Pulsating UFO Sighting in Alaska

Summary

A civilian observer in Alaska described a star-shaped object pulsating in red, green, and white colors in December 1960. The object appeared and disappeared multiple times over 45 minutes, moving up and down, side to side, and in slow circles before returning to its original position. The cold and clear atmosphere may have influenced the perception of the object's unusual movements. The observer did not immediately recognize it as the bright star Arcturus, which was later suggested as a possible explanation.

The official report concluded the object was likely Arcturus, a bright star visible in the night sky. However, the pulsating colors and erratic movements initially caused confusion. Although no photos or radar data were available, the intelligence officer in charge noted that the behavior matched an astronomical observation. The case was archived without further investigation, but it remains a curious example of how natural phenomena can be misinterpreted as unexplained events.
