Baltic Monitor (balticmonitor.eu) is a daily board of what is reported around NATO's north-eastern flank: Estonia, Latvia, Lithuania, Finland, north-west Russia, Belarus and the Gulf of Finland. Reports and rumours are listed as they arrive, with how sure they are and who said what first; machine measurements set the level; the map shows where. Free, non-commercial, no tracking cookies, no advice.
The About page has how to read the board, how it decides, its limits and its privacy terms: balticmonitor.eu/about. The sources and their licences are under Credits in the header.
The level is QUIET, WATCH or ELEVATED; there is no higher word. A report is reported (one source), corroborated (independent sources agree), confirmed (an official source), denied, debunked or cleared (confirmed harmless). Severity 1 to 5 says how bad it would be if true, by fixed rules. A source is described in words: official, a wire agency, a newsroom, a Telegram channel, state media; one marked "not used to confirm" is shown and counted, never used to confirm.
A circle with a pictogram is an incident (colour the severity, solid confirmed, hollow not yet); a pictogram alone in grey is history; a square is a place (port, airport, airbase, crossing, plant); a plain dot a sensor reading; a diamond a developing story. Airports and airbases show from zoom 6, the other places from zoom 7. Reports of the same incident are one event; a cleared or debunked report becomes a small grey check and leaves the map within about 13 hours. Developing stories are ordered by their newest report; a dimmed card marked "republished, first published ..." is an old article an aggregator served again.
Blind is not quiet: the volunteer ADS-B receivers barely reach Russia and Belarus, AIS does not reach the Kaliningrad coast or the port of Riga, Russian and Belarusian NOTAMs are not public, and satellites see effects, not causes. The full list is on the About page.
