Why it matters: A midsummer ring over the Nordics.

Safety: an annular eclipse never becomes safe to look at. The remaining ring of Sun is blinding through the entire event — ISO-certified filters for every second, no exceptions. Eye safety.

This page carries NASA catalogue facts only — no city timings yet. When this eclipse gets close enough to plan, it will get the same treatment as 2027 and 2028: local circumstances computed for the path cities with our validated engine, cloud climatology where a source exists, and honest dashes where one doesn't.
