At approximately 5 a.m. on Tuesday, March 18, a fireball filled the morning dark sky with light over Canada's Maritime provinces and areas of Quebec.

Accounts given by witnesses to Director David Lane of Saint Mary's University Burke-Gaffney Observatory in Halifax have led the astronomer to believe that it was an “extra-bright meteor.”

Lane stated to the press that although there's approximately 100 tons of materials that enters our planet's atmosphere daily, it's unlikely that a sizable rock or debris will be found because the potential impact areas are heavily wooded and near the ocean. Only one meteorite has ever been found in the Maritimes. The "Benton Meteorite" was found in Benton, New Brunswick in 1949.

Lane compared any search for potential fireball debris to the ongoing search for the missing Malaysia Airlines flight. He explained that astronomers would need additional information, including direct line-of-sight accounts of the fireball's path, to triangulate location.

Many witnesses heard rumbling and thunder-like sounds during the event. Some have told the press that it was like the sun falling or a piece of metal on fire. They also described seeing different colors, including yellow, red, green and blue.

Keswick Valley Fire Department Captain Dan Roy saw the fireball while travelling home in New Brunswick and described seeing “sparks and flames” before it disappeared.

Metal within the object or a metal "space junk" fragment could have caused the colors and heightened brightness upon descent. It's unknown whether the object was one of the tens of thousands of pieces floating above Earth or what factors beyond gravity prompted the object to be pulled from orbit into our atmosphere.

The International Space Station was also above the area at the time. It even had to be relocated on Sunday because of hazardous debris.
