Deep Impact or Armageddon it certainly wasn’t. Not even close. But Asteroid 2014 did put on a nice little show for astronomers as it streaked through space toward its demise over the Atlantic Ocean on New Years Day.

That’s it in the animated GIF above — a chunk of rock about six to nine feet across zipping across the starry background. Asteroid 2014 AA was discovered by the NASA-sponsored Catalina Sky Survey, which operates near Tucson, Arizona. According to NASA, it entered our atmosphere late on Jan. 1 and likely broke up.

Based on the Catalina Sky Survey observations, a scientist with the Jet Propulsion Laboratory determined that the asteroid probably exploded in the atmosphere somewhere along the blue line in the map at right.  (Click on it for a larger version.) The red dot indicates the likeliest spot, determined by analysis of low frequency sounds detected by observation sites of the Comprehensive Nuclear-Test-Ban Treaty Organization.

Luckily, Bruce Willis was not needed to try to save the day. This time.

    If it was a practice shot, let’s have it a bit more to the east to avoid Panama and include Yemen. Bring on the 50-meter (re Tunguska) bolide!

    Perhaps the ’100 year event’ classification should be re-evaluated.
