# [Lasair: A UK Alert Stream Broker]({%lasairurl%}) [*Lasair*]({%lasairurl%}) is being developed by The University of Edinburgh, Queen\'s University Belfast, and Oxford University to serve transient alerts from the [Rubin Legacy Survey of Space and Time (LSST)](https://rubinobservatory.org/) to the astronomical community. *Lasair* (pronounced '*L-AH-s-uh-r*') means flame or flash in Scots and Irish gaelic. To prototype functionality needed to process transient event alerts from LSST, Lasair has been processing and serving data from the public stream of the [Zwicky Transient Facility (ZTF)](http://www.ztf.caltech.edu/), which is releasing a transient alert stream in a format similar to that envisaged for LSST. We thank ZTF for access to this valuable public data stream. If you make use of [Lasair]({%lasairurl%}) in any of your work, please remember to cite our paper: [R.D.Williams et. al., Enabling science from the Rubin alert stream with Lasair](https://doi.org/10.1093/rasti/rzae024), RAS Techniques and Instruments, **3**,1, 362 (2024).
