Beginning in late 2022, the Vera C. Rubin Observatory will carry out the widest and deepest optical survey to date, the Legacy Survey of Space and Time (LSST). LSST will capture the entire available sky every few nights in 6 broad-band filters (ugrizy), providing an unprecedented dataset to explore the Solar System’s inventory. The LSST’s Solar System Processing (SSP) will run daily and detect moving Solar System bodies out to ~200 au. SSP requires the input of sources detected in LSST’s difference images. The LSST image subtraction pipeline uses a master template representing the static sky, periodically (re)built during Data Release (DR) production. The first set of high fidelity templates (and the start of moving object/transient science) is therefore expected post-DR1, a year after observing starts. The Rubin Observatory is evaluating options for accelerated incremental template generation (e.g. on a monthly or weekly basis) in LSST Year 1 Operations. We highlight some high impact Solar System science opportunities that this change would enable.
