Although the object was very compact but much larger then a star, it was exceedingly bright (blue white) with a short tail. It moved across my field of view in about 15-20 seconds.

Remarks
as the main bright object traveled almost perfectly horizontally north to south I saw 2 or 3 small pieces come off which were temporarily as bright as the main object although they lasted for only 2-4 seconds.
