Abstract:
Intensities at various wavelengths in the Ca II K line over a 10 minute duration time series spectra have been examined for oscillations. Three components have been observed:1) large period, ≥ 1000 second, due to the slowly evolving coarse network:2) 300 second resonant oscillations:and 3) the 180 second transient recurrent phenomenon. Life history of typical small scale K 2v emission features is given.
