UFO Sighting

I’m not saying it was an alien spacecraft, just that I don’t know what it was and it was flying.

Last night I was walking home from work around 8pm.  In my peripheral vision, I saw a light moving.  It was blueish white, not as bright as the street lights but much bigger than the visible stars and much bigger than airplane lights.  It was more like a glow than a beam of light.  The light appeared above the trees moving downward but might also have been moving away from me.  It moved too slowly to have been a meteorite.  One or two seconds after I turned to look at it, it seemed to shrink and disappear like a circle being turned on its edge or a closing eye.

All in all a rather tame sighting.
