I was lying on st. pete beach on a lounge chair, my head was facing the sky. i noticed three fairly bright lights in the sky, in a triangle formation, alternately flashing on and off. the three lights were fairly far apart, from where i was i could not tell how far apart, could have been 1000 feet apart, or more, or less, they were fairly high in the sky. at first thought it was birds, or an airplane, but they just hovered stationary in the sky. after about twenty minutes they appeared to climb higher in the sky, continuing to alternately flash on and off one at a time. the climbed higher and higher, rather slowly until they were all out of sight. my daughter allison was with me and observed the same thing.
