Named in honor of Stephen J. Edberg, planetary scientist at the Jet Propulsion Laboratory, for his long commitment to bringing amateur and professional astronomers together. Although his most noted activity has been his work with the Amateur Observations Net of the International Halley Watch, he has also been a leader in the program for amateur use of the Hubble Space Telescope, in the Mars project of the Planetary Society, and as president of the Western Amateur Astronomers.
