Rolling review of recent NAVTEX notices, with emphasis on operational changes, weather warnings, navigation hazards, and signal integrity issues.

What this is

This page is a rolling 24-hour review of the latest NAVTEX corpus. The letter codes in the feed are NAVTEX B1 transmitter identifiers rather than plain-language sea areas, so the page keeps the raw code activity while also resolving likely source stations where the message text is clear enough to support it.

Older rebroadcast notices removed in this edition: 61.

  • No direct mentions were found in this corpus window.

Data Quality Notes

  • Decode quality across the window was high=53, medium=37, low=9.
  • 61 older rebroadcast notices were removed because their internal issue times predated the 24-hour operating window.
  • Published timestamps reflect reception time in the received corpus, not necessarily original notice issue time.
  • Repeated or rebroadcast notices can persist inside the rolling window; message IDs are retained for traceability.
  • 9 messages were classified as low decode quality and may contain damaged titles or coordinates.

Regional Focus

The standing watch region for this edition is Strait of Hormuz. Direct-hit count in the current window: 0.
