Architecture¶

Obsloctap is a web service written in Python that publishes a JSON representation of the observing schedule and for past observations. Obsloctap obtains information about upcoming observations from the lsst.sal.Scheduler.logevent_predictedSchedule Kafka topic on the USDF Summit Sasquatch. This is replicated from the Summit to the USDF using MirrorMaker.
