This unknown object was captured using the FREE UFO Detector software on 5/4/2015 over North Hollywood, California.
The UFO appears in the upper right corner. Yes, it is quick, but is anomalous compared to many captures of birds, planes, etc.
It appears quickly, then vanishes before it exits the frame. Most, if not all, planes or birds captured (which are generally ruled out anyway) stay visible, but may change with luminosity (brightness) or shape (due to direction change) but this stands out as different.
