Skywatchers might get a bonus this Sunday, when a meteor storm not associated with a major meteor shower could light up the morning.
In the pre-dawn hours on May 15, our planet will pass through a field of debris left by a large asteroid known as 2006 GY2, which completes a single orbit around the sun every 925 days, and crosses Earth’s orbit in the process.
“This object is actually a double minor planet with the main body estimated at 400 meters (1,312 feet) and the secondary satellite at 80 meters (262 feet),” Robert Lunsford wrote for the American Meteor Society. “While the density of debris field is unknown, the fact that this object is a double minor planet may provide a dense stream of debris.”
As bits of dust and space rock collide with our atmosphere, they can burn up and create fleeting “shooting stars” or brighter-burning fireballs.

AMS isn’t making predictions about exactly how many meteors we might be able to see in the sky, but Lunsford notes the potential peak watching time is as close to 3:20 a.m. PT as possible.
“This timing is ideal for the southwestern USA and Mexico. Unfortunately the moon is only one day from full and any faint meteors will most likely be obscured by the intense moonlight,” Lunsford said.
If you’re able to get up before dawn Sunday to check it out, you’ll want to choose a viewing location as far from light pollution as possible with a broad view of the sky. Give yourself at least an hour for the whole viewing experience, including 15 to 20 minutes for your eyes to adjust.
Good luck, and let me know on Twitter what you see.
