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.

Reading these warnings

Missile firing
Missile tests or exercises, with the danger area and times during which missiles may be in flight or falling.
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.
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.

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.
