John Heise (b. 1942), professor of general physics at Utrecht University, specialized in high-energy space physics. In 1975 he discovered and detected sources of galactic x-ray bursts (1975). He was among the discoverers in 1998 of the origin of the cosmic γ-ray bursts. The name was suggested by C. de Jager.Naming citation (20001111/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
