Magnetometer array reports deviation from baseline. Deviation: [REDACTED]. This reading last recorded: [REDACTED].
Warden notified. Status elevated to ELEVATED pending full analysis. Archive cross-reference query submitted for prior instances of correlated polar deviation.
The archive cross-reference query returned four prior instances. The dates of those instances are published here: 1859, 1882, 1938, 1989. The characteristics of each prior instance are restricted at degrees corresponding to their sensitivity. The Institution notes that the intervals between instances are not regular and that no predictive pattern has been established.
