO/HMI and GONG magnetograms are used to infer the underlying magnetic topology. The evolution and structure of the prominence with respect to the magnetic field seems to agree with the filament-linkage model.
