Chromospheric rotation

Solar Physics, 1979
In this paper the dependance of the rotation rate of chromospheric features on their is discussed. The angular velocity of short lived emission features at chromospheric level has been determined by analyzing daily filtergrams in the Ca 11K3 line, obtained at the Anacapri Observatory, in the period 8 May-14August 1972.

Diffusive fractionation in the chromosphere

Space Science Reviews, 1994
A new mechanism for the FIP fractionation in the solar wind in the form of a stationary diffusion model is proposed. It is based on a weakly stratified chromospheric layer of constant density and temperature, permeated everywhere by ionizing photons and a homogeneous magnetic field. Our model does not invoke any particular geometry or special set up of

The Dynamics of Chromospheric Spicules

Space Science Reviews, 1994
We present the observational results on chromospheric spicules obtained at the Sayan observatory 50 cm coronograph. To investigate the evolution of chromospheric spicules, we analysed spicule spectra of strong chromospheric lines measured simultaneously at three altitudes above the solar limb during 5–60 min with a time resolution of 10 to 20 s.

Chromospheric flares or chromospheric aurorae?

Space Science Reviews, 1975
This paper discusses some of the well-documented flare phenomena and possible analogies with magnetospheric substorm phenomena. Such analogies do exist, but also important differences. The combination of forces from magnetospheric and solar physicists will bring us closer to the understanding of these nearby examples of unstable cosmic plasmas.
