Measurements of the night sky brightness at the Catania Astrophysical Observatory
Abstract
We report on measurements of the night sky brightness at the "M. G. Fracastoro" stellar station of the Catania Astrophysical Observatory during 3 moonless nights in February 1998. Measurements were performed in the broad band UBV filters. We compare our observed night sky zenith brightness to measurements from other sites and we also discuss the long term variations from 1980 up to now. Futhermore, we try to correlate the brightness variations both with the solar activity and with the mount Etna volcanic activity.
