Daily brief · Monday, 19 October 2026 (UTC)
19 Oct: 7 military satellites changed orbit, 0 closing on others, 2 launches, 13 clusters over conflict zones ahead.
Countries busier than usual
0A country's last 7 days against its own normal (the 90 days before, once there are 28): at least twice its usual week and well outside chance.
No country ran well above its normal this week.
Military satellites that changed orbit
7Confirmed by the next public orbit update.
Military and unclassified satellites closing on others
0In nearly the same orbit as another object, and getting closer.
None found on this day.
Geostationary relocations
0Working satellites 36,000 km up that left their slot or stopped at a new one, from their daily positions. One stopping beside another country's satellite is named.
None moved or arrived on this day.
Clusters over conflict zones in the next 24 hours
134 or more of one country's working military satellites, from different launches, over places where fighting was recorded this year, at once. Passes are fixed by orbits days ahead, so a cluster is usually a coincidence.
and 7 more
Military satellites whose public tracking stopped
0Working satellites whose public orbit updates stopped, or that left the public catalogue.
None on this day.
Possible breakups
0Three or more new pieces catalogued from a launch over a month old, in a week (Space-Track satellite catalogue).
None on this day.
Newly catalogued objects
0Objects that appeared in the public catalogue for the first time. One from an earlier launch can mean a satellite released something.
None on this day.
Launches
2On the day, then the next 24 hours.
Re-entries
0None on the day or predicted in the next 24 hours.
Built 20 Oct, 01:31 UTC from the event log: what overhead24 detected that day, in its own words. Sources: Space-Track.org (USSPACECOM) (orbit data and re-entries); GCAT (J. McDowell, planet4589.org/space/gcat) (owners and military class, CC BY 4.0); Launch Library 2 (The Space Devs) (launches); UCDP (where fighting was recorded, CC BY 4.0). Worked out from public orbit data, accurate to a few kilometres and less the older the data. Not for collision avoidance, navigation or targeting. Satellites pass over every country: being overhead says nothing about what a satellite is doing.
