A 10-minute stack from the Ecliptic Camera looking south. I thought this long streak was a meteor, but it's Ryanair flight RYR8BT, a Boeing 737-800 (9H-QAD, flown by Malta Air for Ryanair), descending from 12,700 to 11,000 feet at about 310 knots on its way into Stansted, where it landed at 01:13. It passed within 3 km of the camera, and the curve at the bottom is it swinging round as it came almost overhead. Where it came from isn't in the flight data we have; it was heading north near Gatwick when the recording starts.
The trail runs across two consecutive 60 second exposures, and a meteor lasts less than a second. It shows the same faint dashing as the anti-collision strobes on the TUI flight an hour later. The ADS-B flight history from adsb.fi puts RYR8BT at a bearing of 188 degrees and 14 degrees up at 00:01 UTC, within about 2 degrees of the lower end of the trail. The sun was 39 degrees below the horizon, too dark for a satellite.
