What is included?

Below you will find compressed tar archives of ZTF event alerts (observations detected in image differences). Each tar file contains alerts collected in the given night (UTC-based), with each alert stored in a separate file in the AVRO format. To get you started, we offer a repository with few basic utilities for reading AVRO-serialized data, as well as an example Jupyter notebook.

Why this service?

We are providing this archive as a stop-gap measure until public event brokers capable of receiving and redistributing the ZTF alert stream come online. We expect this by the end of 2018.
