I was stand on back porch and noticed bright white solid star like object appx 45 degrees in sky moving from west to south in front of me. i observed the object make a sudden but short lateral darting motion before object made sudden stop. after approximately 5 seconds object continued along lateral path toward my view of the moon which was behind light cloud cover. the object appeared to suddenly increase altitude and at this point i was aware of a second unlit ball/ cube shaped object following behind. it appeared to chase the illuminated object in a circular motion around my view of the moon. the illuminate object then dissapeared leaving only the unlit object in the sky, which also suddenly dissapeared a few seconds later. managed to take a sequence of photographs of the incident using a digital camera in night mode as i knew from seeing similar objects previously, that the image quality would be brighter than if filming. i also maged to stich the images together into a short video sequence.
