I’m sitting at the beach right now, and dead center above me, a white dot appeared. It’s mostly stationary, occasionally moving back and forth, apparently along the same line. It’s either distant or small enough to look point-like, and I can’t tell if it’s lit itself, or just reflects the sunlight (at first, I thought it emitted light, but now I don’t think so).
It’s been joined by two other dots, showing much the same behavior.
Best guess, right now: either high-flying seagulls (or another bird), or maybe balloons of some kind, perhaps from some celebration or another.
They’ve disappeared in the meantime; I haven’t seen them move away, they were just gone when I looked up just now.
Anyone got another guess?
