Stargazers were treated to quite the show on Friday night with a giant fireball spotted in Chatham-Kent.
Peter Brown, Western University professor in the astronomy and physics department, posted on Twitter on Saturday morning that the fireball ended at approximately 30 km in height just north of Lake St. Clair near Fair Haven, Mich.

According to the NASA website, observers in Ontario, Michigan, New York, Ohio and Pennsylvania reported the sighting at 10:07 p.m. EST.
“This event was captured by several all sky meteor cameras belonging to the NASA All Sky Fireball Network and the Southern Ontario Meteor Network operated by Western University,” it stated.
“A first analysis of the video data shows that the meteor appeared 90 km (56 miles) above Erieau on the northern shore of Lake Erie. It moved northwest at a speed of 105,800 kilometres per hour (65,800 miles per hour), crossing the U.S./Canada border before ablating 32 kilometres (20 miles) above Fair Haven, Mich.”
NASA stated the orbit of the object is “low inclination” and has an aphelion — defined as the point in the orbit of an object where it is farthest from the sun — near the orbit of Jupiter, and a perihelion — nearest to the sun — between the orbits of Mercury and Venus.
“It suggests that the meteor was caused by a fragment of a Jupiter family comet, though an asteroidal origin is also possible. At its brightest, the fireball rivalled the quarter moon in intensity. Combining this with the speed gives the fragment a mass of at least two kilograms and a diameter of approximately 12 centimetres (five inches).
