Optical Flash From GRB 130427A

November 21, 2013

This movie shows GRB 130427A as viewed by the RAPTOR telescopes located near Los Alamos, N.M, and on Mount Haleakala on the island of Maui, Hawaii. The movie opens with wide-field images acquired by a RAPTOR All-Sky Monitor, one of the three identical systems to first detect the burst’s optical flash. The movie then switches to observations from RAPTOR-T, which autonomously turned toward the burst after receiving an alert from NASA’s Swift. The telescope imaged the burst for 2 hours and captured simultaneous images in four different colors.
