Night motion.
The library is closed from ten at night to six in the morning. If the radio links between our receivers change at the same minute on two receivers at once, something may have moved near them. This page lists every closed night the detector has judged, what it found, and how many such coincidences chance alone would give.

The site reads a copy built offline; no request reaches the database or the lake.
The ledger holds 54 nights, from 2026-08-31 to 2026-10-24. 18 quiet, 1 possible, 1 corroborated, and 34 insufficient, which means too few receivers had a floor to judge against. On the 20 judged nights the detector found 17 events; chance alone would give about 10.67. Receiver pairs: monad07+monad10 (17).
The calendar
One square per night, keyed by the date the night starts on. Pick a night to see its events below. A small number in the corner is that night's event count.

Events against chance
Each bar is one night's event count. The black tick is the same night's chance rate. A bar that does not clear its tick by a wide margin is a night chance explains.
Every night on one clock
Each row is one night from 22:00 to 06:00. A dark mark is one event at its time of night; a red mark is an event that Bluetooth activity coincided with.

The detector could not judge this night: too few receivers had a floor to compare against. That says nothing about whether the library was empty.
