We've received a bunch of phone calls Monday about a ball of fire in the sky.

John Haley says that's exactly what it looked like.

"It was like a fireball falling right out of the sky," Haley told News 4 WOAI. "It was so bright! It was like a little piece of the sun falling with a big torch behind it."

I spoke to our astronomer expert Bob Kelley with the Scobee Planetarium, and he explained that it was a phenomenon called "April Fireballs."

Chunks of meteors enter and burn up in our atmosphere. The fireballs are brighter than a shooting star and can happen at any time of the day. For reasons astronomers don't fully understand, they occur in early April.

San Antonians weren't the only ones who saw the April Fireball Monday morning. Sightings were reported in New Braunfels, Kerrville, Floresville and other cities nearby.

"I can chalk that up on the old bucket list -- I saw a meteorite during the day," laughed Haley."
