static disk floating up and down emitting a redish hue from the top.

I was taking a nightly walk through an empty construction yard right next to my house to help clear my mind before i head in for the night when i saw this massive disk floating above one of the partially completed houses. It wasn’t moving too much, just floating up and down and at first i thought it was just a weird satellite dish but when i got a better angle it was floating a bit above the houses. I got freaked out and booked it away back home and when i looked back it was still there, looking out my window now, however, I can’t see it anymore.
