The frequency of fireballs in our planet’s skies seemed to grow in recent months. NASA and other meteor experts can’t agree on what explains it.

In response to growing public interest, a NASA public affairs official said in a blog post at the end of March, “While it may seem like meteor reports and sightings have been more frequent recently, it is not out of the ordinary.” The post explained that from February to April, there is often a 10 to 30 percent increase in the number of extremely luminous meteors — and nobody is quite sure why.
Mr. Hankey said that this 10 to 30 percent increase was already baked into the American Meteor Society tally, and that it doesn’t explain the apparent doubling of fireball sightings in the year’s first quarter.
