But there have been some remarkable exceptions. In 1982 the rate unexpectedly reached 90 for a single hour, and 180 to 300 for a few minutes. A brief outburst of 100 per hour was also seen in 1922. And on April 20, 1803, residents of Richmond, Virginia, upon being rousted out of bed by a fire bell, were startled to see great numbers of meteors in all parts of the sky. "This unpredictability always makes the Lyrids a shower to watch, since we cannot say when the next unusual return may occur," note Alistair McBeath and Rainer Arlt of the International Meteor Organization.
