I was standing in the back yard looking eastward at a very large firework show going off in the evening sky. after one particularly large explosion, i suddenly noticed out of the corner of my eye to the left, a glowing orb that seemed to blink and wobble. it appeared. it was not there when i first went outside. it stayed in one position for a minute or so, then it faded out. i then saw three show up in the same vicinity and they all glowed and wobbled and then faded out. for about 40 minutes or so, i saw them reposition in the sky and then fade out. these orb like things did move away in a horizontal and upward direction at times.

at one point, there were five or so and they seemed to be holding positions and observing the light show in the valley.

the objects spun or rotated so that their glow was inconsistent and it seemed that they had a dark spot on the side that spun around the object. also, the objects weren't true spheres. it seemed they were slightly diamond, like fat diamond forms. maybe soft cube forms as far as the glow area that was visible.

i wasn't sure what they were and at first i really thought they were helicopters or drones but there was no sound from these objects and they did not go downward when they disappeared or faded out. they appeared to morph shape.

eventually, they did not show up after a while.
