I was walking my dog around the block when i noticed a bright star hanging low in the night sky. i watched it for a few moments and saw it begin to move slowly, and then vanish behind a cloud. i rushed around the corner to try to spot it again. it moved again behind the corner of a building, but i reasoned it was probably the cloud that was moving. halfway up my street i saw it hovering again a little farther north, between whyte ave and the river valley. it started flying east to west, back and forth for a few minutes, sometimes ascending quite high. it emitted light that changed color, entirely, from white to red, back to white, then to green, then to white, rotating like that at random. it started flying farther east and i had to move to keep tracking it my camera. then i heard a helicopter coming from the south east. it was a few minutes before i could see it. helicopter was white was red lights. i tuned off the camera when i couldn't see the object anymore (and my arms got too tired) but it was still on the footage. (**when i magnified the video at home it didn't look like there was any particular external light source other than the object itself. every frame captured an erratic micromovement, including rotation) youtube - ufo over whyte ave, edmonton, alberta - october 25, 2018 at 10 pm https://youtu.Be/icuzpu29mji
