3.2 Gigapixels:
We built the largest (declassified) camera ever built
to look farther and wider into the sky than ever before
In 2026 we will begin observing the sky with 1000 images every night for 10 years
0.2'' / pixel, 6 filgers (ugrizy)

Large FoV (10 sq deg - easly cover 100 sq deg in full)
6 filters (5 available on any given night)
deep observations (r~24 in 30 sec, up to 180 sec)

The Rubin LSST ML-Reliability Score (aka real-bogus)
accuracy 98.06%, purity 97.87%, completeness of 98.27%... on simulated data
- requires instantaneous inference
- limited computational resources (CPU)
- evolving data quality
- limited ground truth data (e.g. no variable stars in training)

ALERTS HAVE STARTED!
Why not always? We deliver alerts on DDF+Virgo when we run the survey in survey mode (=not engineering tests)
Why not everywhere? Limited templates available - template foorprint increasing
~7M alerts per night
*Conservative ML-reliability scores for now because the infrastructure (Rubin and brokers) is still under development

A community of practice funded on principles of Equity, Inclusivity, Cooperation
is a word I am borrowing from Margaret Atwood to describe the fact that the future is us.
However loathsome or loving we are, so will we be.
Whereas utopias are the stuff of dream dystopias are the stuff of nightmares, ustopias are what we create together when we are wide awake
US-TOPIA
