South Atlantic · 2 notices · issued 2026-09-27 to 2026-09-27

What the reports establish

These reports were linked by category and sea, with positions within 30 nautical miles and issue dates within 30 days of another report's recorded in-force span. Links can extend through other members, so the full group can cover a larger area or period. Proximity does not confirm that they describe one incident.

What the numbers show

All 2 located notices give the same position (to about half a mile).

Together the notices were in force for 3.3 days; overlapping notices are counted once.

Reading these warnings

Hazardous operations
NGA's heading for activities that make an area dangerous — most often rocket launches, space debris and weapons firings, and some open-ended danger areas.
Space debris
An area where parts of a spacecraft or rocket stage are expected to come down at sea, from a launch or a planned re-entry.
Date-time group (DTG)
A compact UTC timestamp — day, hour and minute followed by Z — such as 201500Z for the 20th at 15:00 UTC.
Area bound by
Introduces a list of positions that are the corners of an area — the polygon the warning applies to.
Position (degrees and minutes)
How warnings write positions: degrees, a hyphen, then minutes, with N/S and E/W — 49-40.8N 003-43.8W.
CANCEL THIS MSG
The warning's own expiry: a line telling the reader when the message cancels itself.

All warning terms →

Representative geometry selected from a member warning when this group was assembled. It is not the full affected area or a track. Each linked notice retains its own reported location.

Report comparison · 2 notices

Each report is compared with an earlier notice it explicitly cancels, when available, or with the preceding report. Changes refer to recorded wording and parsed fields; quoted lines are textual differences, not a verified account of how an incident developed. Nearby reports can describe different hazards. A status explanation is given once, on the first notice with that status.
