Beginning late 2022, the Large Synoptic Survey Telescope (LSST) will produce a nightly stream of ten million public alerts that will disseminate new information about transient, variable, and moving objects within 60 seconds of readout. A small number of "community brokers” will receive the full LSST alert stream, add scientific value, and provide science users the ability to identify targets of interest and trigger follow-up observations. Letters of Intent (LoI) from all teams who plan to propose a community alert broker were received by May 15, 2019 (https://ldm-682.lsst.io/).
This workshop will bring together LSST Project personnel, representatives of the LSST Science Collaborations, individuals with relevant past experience, and the proposers of community brokers (at least one representative from each team that submitted an LoI). Topics of discussion will include LSST-broker interfaces, architecture and technology choices, the broker selection process, policy issues, science use cases and expectations, and development progress from precursor surveys.
This workshop will facilitate the success of community brokers by opening the lines of communication with the LSST project, providing feedback from representative science users, and enabling sharing of technical experience and organizational information between all parties, as well as learning from the experiences of precursor surveys. The workshop Science Organizing Committee will facilitate the writing of a white paper summarizing the outcomes and conclusions of this workshop to serve as a reference for LSST community brokers going forward.
Includes full meeting agenda, slide deck for "pitch" introductions, and suggested contents for talks from LOI-submitters and Science Collaboration representatives. This Google Drive will be used for all workshop-related materials.

All sessions will be held in downtown Seattle at the Sheraton Grand Seattle hotel. A block of rooms has been reserved at a group rate, and participants will be sent information about how to book these rooms after they have registered (deadline: Fri May 24).
The venue is right in the middle of downtown, and the restaurant options are diverse in terms of costs and options.
We anticipate that most participants will arrive by air to the Seattle-Tacoma International Airport. The best way to reach the hotel is by public transit: take the Link Light Rail from Sea-Tac Airport to Westlake Station (northbound direct towards the University of Washington, no transfer). It's a 40 minute ride, and the $3 one-way tickets can be purchased by cash or credit card from automated machines at the stations. Once downtown, walk the two blocks from Westlake Station to the Sheraton Grand Seattle hotel.
The weather conditions in June should be nice, but are difficult to predict in advance! It is best to check the forecast close to the time of your visit and always pack a raincoat, just in case.
Staying for the weekend? Seattle has many wonderful options for our guests. Some of the top tourist attractions are the Pike Place Market, the Seattle Aquarium, the Museum of Popular Culture, the Living Computer Museum, and the iconic Space Needle, most within walking distance of the Sheraton. If you're more interested in a venture out onto the waterways or the wild outdoors, there is a very wide variety of options for that as well.
