PAZ orbital insertion rocket motor firing right after sunset
|Rocket motor burn seen towards west of Tromsø right after sunset on Feb 22nd 2018 at 18:12 local time. Most likely from the recently launched PAZ satellite.
The most likely explanation is that this is a orbital insertion maneuver for the radar satellite PAZ, which was launched on February 22nd, 14:17 UTC using a Space X Falcon 9 booster, approximately three hours before I saw the rocket motor burn. The ascending node PAZ is approximately at 18 local time, which is consistent with the observation.
