Path on the sky: az 7° el 23° → az 2° el 15°, 28 s

Evidence:
✓ coherent track for 27.8 s, 101 points, within 1.4 px of a smooth path
! angular speed along the path: 0.48°/s on average, 0.12 to 1.08°/s over 1 s windows (start to end in a straight line: only 0.33°/s)
! changes direction: 163° in all, 0 sharp turn(s) of 60° or more, turning at up to 25°/s (satellites and aircraft: ~0°)
· off a great circle: up to 2.9° (RMS 1.2°); an orbit or a straight flight stays below ~2°
· 6.69 px/s in the image, peak brightness 202
✗ no catalogued satellite within 12 px (nearest: ONEWEB-0296 (78.4px))
✗ no ADS-B aircraft within tolerance
· a satellite in this direction is sunlit above 521 km
Constellations in view: Aquila, Camelopardalis, Cepheus, Corona Borealis, Draco, Hercules, Lyra, Sagitta, Serpens, Ursa Maior, Ursa Minor

Detected and analysed with SkydomeWatch: every object is compared with catalogued satellites (CelesTrak) and ADS-B aircraft (adsb.lol); "unidentified" only means that neither explains it.
