Recent Solar Observations in Hydrogen and Helium Light.
Abstract
Prominences as seen in X 5876 of helium are sometimes higher or more abundant at the higher levels than the same prominences seen in Ha. Suggestions are made for more detailed studies of chromospheric eruptions. The greatly widened hydrogen emission lines and the appearance of helium emission and absorption in the spectra of eruptions are discussed. Certain very bright, low-lying, relatively inactive prominences are identified as the limb counterparts of the bright eruptions on the disk
