- The project reports 3,060 readings across 612 sessions at 28 fixed points in 11 towns and cities.
Field notes
Observations are made at fixed locations on clear nights around each new moon, using a pocket photometer held vertically. The site explains that repeated readings support comparisons across districts, seasons, and years, and includes monthly 2025 medians for two contrasting locations. Its updates also report session totals and local changes, including an account of the 2026 summer season.
