At solar noon on the day of summer solstice, Solar Rotary's shadow caster casts a circle of light around the central seat. On five specific days of the year, at times specific for each day, Solar Rotary casts its circle of light around plaques placed in the ground plane of the plaza that mark historic events for the State of Florida and the city of Tampa. Additional seating is provided both around the perimeter of the plaza, and on four benches set into the nearby landscape marking the cardinal directions, North, South, East and West.

The large ring on the central circular seat is inscribed as

THE DAY OF THE SUMMER SOLSTICE AT SOLAR NOON BETWEEN 1:31 AND 1:32 PM A CIRCLE OF SUNLIGHT WILL BE CAST AROUND THIS CIRCULAR SEAT.

A circle of sunlight will also surround five 12 diameter bronze plates in the plaza pavement at specific times on certain historical dates inscribed on the plaques. These dates are:

On any sunny or even hazy day Solar Rotary will cast its dynamic sun symbol shadow in a continuously changing pattern on the pavement below. And every day circular shapes of sunlight will be cast around the plaza.
