Astronomical observations

SERIES: Astronomical observations at the Astronomical Observatory of Bologna

52 notebooks from 1723 to 1844; originaly numbered from 1 to 12. From vol. 7 to vol. 12 there is a double series of numbers, referring to the"usage of the new english instruments".
From 1808 onwards each volume comprehends one year of observations, both astronomical and meteorological. From 1813 meteorological observations are listed separately. During the XIX century the Institution undergoes some changes in its name: Regio Osservatorio di Bologna in 1808, Specola di Bologna in 1817, Specola Pontificia di Bologna in 1819 and again Specola di Bologna in 1829.
