When I was living in California I had a pretty fun experience on 10-18-19. I was leaving Joshua Tree and heading to Redlands on I-10 to visit my then-girlfriend. It was a Friday afternoon at almost rush hour, so traffic was slow-moving. The drive between those locations is pretty boring and the turbines make it somewhat uncomfortable on account of the crosswinds, so my alertness was maybe heightened a bit. It is worth mentioning that this is very close to Twentynine Palms, which is one of the bigger military training bases.
I started to notice what looked like solid metal circles in the sky as I was driving. They were stationary and pretty unremarkable until the one I was observing just disappeared. It was how it disappeared that caught my attention. I had assumed they were stars or something, but I'd never seen a star vanish like a curtain was closing over it. It was like a weird mini-eclipse. I don't really know how else to describe it. Then it reappeared only in a completely different and very distant point in the sky. Same metallic-looking ball shape, but it looked brighter and then kept getting brighter until it also disappeared in the same manner as the first. By this point, I was compelled enough to pull over. I gave it a solid 10 minutes of entirely uneventful sky-watching before getting back in the truck and continuing into the slow trek.
Almost immediately it appeared again, but the entire process of appearing and then brightening and disappearing was happening faster now and every time it would reappear in some place in the sky nowhere near the previous. I wasn't going to pull over again, but the traffic was slow enough that I could reasonably grab my phone and try to snap off a couple of pictures before moving again. I took about 6 pictures out of my front windshield, but it was impossible to really watch where I was pointing it or what I was even aiming at.
By the time I arrived, I couldn't wait to look at the pictures to see if I could make anything out. Only one picture captured what I was seeing but I'll attach them all so you can all make fun of me properly.
I'm almost positive that it's absolutely nothing, but it was a fun time.
