Bright flash,large very bright star looking light hovering then quickly vanishing straight up and fading completely within half a seconI was driving south on Hwy. 11 at 3:27 am about 10 km north of New Liskard, Ontario, when a sudden flash of light almost like a camera flash came from the sky when I looked up through the top part of the windshield I noticed a light that looked like a star only 4 or 5 times bigger and 10 or 20 times brighter it stayed in the same spot for about 20 or 30 seconds and the excellerated almost straight up and got smaller and dimmer and completely disappeared within about half to a full second. The Sirius radio had also lost its signal during the time that the light was visible.
