Bright blue light near Jupiter, appeared and disappeared in a matter of seconds.

I was outside walking my dogs and looked up at the south eastern sky around Jupiter, there was a bright blue light (the same color blue as the lights from a police car).  It was about 5 inches to the right of Jupiter.  It was dim and got really bright and then just blinked out in just a matter of a few seconds. It is a cloudless night and the moon is not visible.
I was the only person that I know that observed it because I was walking my dogs, my dogs acted as if they were scared because they all came in within a minute of the sighting which is unusual for them.
I call myself a hobbiest astronomer, I do know where some things in the are in the sky.  I normally have my cell phone with me but tonight I forgot it in the house before I walked my dogs.
