Scientific paper

An analysis of solar semidiameter measurements obtained with the CERGA solar astrolabe for most of the 21st solar activity cycle reveals the presence of oscillations. Some of the oscillations are correlated with certain solar activity indices, with the neutrino flux, and with large-scale convection. Diurnal mean values of semidiameters were harmonically analyzed with a least-squares method. Several long period oscillations (50-1000 days) with amplitudes near 0.10 arcsec have been detected, and the results suggest a negative correlation between diameter measurements and the sunspot cycle.
