Reports Report 351a (Event 351-2011)

Observer
Name Shirley R
Experience Level 3/5
Remarks I have observed many meteors before and this was by far the largest and most spectacular for its color, duration and the fact that it was so large i'm sure some material must have survived impact. Holding my thumb out at arms length, it was bigger than my thumb! It had a dark core, ovoid, and was completely surrounded by a bright blue aura tapering rearward like a giant teardrop. It was lighter in color the further from the core and had a bright white aura in the tail around the edges. I did not see any pieces break off before it hit. It didn't get much smaller before it hit either, unlike most meteors I've seen. My best guess for impact is 15-25km north of Canadian Natural Resources Horizon Project. Best i can do without looking at a better map and triangulating where I was and which direction I was facing. Other workers in the area were saying on the radio "was that a flare?" but no-one really had the view I did. Please let me know anything!
