An extremely impressive fireball was seen over the Canadian provinces of Saskatchewan and Alberta on Thursday evening, November 20. Whether the fireball was due to a small asteroid or a piece of man-made space junk is not clear. The fact that no large pieces of space junk were known to have re-entered the Earth’s atmosphere at that time points to an asteroid being the culprit.
