Discovered on 2 March 1981 by S. J. Bus at Siding Spring.
Elizabeth A. Jensen (b. 1975) is an American space scientist who developed a method of studying solar corona structure using the Faraday effect. She measures the solar magnetic field and studies the dynamics of coronal mass ejections and magnetohydrodynamic waves by analyzing radio signals from interplanetary spacecraft.Naming citation (WGSBN Bull. 3, #3, 10), IAU / Minor Planet Center, via NASA/JPL
