A ‘fireball’ meteor - that’s what NASA says thousands of people in parts of B.C. and Washington state witnessed on Tuesday evening. Experts say a meteor travelling through the earth’s atmosphere was responsible for the bright light and loud booms heard in many parts of the Lower Mainland including Coquitlam, Burnaby, Port Moody, Delta, Surrey and Langley. The meteor was likely no larger than a softball when it streaked across the sky, at about 9:10 p.m.
