SatNet LEO Group 20 and the Long March 8A (CZ-8A) upper stage from this morning over South America. The objects surrounding the upper stage are most likely remnants of the passivation process.

A two hours light-curve from EXPRESS AT1 (Ekspress-AT1) #39612 recorded last night.

@DoimoManu That appears to be an airplane in the foreground.

@s2a_systems What are those collisions?

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.

and the corresponding light curve

@OrbitalFocus Welcome back!

Jielong 3 launch, Feb 12 Interesting informational gymnastics by Space-Track made things a little confusing but there may have been a problem with the release mechanism for one of the sats #027" target="_blank" rel="nofollow noopener">orbitalfocus.uk/2026#027

@s2a_systems What are the two very faint objects that are following the satellite in front?

A short time lapse of the fragmentation event on LUCH (OLYMP) #40258 that took place today, 2026-01-30 from 06:09:03.486 UTC.

@BobnapatorA ~36'100 km

@s2a_systems Which altitude?

@cibrigi47428 Coincidence. The object is part of a long-term study on space debris that we are currently conducting.

@s2a_systems What was the reason this satellite was even being tracked with a telescope? There’s 10’s of thousands of satellites in orbit. We don’t bother visually tracking any of them unless there’s a reason and this one just happened to be sunlit on the night side of earth. Planned event.

@RAH335 Coincidence. The object is part of a long-term study on space debris that we are currently conducting.

@s2a_systems great shot. How were you able to stare at it prior to the event?

@NathanParrott16 The cause of the incident is not yet clear. The bright object at 06:14:16 is just a bright star in the background and has nothing to do with the event.

@s2a_systems Was that a collision? It seems to have passed a very bright object right at the point of the breakup.

and the corresponding light curve

LUCH (OLYMP) has started to tumble in its graveyard orbit tonight. Additional objects around the satellite can also be visually detected. An analysis of our photometric data is currently in progress.
