Casually checking out my all-sky camera, I caught a strange phenomena.
Going outside it turned out to be a mesmirizing spiral that crossed the sky from NNW towards E in about 15 minutes, around 21 MET.
My son Warre Verheyden could capture it on the phone camera:



Most likely a Falcon 9 rocket stage with a fuel cloud spiral, generated by the tolling stage. The launch was 18.48 MET on Cape Canaveral SLC-40
