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.
