This market tests the "Engine Cutoff" hypothesis. Natural comets are expected to fade gradually according to an inverse-square law (1/r^2) as they move away from the Sun. 

RESOLUTION CRITERIA:
Resolves YES if the Hydroxyl (OH) or water-vapor production rate exhibits a discontinuous, step-function drop from >30 kg/s to <3 kg/s within any 48-hour window between May 15 and May 30, 2026. Resolves NO if the object follows a standard, gradual decay curve without a sudden cutoff.
