✍️ Rubin #CommissioningNotes, entry 5️⃣: we’re making gains💪

Efficiency has been the name of the game for the past two weeks! As our team addresses the causes of data-taking interruptions, fewer interruptions occur—meaning even more data overall📈

Read on for recent achievements🧵

Eye to the sky…on-sky engineering tests have begun at NSF–DOE Rubin Observatory using the world’s largest digital camera! 🔭🧪

After installing and testing the LSST Camera, we turned the telescope to the sky—a moment 20 years in the making!

With that, Rubin #CommissioningNotes are back ✍️

✍️ Rubin #CommissioningNotes, entry 2️⃣: when you turn it on and it works 🤌

Initial tests with Rubin's test camera, ComCam, showed the telescope was already nearly aligned before even looking at the sky — a testament to decades of work! 🔭🧪

Commissioning is the process of testing, troubleshooting, and aligning the different parts and software of Rubin into one functional system.

Stay tuned for updates & details, and join us on this exciting adventure toward a complete Rubin Observatory as we log progress in our #CommissioningNotes! 🔭

Welcome to Rubin's #CommissioningNotes! Entry 1️⃣: we're in full swing!

Ok, but what's "commissioning?"

Rubin Observatory is the result of millions of hours of work by thousands of people around the world -- and now all that work is coming together! 🔭🧪

Rubin #CommissioningNotes ✍️: we’re one month into on-sky testing with the LSST Camera!

The letter of the week was “c”: calibrations, computing, commissioning, and sCattered light investigations.

(Yes, we stretched that last one—but the science is solid!) 🔭🧪

✍️ Rubin #CommissioningNotes, entry 4️⃣: whoaaa, 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 🔭🧪

Read on for last week’s highlights! 🧵

Rubin #CommissioningNotes ✍️: On-sky engineering tests continued this week!

The team started tuning image quality control systems in real survey-like conditions. LSST Camera is performing smoothly and has captured over 5,000 sky exposures so far (that’s 15 trillion pixels!) 🔭🧪

✍️ Rubin #CommissioningNotes, entry 3️⃣: progress continues!

Our team had some exciting accomplishments last week with Rubin's test camera, ComCam:
🏅the best image quality measured so far, and
🎨 data taken of the sky in five of Rubin's six wavelength filters

Rubin #CommissioningNotes ✍️: Winter is coming 🥶

It was a chilly week this week at Cerro Pachón in Chile. But our team kept up their commissioning and calibration work, continuing to bring NSF–DOE Rubin Observatory up to full operation as a cohesive system. 🔭🧪

Rubin #CommissioningNotes ✍️: The data deluge from NSF–DOE Rubin Observatory is coming!

Rubin captured over 500 exposures per night across 3 nights this week, using its automated observation scheduler — that’s 20x more than during the 7 week period with the engineering camera last year!🔭 🧪
