Penn will be investigating the solar He I 1083 nm line to measure
velocities and magnetic fields in the upper solar chromosphere. He
will work with Harvey and Jones to take science data with the new KP
Helium Filtergraph/Magnetograph. These data, along with spectral
observations of the line, will be used in conjunction with data from
the SoHO satellite to study the line formation and the dynamics of the
solar atmosphere (with Jones and Andretta (NASA)). Penn is involved in
two coronal joint-observing programs with Mason and Young from
Cambridge. SoHO observations from Mason and Young will be combined
with NSO observations from Penn to study the electron density in the
solar corona, and to investigate temperature changes in active solar
coronal loops. Finally, with Kuhn, analysis of 1994 eclipse data will
progress, and plans for future eclipse observations will be made.
Penn serves as an observer at the KPVT, collecting synoptic magnetic and He I 1083 nm observations 6-7 days per month. He is also a liason between SoHO scientists at NASA/GSFC and NSO.
