✍️ Rubin #CommissioningNotes, entry 4️⃣: whoaaaaa, we’re halfway there 🎶

Halfway through data-taking with Rubin’s test camera, that is. Our team has continued to make great progress testing Rubin’s systems with ComCam.

=== Highlights ===

🎨 The team got data using all six of Rubin’s wavelength filters for the first time!

💨 The team also continued increasing the telescope’s speed as the systems that manage the forces felt by the mirrors continued to show good response.

✨ With repeated data of the same sky area, the team successfully ran the software that will identify cosmic changes in Rubin's images, called the Difference Image Analysis pipeline, end-to-end for the first time—a great step toward the goal of delivering 10 million alerts per night about cosmic changes once Rubin begins to #CaptureTheCosmos in 2025 🥳

2024-11-22 On-sky Commissioning Update

It is the fourth week of on-sky commissioning with ComCam, and we are now about halfway through the planned duration of the campaign. Active Optics System (AOS) commissioning continues to test both the closed loop and open loop systems. The AOS closed loop is now running with more than 90% of the optical degrees of freedom enabled, including the camera and secondary mirror (M2) hexapods that control the rigid-body relative positioning of the optics, and all of the lower order bending modes for ...

@VRubinObs Thanks for the update. I wasn't aware before that the telescope can create such nice startrail images.🤔 I thought that was doable with cheaper standard cameras. 🙄
