The sample precursor alerts we released this summer do not yet have known Solar System objects labelled. To fill that gap, we are providing a sample of alerts from simulated solar system objects. The simulated alerts only have a few fields populated, but they may be useful in assessing how to handle alerts from moving objects.
Information about the sample alerts and how to retrieve them is available at this link: https://github.com/lsst-dm/sample_alert_info.
