A large, burning object seen breaking up over the Prairie provinces Friday night was likely a rocket booster re-entering Earth’s atmosphere after taking supplies to the International Space Station.

People in Saskatchewan and Alberta witnessed a bright light streaking across the sky, with what appeared to be parts breaking up and burning as it fell.

The object was visible across a large swath of Saskatchewan and Alberta, with sightings in Regina, North Battleford, Gravelbourg, Pierceland, Clavet, Zehner and Punnichy, Sask., as well as Medicine Hat, and Seven Persons, Alta.

The event baffled witnesses, who guessed it could have been a plane burning up or a meteor.
