CPCS 2.0 — new automatic tool for time-domain astronomy

The Cambridge Photometric Calibration Server (CPCS) has been designed to respond to the need of automated rapid photometric data calibration and dissemination for transient events, primarily from Gaia space mission. The Calibration Server has been in operation since 2013 and has been used to calibrate around 50 000 observations of hundreds of transients. We present the status of the tool and demonstrate improvements made in the newest version, which is enhanced with build-in profile photometric measurement. After tests and implementation on the dedicated website, the new Server will be able to combine imaging data from multiple telescopes and is intended to provide science-ready photometric data within minutes from observations. We also present the OPTICON-supported network of telescopes for Gaia alerts followup.
