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 a typical small scale K₂ᵥ emission feature is given.
