I Think I can now identify the source of this fuel vent as the rocket stage from the 19:48 UTC (March 12) launch of SatNet LEO Group 20 from Wenchang. Here is some quick astrometry I got from the movie: 99999 26 999X 0000 G 20260312211108000 18 75 0245590+177870 57 99999 26 999X 0000 G 20260312211232000 18 75 0247562+292140 57 99999 26 999X 0000 G 20260312211238000 18 75 0250053+305220 57 99999 26 999X 0000 G 20260312211246000 18 75 0250149+320170 57 99999 26 999X 0000 G 20260312211300000 18 75 0250276+348050 57 San Mateu, 40.4653 N, 0.1789 E Very approximate orbit (quite some leeway in inclination): 1 99999U 0000000 26071.88402778 0.00000073 00000-0 50000-4 0 07 2 99999 47.3035 51.8581 0006423 288.7000 142.8167 14.55905529 01 This brings it near Wenchang at 19:48 UTC. - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam_at_langbroek.org launchtower: http://launchtower.langbroek.org Station (b)log: http://sattrackcam.blogspot.com Twitter: _at_Marco_Langbroek ----- Op 13-3-2026 om 10:53 schreef Marco Langbroek via Seesat-l: > > Hi all, > > yesterday 12 March at around 21:10 UTC, Spanish meteor cameras captured what is > clearly a fuel vent. > > the event was in the southern sky, passing some 12 deg south of the Pleiades as > seen from San Mateu at 40.465 N, 0.179 E. > > I so far cannot find any candidate for it.
