An organization called the UFO Global Reporting Center has posted a video on YouTube that purports to show triangles of light in the late afternoon sky over Zapote.
The source is unidentified, and the video is short. The sky appears to be green. The caption says there were seven glowing orbs in two triangles.
The lights seem to blink as if being covered and uncovered with clouds. The sky was overcast Friday afternoon, and rain was falling in San José for much of the afternoon.
