Join URBAN-15's annual celebration of the Summer Solstice at the San Antonio International Airport! The performance, choreographed and performed by URBAN-15 Artistic Director Catherine Cisneros, celebrates the longest day of the year under artist Christopher Janney’s solar/sound sculpture “Passing Light”. This transparent multi-colored plexiglass installation is designed to cast stunning colored shadows into the Parking Nave at the airport. Once a year, at 2pm Central Time, on the Summer Solstice, this multi-colored shadow grid pattern aligns perfectly with black-line grid painted on the floor for less than a minute as the Sun passes directly overhead. The audio aspect of the installation is a 56-speaker "spatial sound" composition. It consists of long harmonic, mellifluous tones (harp, vibe, acoustic guitar) reverberating off of the hard concrete surfaces of the garage, similar in effect to music in a stone cathedral. This performance will be free to watch live in person, as well as via livestream at URBAN-15's Facebook, and Instagram Pages.

Cisneros’ choreography incorporates the changing colors penetrating the environment. Her movements are designed to bring a ceremonial awareness of our planet's humble travels within a celestial clock, evoking the elaborate rituals performed by the ancient Egyptians, Aztecs, Celts, Mayans, Hindis, Incas and others to make visible the moment of solar zenith.

The Summer Solstice is the longest day of the year, respectively, in the sense that the length of time elapsed between sunrise and sunset on this day is a maximum for the year. In the Northern Hemisphere, the longest day of the year (near June 20/22) is when the Sun is farthest North. In the Southern Hemisphere, winter and summer solstices are exchanged. The Summer Solstice marks the first day of the season of summer.
