Colibri can support the interpretation of astronomical data. The sensitivity of the next generation high-energy gamma-ray observatory, the Cherenkov Telescope Array (CTA), will surpass current instruments by about an order of magnitude. It will thus provide unique opportunities for the study of transient phenomena at high energies.
Flares of known stable astronomical sources and transient sources can occur on different timescales. The discovery potential of both serendipitous observations and multi-messenger and multi-wavelength follow-up observations could be maximized with a tool which allows for quickly acquiring an overview over both stable sources and transient events in the relevant phase space. We here present Colibri, a prototype for such a tool. It is based on notices forwarded by NASAs Gamma-ray Coordinates Network (GCN) and various catalogues of known sources, and yields a graphical representation with a summary of the relevant data to allow for the fast identification of changes in observed sky regions, and for analyses of those.
In this contribution, the key features of the graphical interface are presented. Details about the used data resources are explained. Current and possible future implementations of Colibri will be discussed.
