Phi Puma

Phi Puma was a star which was located somewhere in the Alpha or Beta Quadrant. Prior to 2165, this star went supernova which formed a concussion ring with a diameter of least ninety light years. In 2165, this ring reached Bayard's Planet.

In 2364, the location of Phi Puma was labeled in a star chart depicting the concusssion ring expansion. This chart was stored in the USS Enterprise-D library computer. Later that year, the chart was scanned by Outpost 63. (TNG: "The Naked Now", production art; TNG: "The Last Outpost")

This star was only mentioned in writing.
This star chart was drawn by Rick Sternbach for the Star Trek Spaceflight Chronology in the late 1970s. This chart was found on page 151.
In the Bayer designation, which was a system of stellar classification, the Greek letter indicated the brightness of a star in a constellation. In this case, Phi Puma would be the 21st brightest star in its constellation.
