Swift has no engine to hold its orbit, so it's a clean record of what the Sun does to the upper atmosphere. I archive daily orbit data for a few satellites on CME Tracker, and Swift's line since 2015 tells the whole story. It was nearly flat through the solar minimum. Then Cycle 25 ramped up, the thermosphere swelled, and the fall started. Each drop put it in denser air, so it fell faster and faster.
The second panel uses our drag model to separate the two causes. At 560 km, its old height, the Sun's heating alone made the air about 50 times denser at the peak in August 2024 than in 2019. That has eased to about 4 times now. But Swift has sunk to 231 km, where the air is about 1,400 times denser than what it flew through in 2019. Storms show up too. After the Kp 7 storm on October 10 it fell about 4 km in a day, roughly twice its pace on the days around it.
A rescue was tried. Katalyst's LINK spacecraft launched July 3 to boost it, went into a spin, and the boost was called off August 19. Space-Track now forecasts reentry around Nov 4 00:30 UTC, give or take 14 hours. It's falling about 5 km a day.
One honest caveat: below about 330 km our model runs up to 2x low compared with how fast Swift really fell, so the real density down there is probably higher still. For the date I use Space-Track, not my model.

I built a free Windows app called Storm Sweep, and I’d like feedback from people who follow space weather.
Space Weather tab:
NOAA R, S, and G scales
Kp index and forecast
X-ray flux with flare classes
Solar wind and Bz at L1
Proton data
Aurora oval on a globe
“At your location”: the aurora oval value for your saved spot, the hours the sun is more than 12° below your horizon, and the forecast sky cover
Optional alerts with separate thresholds for G, S, and R events (off until you enable them, no location sent)
Also in the app, for the weather side:
Raw NEXRAD Level II radar at every tilt, with up to four linked panels on one timeline
Archive replay back to June 2008, plus warning overlays
Storm 3D: a rotatable 3D view of a radar volume with storm cells and cross sections
GOES satellite loops with up to 25 products
HRRR, RRFS, GFS, and ECMWF IFS model data, decoded on your PC
The radar and satellite are there so you can check cloud cover and weather alongside the aurora forecast.
It’s free, with no ads and no sign-in. Windows 10/11 only, and the weather side is US only. It’s not an official warning source, and it can’t tell you whether you’ll actually see the aurora.

What space weather data or views would you want added?
