Bulletins

Bulletins are brief updates about SRS Open Science Platform components, such as tooling, datasets, and sensor networks. A bulletin can be about dataset releases, sensor deployments, releases of new skymaps or other higher-level data products, just to name a few. Below is a searchable keyword-based list for all bulletins.

It is expected that this list will grow faster than the larger news articles, as they are more brief and rapid in nature. Note that we have created bulletins going back to June 2024, just to populate this with what has happened since then. This feature was released in February 2026.
