Monday was Labor Day holiday in both the US and Canada, sending people outside to enjoy the final weeks of summer in the Northern Hemisphere. In parts of Canada and New York, the good times also came with a special sky show sent straight from space.
A spectacularly bright fireball was spotted across Alberta Saturday night, and the following evening folks in parts of Ontario and western New York saw a similar sight in daylight skies that was reportedly accompanied by a loud booming sound. Both events were likely the result of a meteor burning up as it streaked through our atmosphere, creating a sonic boom in the latter case on Sunday.
The Saturday night fireball was caught on the below dashboard camera outside Edmonton around 10:30 p.m. locally:
Over 175 people from Alberta reported seeing the fireball to the American Meteor Society.
Fewer people reported the New York fireball, which happened just after 5 p.m. ET on Labor Day, but it made an impression on those who caught it.
"This bright, fast streak in the late afternoon appeared against a brilliant blue sky and, after sparkling with a flash of rainbow colors, disappeared behind a fluffy white cloud," reported one eyewitness.
Others reported hearing the fireball but not seeing it, as accounts also circulated through the local media of a sudden, unexplained boom.
Meteors burn up in our atmosphere every day, and even create brilliant fireballs in the sky several times a month, on average. In most cases we're dealing with tiny bits of cosmic rock or dust that are completely consumed by the friction of colliding with our atmosphere. It's more rare for a, and almost unheard of for a space rock to do much damage when they do it.
In the famous case of the bomb that exploded over Russia in 2013, it was a house-sized asteroid that went undetected until its collision with our atmosphere sent shock waves that blew out thousands of windows.
Bottom line: fireballs should be more of a cause for wonder, but it's always a good idea to keep an eye on the sky.
