Update on 3I/ATLAS in Rubin Data

Hi everyone,

As many have heard, a third ever interstellar object – 3I/ATLAS – was discovered last week by the ATLAS survey team (congratulations!). The discovery and the object’s location in the sky have prompted questions on whether Rubin has seen it.

This is a quick update to confirm that Rubin has seen 3I/ATLAS in our commissioning data. The team is working hard to process and release the images with the object. We aim for this to happen soon, but don’t have a timeline to share yet.

Stay tuned – more soon, I hope!
