Dynamic spectra of pulsation events at L of about 1.9 and L of about 3.3
Abstract
High resolution dynamic spectra of 12 pulsation events are compared at Nagycenk (L of about 1.9) and Evistaberg (L of about 3.3), lying on the same meridian. Common features of the pulsation activity at the two stations include periods, period shifts, and switches on and off. These parameters are investigated for the sample of pulsation activity and demonstrate that the two stations record activity from both a common and from different sources. Shell resonances are discussed in relation to the common source of activity.
