As forecasters predicted, there was a surge of Leonid meteors during the late hours of Nov. 17th. Preliminary counts from the International Meteor Organization exceed 120 meteors per hour.
A remarkable midnight fireball that "turned night into day" over parts of the western United States last night was not a Leonid. Infrasound measurements suggest a sporadic asteroid not associated with the Leonid debris stream. The space rock exploded in the atmosphere with an energy equivalent to 0.5 - 1 kilotons of TNT.
Approximately 6 hours later, observers in Utah and Colorado witnessed a twisting iridescent-blue cloud in the dawn sky.
