An unfavorable orbit and a lot of Saharan dust over Central Europe made observation difficult. Nevertheless, we were able to record about 90 minutes of today's PROBA-3 pass from Switzerland. PROBA-3 CSC shows currently a repeating rotation pattern of approximately 1150 seconds.

Highly elliptical orbit: A time-lapse of ~6.5 hours flight time of the PROBA-3 satellites. During this time the satellites climbed from ~6’700 km to ~57’000 km altitude. With the corresponding effect on the image scale on the sensor. Recorded from South America on 2025-01-26, from 01:55 - 08:29 UTC.
