The whole story began when I (Y. Kilic) met my Ph.D. co-supervisor Dr. Felipe Braga-Ribas during the Summer School on Astrometry and Astrometry Now and in the Future held at TÜBİTAK National Observatory in Türkiye in 2011. Years later, as our collaboration grew stronger, we discussed how to make stellar occultation campaigns significantly more efficient. With his guidance and invaluable support, the idea that eventually became the Occultation Portal was born.

The stellar occultation technique is a unique and reliable method to investigate the size, shape, and environment around Solar System objects. One of the indispensables of this technique is multi-chord observations. Sometimes collecting observational data and equipment details from observers affects prolonged research time. For this reason, we aimed to create a common online platform where the needed data will be collected and analyzed (producing light curves/photometry) in a single center for ongoing campaign observations.

Occultation Portal is a web-based astronomical archive and analysis platform for the fast, efficient, and centralized management of occultation observation campaigns coordinated by the Lucky Star Project. This platform is a scientific initiative conducted in partnership with the LIRA - Observatoire de Paris PSL (France), Instituto de Astrofísica de Andalucía (Spain), and The Federal University of Technology – Paraná (Brazil).

This project is powered by the following FREE/open source softwares.
