The Charlottetown meteorite was a meteorite fall observed on July 25, 2024. It is notable as the only meteorite known with video and audio of the impact recorded, and as the only known meteorite fall in Prince Edward Island.[2]
The Charlottetown meteorite is classified as H5 ordinary chondrite.[1]
Impact
After coming home from an evening walk in Marshfield neighborhood of Charlottetown, Prince Edward Island, Laura Kelly and her partner Joe Velaidum found a starburst pattern of gray dust on their sidewalk. They cleared it away, not knowing what it was. Upon discovering home security camera footage of the impact, they suspected it was a meteorite.[1] They contacted researchers, connecting with Chris Herd of the University of Alberta Meteorite Collection, and collected material from the impact.[3]
The recorded sound of the impact has been described as similar to breaking ice.[2] It caused a divot in the walkway approximately 2 centimeters in diameter.[1] Velaidum reports that he was standing at that location minutes before the meteorite struck it; he considers the event "a near-death experience".[4]
The meteorite came from the asteroid belt, according to the University of Alberta researcher, and would have traveled at least 200 kilometres per hour (124 mph) just prior to impact.[4][2]
Composition
Recovered fragments of the meteorite, ranging from less than one millimetre (0.039 in) up to seven millimetres (0.28 in) across, are made up of very fine grained, mostly translucent crystals. Within this are larger, translucent white and gray crystals and metallic fragments.[1]
