Extremely fast moving blinking white light with whitish trail behind, not a plane, falling star or satellite.

I was looking at the clear night moonlit sky at around 11:30 pm when I saw a bright blinking light that was moving very rapidly across the southern sky at about a 45 degree angle from the horizon. It moved clear across the entire sky in a very quick time and left a trail of white behind it for a short distance. I see airplanes, planets, falling stars and satellite s but it was non of these things, it moved so so fast across se to Sw horizon to horizon.
