My nest camera has a updated lens for night vision, for low light. i have capture all moving objects in the sky, to include the x-37b in the morning. on oct 8 2019 at 0209, 2 object appeared on my video and what appeared to be in a battle with each other. only one will emanated a pulse of light, while the other looks like a beam. you can see the where the symbol nest is on the screen, this is not the first time on video but the first time i see 2 at the time. i do have a video of the x-37b for comparison. always comes over at the same time.
