2.31.0
August 30, 2026
Home screen widgets are here! Add Astro-COLIBRI, Latest discoveries, Observable tonight or Watchlist to your Home Screen or Lock Screen and follow the transient sky at a glance. Every widget comes in several sizes and follows your colour theme and language. Also new in this version: • Fermi-LAT Light Curve Repository: long-term gamma-ray light curves of more than 1500 catalog sources, one tap from the source, with CSV and VOTable export. • Cone searches now cover the full 90% localisation region of gravitational wave, Fermi-GBM, IceCube and MAXI alerts instead of a fixed circle. • Long-term visibility: darkness, moonlight and observation windows for any period up to a year at your observatory. • Host galaxy cross-match rebuilt around GLADE+, the DESI Legacy Surveys and SDSS quasars, with an image cutout for every match. • New MAXI/GSC X-ray transient alerts, and all public gravitational wave alerts from O1 to O3 are visible again. • NMMA can now fit and rank up to 16 supernova and kilonova models on the same event. Plus a public alert stream over Kafka, updated TeVCat and Fermi-LAT catalogs, and a range of smaller improvements and bug fixes.

FAQ
What types of astronomical events does Astro-COLIBRI alert users about?
Astro-COLIBRI provides real-time push notifications for a variety of astronomical events, including Gamma-Ray Bursts (GRBs), Gravitational Waves (GW), High-Energy Neutrinos, and Supernovae. Users can filter these alerts based on their custom criteria.
How does Astro-COLIBRI provide multi-wavelength context for events?
The app automatically places detected events into their Multi-Wavelength (MWL) context by integrating data from major observatories like Swift and Fermi, as well as catalogs such as 4FGL and TeVCat.
Can Astro-COLIBRI help with planning observations?
Yes, Astro-COLIBRI includes advanced planning tools to assess observing conditions at professional observatories or custom coordinates. This includes information on Sun/Moon positions, altitude plots, and weather assessments.
Does Astro-COLIBRI support collaboration between professional and amateur astronomers?
Absolutely. Astro-COLIBRI is designed for Pro-Am collaboration, offering dedicated support for amateur networks. This allows for the submission and tracking of observations directly within the global community.
What are the subscription options for Astro-COLIBRI AR?
Astro-COLIBRI offers an AR (Augmented Reality) version with subscription plans. Users can choose between a monthly subscription of $2.99 or an annual subscription of $29.99, both offering a 7-day free trial.
How frequently is the data in Astro-COLIBRI updated?
The app provides real-time photometry and lightcurves that are updated twice daily. This ensures users have access to the most current observational data for transient events.
Is Astro-COLIBRI suitable for younger users?
Astro-COLIBRI has an age rating of 4+, making it accessible for a wide range of users. Its educational content and interactive features can be beneficial for learning about astronomy.
