Orb of light changed directions rapidly in the sky

This is the second time I have witnessed this type of activity early in the morning.  The first was at 4:45am with my fiancée and this was at 5:38 am. Alone.  I was walking my dogs and looked up into the sky because a bright orb caught my eye.  As I looked at it, it seemed to be about ¾ of a mile to a mile away. It moved up and then down and then back and diagonally very quickly and then stopped abruptly to hover.  As it hovered it was swinging slightly from right to left, then it crossed the sky towards the east very slowly emitting a white light.  No plane or helicopter I know of moves that way. The bright white light was moving slower than the first one I encountered in February that moved very very quickly across the sky in al directions.
