Rubin/LSST Infrastructure for Time-Domain and Target of Opportunity Astronomy

The Vera C. Rubin Observatory’s Legacy Survey of Space & Time (LSST) will be a 10-year optical and near infrared survey of the southern sky, expected to start operations in mid 2025. Exploring the transient optical sky is a key LSST science driver; LSST will issue 1 million alerts from transient, variable, and moving sources via a world-public alert stream. Seven full-stream “community brokers” are preparing to receive the LSST alert stream, add value and redistribute it to the scientific community. In this talk I will review the time-domain infrastructure for exploiting the LSST data and enabling follow up observations. I will also discuss Rubin’s plans for a Target of Opportunity (ToO) program and plans for processing of ToO data in early operations
