We are excited to announce the release of Astro-COLIBRI v2.19.0, packed with new features and enhancements for transient astronomy and catalog exploration.
Enhanced Lightcurves for Optical Transients
- Combination of multiple ATLAS observations for better data integration and visualization.
- Upper limits added for both ATLAS and ZTF observations.
- Custom lightcurves are now available for any sky position, independent of transient events.
- Integration of data collected by the RAPAS amateur astronomer network (restricted to RAPAS members).
- Details in our documentation
TeVCat and 4FGL-DR4 Catalog Updates
- TeVCat and 4FGL-DR4 databases updated to the latest versions.

- Beta vs Energy Peak for 4FGL sources with significance > 20.
- Flux vs Spectral Index for TeVCat sources containing this information.
Minor Improvements and Bug Fixes
- Team page updated on our website.
- Added link to the Lasair broker for ZTF-detected transients.
- Improved handling of confidential information requests.
- Restricted group for CTAO/LST-1 users, including submission of ToO requests.
