UFO Sighting in Denham Springs, Louisiana on March 14th 2016 – Very fast did not look like tech we use on earth

I was on my drive way looking due south and over the trees at stars and a half moon directly overhead I suddenly noticed a very small even tiny light white maybe slightly blue very high I am sure in space it went from exactly south to north in less than 20 seconds very fast never deviated or changed color none whatever it was went from horizon to horizon in 10 seconds had the kind of blue white color you see only from a fine time peace like a boron glow I just don't think our space machines go that fast maybe I am wrong but I have never seen anything like it before so I am hoping someone else has seen it
