It wasn't a satellite.

The U.S. Air Force Space Command, which tracks space movement over North America, said today there has not been a man-made object flying over the Edmonton and northern Alberta region since at least Tuesday.

So that rules out the possibility that a bright fireball seen over Edmonton in broad daylight was that kind of man-made object. A number of Edmontonians spotted a bright fireball low in the sky while driving northbound Wednesday shortly after 1 p.m.

Witnesses described the bright streak with a bit of a tail using a number of colours, including blue, white, green, pink and orange. It lasted a few second before disappearing.

Bruce McCurdy, an astronomer at the Telus World of Science, received a few calls about the object Wednesday, confirming that there was something in the sky.

When told it wasn't a man-made object, McCurdy said the fireball was probably "interplanetary debris" as he initially suspected.

Seeing a fireball during the day, McCurdy said, is very rare occurrence.
