Solar activity remained high throughout May.
June 2, 2023: If you’re a satellite, this story is important.
A series of geomagnetic storms in 2023 has pumped terawatts of energy into Earth’s upper atmosphere, helping to push its temperature and height to a 20-year high. Air surrounding our planet is touching satellites in low Earth orbit and dragging them down.
“Blame the sun,” says Martin Mlynczak of NASA Langley. “Increasing solar activity is heating the top of the atmosphere. The extra heat has no effect on weather or climate at Earth’s surface, but it’s a big deal for satellites in low Earth orbit.”

Mlynczak is an expert on the temperature up there. For 20 years he has been using the SABER instrument on NASA’s TIMED satellite to monitor infrared…

I must say I find it extremely hard to believe that significant changes to one part of the atmosphere haven’t effects on the rest.

The TCI is not only ahead of schedule compared to SC 24, it’s already reached higher than the max of SC 24.

As if the sun had respect for human hubris.
OK, this something I don’t know too much about to comment: BUT will it have an effect on Wooden Satellites? The Northern lights may take a new meaning. https://www.techspot.com/news/98930-japan-put-wooden-satellite-orbit-next-year.html
Does this mean that some of the space junk will be de-orbited as well? Every top-of-the-atmosphere cloud has a silver lining.
OMG! the CO2 from my F-150 and the backyard grill are going all the way to the sun and heating it too!!
Maybe unrelated, but anyway…
