5034 Joeharrington           Discovered 1991 Aug. 7 by H. E. Holt at Palomar.
Named in honor of Joseph Harrington (b. 1967), planetary scientist at Cornell University. Harrington has worked extensively with atmospheric modeling, and his work on modeling the 1994 cometary impacts on Jupiter was featured on the cover of Nature. His work on waves in the atmospheres of the giant planets utilized computer "pipeline" programs to analyze data sets too large to manage by hand. Living by his belief in the way things should be, Harrington has actively promoted the sharing of data and data processing software/tools for the benefit of all. Name proposed by B. E. Clark. Citation written by A. Simon and S. Sullivan.
