We investigate the distribution of fluctuations in solar irradiance when integrated over the full disk, obtained using extreme ultraviolet / soft X-ray observations from the SOHO CELIAS / SEM instrument. This time series sums over both the contributions of single distinguishable flares, and of many other processes. By detrending we select events wi…

Quasi-periodic EUV disturbances simultaneously observed in 171 Å and 195 Å TRACE bandpasses propagating outwardly in a fan-like magnetic structure of a coronal active region are analysed. Time series of disturbances observed in the different bandpasses have a relatively high correlation coefficient (up to about 0.7). The correlation has a tendenc…
