Most recurring signals, if they recur at all, follow something in motion: the rotation of the earth, the passage of a satellite, the turning of the sky. FA-0902 does not. Its returns, logged over eleven years, correlate with fixed dates, and with nothing the Laboratories can find in the heavens.
The Laboratories have no mechanism to offer for a signal that keeps a human calendar. They record that it does, that the correlation is stronger than chance, and that it remains under study because the simpler explanations have failed.
What the public record includes
Modern recurrence file opened
Older station notes are consolidated into a ground-coupled review file.
Calendar correlation noted
Analysts identify stronger date alignment than sidereal or seasonal alignment.
Instrument-lineage review
Calibration breaks are reviewed and the recurrence remains in the retained record.
Public model release
Released as a behavioral record with station positions suppressed.
Review method
- Date-aligned recurrence testing with downtime removed.
- Ground-coupled vibration rejection.
- Comparison against lunar, solar, sidereal, and orbital period families.
- Station-maintenance and access-road ledger comparison.
Ordinary sources checked
- facility pump cycle
- scheduled maintenance
- road or gate activity
- sidereal period match
- Station positions are not public.
- The model is a correlation record, not a mechanism.
- Future returns require two-person public release review.
