In the Southern Hemisphere summer, the sun shines 24 hours a day in Antarctica.

This roughly 90-second video--which was shot with a 360-degree camera from the top of chemistry lab at the NSF-funded SALSA Antarctica (Subglacial Antarctic Lakes Scientific Access) project site--captures the sun making a circle of the sky, beginning at 10pm on December 20, 2018. The time-interval for the individual images was 15 seconds per picture.

The time-lapse was shot by Wei Li, a SALSA scientist with a background in microbial ecology and geomicrobiology. The soundtrack was created by SALSA Principal Investigator John Priscu. Both are at Montana State University.
