single orange fireball travelling across sky.At approximately 2:30 am, in Alberta, Canada, on the highway 16 corridor, between Vegreville and Vermilion, I witnessed what appeared to be an orange flame-looking object, traveling westbound and the object made no noise (appeared to be the size of if you look at a full moon at its highest point in the sky, you take that size and reduce it by a third) It appeared to be a little north of my position the distance traveled was at approximately 30-45 degree inclination it took about a minute to travel that distance.
