Bright white(snow white), slightly elongated object spotted hovering for a few seconds. it then appeared to accelerate incredibly fast leaving a short and brief bright white tail before completely disappearing. the entire sighting was only seconds long, maybe about 10. it was spotted a very early in the morning in the dark. the night sky was the only backdrop which made judging distance and size extremely difficult. i captured no photos of videos because of how quick the sighting was. i did however find a photo of a sighting in canmore, ab from 2016 that is exactly what i saw. only difference being that sighting was during daylight. the size from my perspective was roughly pea - aspirin size.
