(23884) Karenharvey Main-belt Asteroid
Discovered on 20 September 1998 by R. A. Tucker at Goodricke-Pigott.
Karen Lorraine Harvey (b. 1942) has investigated extensively the relationship of solar magnetic fields to coronal heating, x-ray emission, large active regions, ephemeral active regions and the solar cycle. Her work has provided fundamental statistical data on the nature and evolution of the solar magnetic field.Naming citation (20020128/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
