What happened?

Ball lightning refers to reported luminous spherical phenomena associated with storms, with many observations but no universally accepted mechanism.

Why it still matters

Stable source set includes encyclopedia, reference, and research material; the case should emphasize witness reports and scientific explanation attempts.

Current read

The case has enough stable source material to inspect, while extraordinary interpretations remain provisional.

Why the signal is high

This case has multiple accessible sources, a durable visual record, recurring anniversary coverage, and a clear unresolved residue: the later light row is explainable, while the earlier formation accounts are harder to reconstruct cleanly.
