Description
Since 2019 a set of three scintillator-based small muon telescopes of the Extreme Energy Events (EEE) Project have been successfully installed and operated at the high latitude (79° N) site of Ny-Ȧlesund, in the Svalbard archipelago. Such detectors have been employed for various analysis, also including the observation of Forbush decrease events in regions characterized by a low geomagnetic cutoff. The distances among the detectors range from 700 m to about 1100 m, also permitting the observation of coincidence events arising from the detection of extensive air showers. Muon rates from the three detectors were constantly collected, together with environmental parameters. Data were first saved locally and then transferred to the CNAF computing centre in Italy, allowing remote monitoring and analysis. The dataset originating from the last six years has been recently analyzed for a study of the periodical components in the measured muon rates. Various time-series algorithms and the Lomb-Scargle periodograms have been employed in this analysis, whose results will be presented and discussed in this contribution.
