South Florida Sighting

Hello Martin…Finally, my first UFO sighting. I was in the pool this afternoon (tough life) and looked up to see a bright white object moving across the sky heading in a North-Easterly direction. The object was certainly weird, hence my ‘unidentified’ classification.
It was cylindrical, but traveling in a vertical/upright position, not in your normal aircraft horizontal mode. There seemed to be a circular halo around it and the thing also seemed to pulse as it moved across the sky. The speed did not not appear to be particularly fast, maybe 200mph. With nothing in the sky for comparison, altitude and size of the object is really a guess. There was no sound.
We do see a lot of aircraft in the area going into West Palm Beach airport. I’m sure this was not a plane and the flight path was not in the usual trajectory for West Palm. Couple of other points, time was just before 4pm, the sky was fairly clear with only a few clouds.
My first thought, I kid you not, was I have tell Martin. This is a world exclusive.
I have no idea what the protocol is or who to talk to
