After a three-year restoration and renovation, James Turrell’s Meeting re-opened at MoMA PS1 just last Saturday, October 8. The oculus, carved out of the ceiling, was originally commissioned in 1976, completed in 1980, and modified through 1986, ultimately becoming a prototype for a series of what the artist calls ‘Skyscapes,’ which invite viewers to gaze up at an unobstructed view of the sky.

The re-opening at MoMA PS1 will feature a modulated lighting program at sunset, utilizing LED lights that gradually brighten and dim to contrast the sky in transition. The LED fixtures, common in Turrell’s more recent works, are controlled by a computer program that automatically aligns the sequence to the setting of the sun as it shifts throughout the year. He has also maintained the original tungsten bulbs for its stark yellow tones, according to a press release from MoMA PS1.

The Museum of Modern Art acquired Meeting as a gift from Mark and Lauren Booth, who provided major support for the ongoing restoration and renovation processes in honor of the 40th anniversary of MoMA PS1. Turrell was involved intimately in the project’s revival, which included the repair of weather-related deterioration and components of a mechanical roof that covers the work when it is not open for viewing. Turrell also designed more durable teak wood seating to replace the original plywood, according to The New York Times.

MoMA PS1 will be hosting a series of twenty after-hours sunset viewings for Meeting which require a free advanced ticket through November 5, 2015. Beginning on November 6, the program will fall within regular museum hours.
