Orbs appearing and disappearing nightly

[TheADHDChicken]

So I have been watching some orbs of light appear in groups of 1-9 at 4 am every night for about 14 months now. I went as far as spending $600 on a canon rebel T6 with a 300mm lense to capture these on film. I was forced to use 300-500 consecutive long exposure shots. Then I assembled them into a sort of slide show. So the object appear to be moving much slower in real time. Each frame accounting for about 2 seconds of real time. And my camera was facing east.

Camera settings:
2 second exposure time
ISO 800
Mid level brightness

If anyone can explain this phenomenon as normal I would greatly appreciate it.
