             abstract = "In this work a study of the effects of the highintensity 
                         long-duration continuous AE activity (HILDCAAs) events in the 
                         magnetotail was conducted. The aim of this study was to search the 
                         main frequencies during HILDCAAs in the Bx component of the 
                         geomagnetic field in the magnetotail, as well as the main 
                         frequencies, at which the magnetotail responds to the solar wind 
                         during these events. In order to conduct this analysis the wavelet 
                         transform was employed during nine HILDCAA events that coincided 
                         with Cluster spacecraft mission crossing through the tail of the 
                         magnetosphere from 2003 to 2007. The most energetic periods for 
                         each event were identified. It was found that 76 % of them have 
                         periods \≤ 4 h. With the aim to search the periods that 
                         have the highest correlation between the IMF Bz (OMNI) component 
                         and the Cluster Bx geomagnetic field component, the cross wavelet 
                         analysis technique was also used in this study. The majority of 
                         correlation periods between the Bz (IMF) and Bx component of the 
                         geomagnetic field observed also were \≤ 4 h, with 62.9 % of 
                         the periods. Thus the magnetotail responds stronger to IMF 
                         fluctuations during HILDCCAS at 24 h scales, which are typical 
                         substorm periods. The results obtained in this work show that 
                         these scales are the ones on which the coupling of energy is 
                         stronger, as well as the modulation of the magnetotail by the 
                         solar wind during HILDCAA events.",
