Observed bright white cylindrical UFO traveling in vertical upright mode (with slight tilt forward at top) versus horizontal as conventional aircraft. Watched object for about 1 minute as it ascended gradually in a North East direction just below cloud level into the clouds before disappearing from view. UFO Sighting appeared to be surrounded by a halo and also pulsated or phased in and out as it moved across the sky. This was just before 4:pm in the afternoon, 6-9-20 sky was fairly clear with some puffy clouds. I do not believe it generated any sound, but there was other local noise close by (truck idling). It was the unusual flying position (upright) that drew my attention. I have provided a photo taken the day after from the same viewing position. mufon cms# 109397 Royal Palm Beach Florida Region has had 5,602 Reported UFO Sightings to date.
