UFO Sighting in Jacksonville Beach, Florida on March 21st 2016 – light flashing sequentially incl green, pink/red and 1 or 2 others. Hovered silently.

Near beach, walking dogs. Looking at stars and noticed flashing lights, bigger than jupiter. I thought airplane because I was in disbelief then thought it might be helicopter because it hovered but it was silent and helicopters aren't big spherical lights that change colors like this. I looked away for a few seconds to tend to dogs and when I turned back it wasnt visible anymore. A small plan did fly by shortly after with some alternating lights on bottom but it definitely was not same craft.
