Measurements of 1-Hz Coronal Oscillations at Total Eclipses and Their Implications for Coronal Heating

  • Jay M. Pasachoff


As a test of predictions of solar coronal heating via surface Alfvén waves, we observed small coronal loops during the total solar eclipses of 1980 and 1983. Our results indicate excess power in the 0.5–2 Hz range at the level of 1% in the coronal green line relative to continuum oscillation power. The results indicate that the surface Alfvén-wave models of Ionson and the subsequent Alfvénic models of Hollweg can supply adequate energy to heat the corona.
