So it carries active_until: 2026 -- which is the field's real meaning, 'the sponsor stopped running it', and NOT the same state as the thirty-odd manual records waiting for next year's dates. The detail page will say the record is closed rather than missing, and it stays off the expiry cliff because there is nothing to re-check.\n\nIf RSGB runs an eclipse contest for a future eclipse it will be a different contest with different propagation to study, and it gets its own record.\n\nRAN ALONGSIDE THE CW ECLIPSE CONTEST, same three hours, different band: CW on 80 m and FT8 on 40 m. Two bands watched at once during the same eclipse is the point of running two.",
