Description
The spectra of the PROBA2/LYRA data, similarly to every other solar time series, show predominant periodicities that can be of solar or of instrumental origin.
In this paper, after assessing the validity of the LYRA time series by cross-calibrating them to SDO/EVE, we compare the main periodicities characterizing the LYRA spectrum to the ones found in the sunspot number, in the 10.7 cm flux, in a X-ray flare index, and in the sunspot area evolution. We mainly focused on the 2010 to 2014 time-range, for which the LYRA data are available.
