MARS provides access to all public alerts issued by ZTF since the start of the public alert stream on June 1, 2018. Subsets of the alerts, filtered by selectable constraints, may be identified and downloaded, either through this webpage or using the underlying API. Alerts are ingested as they are generated by the ZTF survey and are made available immediately, which is reflected by the "Latest Alert" value below. Users are advised to limit their request frequency to a reasonable time period, preferably allowing at least 5 minutes between requests. In addition to our own help page, users should refer to the ZTF website and the ZTF Alert Archive for documentation on ZTF and the generation of alerts.

The following table lists ZTF alerts in descending order by JD. Use the filters on the right to narrow down the results to interesting candidates. When the results look good, add ?format=json to the url. You can now access this url to retrieve the full data and use it in your scripts. You can access an alert's previous alerts by visiting /<id>/ where id is the value of the lco_id key in the json view or by clicking the id link in the table.

See the help page for descriptions of the table values and available filters.

The ZTF survey was down for maintenance on Oct 10th, 2018 and resumed normal operations on Oct 31st, 2018. Please be aware that there are no alerts for that period of time.
