Chromospheric dynamics based on infrared solar brightness variations
Author(s): Kopp, G.; Lindsey, C.; Roellig, T. L.; Werner, M. W.; Becklin, E. E.; Orrall, F. Q.; Jefferies, J. T.
Abstract: The NASA Kuiper Airborne Observatory was used to observe far-infrared continuum brightness fluctuations in the lower chromosphere due to solar 5 minute oscillations on the quiet sun. Brightness measurements made at 50, 100, ...
