A 10-minute stack from the Ecliptic Camera looking south. What looks like a very long meteor is an airliner, TUI flight TOM19V, a Boeing 737-800 (G-TAWX), descending from 10,100 to 8,600 feet at about 370 knots on its way into Stansted. It came up over western France from the south, probably from Spain or the Balearics; the flight data doesn't say which. It stayed on the same compass bearing, 198 degrees, for the whole two minutes while rising from 6 to 43 degrees above the horizon, because it was flying almost straight towards the camera. That is why the trail is vertical.
The trail runs across two consecutive 60 second exposures, and a meteor lasts less than a second. The top of the trail is a regular train of double dashes, the anti-collision strobes, and the solid, brightening lower part is the landing lights coming towards us. The ADS-B flight history from adsb.fi puts TOM19V exactly there between 00:51 and 00:53 UTC. It can't be a satellite either: the sun was 39 degrees below the horizon, and satellites don't flash.
