(156990) Claerbout Main-belt Asteroid
Discovered on 28 May 2003 by J. Dellinger at Needville.
Jon Claerbout (b. 1938) is a prolific contributor to the theory and art of exploration seismology. He was the first to demonstrate a practical method for imaging the Earth's interior using wavefields modeled in a computer. He also pioneered seismic interferometry, a method now used to probe the sun.Naming citation (20110517/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
