Scientific paper

An automated wavelet analysis approach to TRACE UV quiet Sun datasets is discussed. Periodicity and lifetime of oscillations present in the network and internetwork are compared and contrasted. This provides a means of extending previous Fourier results into the time-localised domain. The longest lifetime oscillations occur around the acoustic band and the network tends to dominate over the internetwork at periods 4 mins. However, it is shown that the internetwork can dominate over the network at long periods (7 - 20 mins), but only for short lifetimes ( 3 complete oscillations). These results are discussed in terms of chromospheric heating theories.
