Alan Strauss at the Mount Lemmon Sky Center in Arizona says these spectacular fireballs are quite common.
However, Strauss says people often miss them because they just don't look up that much.
Canada: Halifax, Nova Scotia - Ball of Fire
The fiery object appeared to travel from west to east over the Halifax area at around 9:30pm.
Last night (Jan 31 - 11pm MST), I caught a bright orange one NE of my position in El Paso, TX as it lit up a few scattered clouds overhead. It came down nearly vertically and extremely fast from a sky region just below Leo - it broke into 3-4 pieces and even left a smoke trail. Was my third sighting in a year's time. These do happen quite a lot, but as Strauss says - it helps to always keep an eye out.
