There are many various sources for tracking and displaying Flux of black holes and neutron stars. The issue here occurs from the inconsistency of information through out the various services. Our team strives to unify and gather all the needed data, in order to achieve a consistent information stream providing the user with the most accurate data concerning flux changes and their occurrence. As a feature, you get all the needed information on a single web service at the tip of your fingers.

This project is solving the Transient Watch – Daily News on Active Neutron Stars and Black Holes on Your Mobile Phone challenge.


The team consists of 3 Front End Developers, 3 Back End Developers, an university lecturer/enthusiast astronomer and an android developer.

The thing that brought us all together as a team is the Plovdiv hackerspace.- Hackafe.
