The Occultation Portal (OP) is a scientific infrastructure originally developed within the ERC Lucky Star collaboration with groups from Paris, Meudon, Granada and Rio, and is now actively used in ongoing occultation-focused projects such as ACROSS and GaiaMoons. It supports the full workflow of stellar occultation studies, including prediction and campaign coordination, as well as the ingestion, validation, and long-term archiving of both video-based and photometric observations. With upcoming surveys such as LSST and future Gaia releases expected to significantly increase the number of observable events, ensuring the scalability and operational robustness of the OP has become essential.
Over the past six months, the Occultation Portal has been migrated to the PADC/DIO infrastructure of the Paris Observatory and has undergone a broad technical modernisation. This work includes the implementation of a full MD5-based data-integrity framework, GDPR-compliant handling of user and observatory information, a redesigned user-registration and moderation workflow, an upgraded publication system with ADS-powered metadata ingestion linking scientific outputs to OP events and archived data, and extended prediction and mapping tools. Together, these developments greatly enhance the platform’s long-term stability and ensure that the OP continues to serve as a reliable infrastructure for advancing stellar occultation science.
