This article describes a fuzzy logic-based method optimized for the dome control of robotic astronomical observatory. A Mamdani inference has been developed in order to make decision open or close dome. The input variables are obtained from data received weather station besides percentage cloudy sky as derived by two allsky cameras. software tested at BOOTES-1 observatory part BOOTES Global Net...

Annotation Modern astronomy undergoes a big change due to a new possibilities enabled by technology development. Large scale survey projects produce huge amount of data, which needs to be processed and organized in databases to provide access by astronomical community. There are many problems in the current state of art of accessing large astronomical databases and organizing programmatic acces...
