Observer
NameBruce M
Experience Level4/5
RemarksAs a meteor observer of long standing, this was one of the very brightest I've ever seen. Not #1, that would be the Buzzard Coulee meteorite fall in 2008 which was close to mag -20, but this was a spectacular flash lasting an estimated 3-4 seconds. Observed by myself, another volunteer & several visitors here at the RASC Observatory at Telus World of Science, Edmonton.
