D. Rankin detected a fast moving object in images taken at Mt. Lemmon
Survey (G96). The observations triggered a warning of an imminent impact.
Seven observatories were able to observe the sub-meter object before it
impacted the Earth's atmosphere on Nov. 19 at approximately 08:27 UTC over
Brantford, Ontario, Canada.
