Alert and network statistics

This pages lists the statistics on released alerts, and on observations by the ground-based network. The number of observations and list of most productive observatories are based on the reports provided by the observers through the Gaia-FUN-SSO alert pages (not from MPC reports).

Statistics on alerts and reports

Summary of released alerts
First alert 2016-12-01
Current last alert 2022-05-23
Number of alerts 2309
Summary of ground-based observations
Number of observations 343
Reported candidates 326
Reported attempts without identification 17

The number of observed candidates is larger than the actual number of Gaia alerts recovered from the ground as unknown SSOs may be present in the same field of view and mis-attributed to the alert.

Successfully recovered alert from the ground

The list below contains the minor bodies that have been discovered by Gaia, observed from the ground, and successfully confirmed. Some candidates observed from the ground have indeed been shown to be unknown minor bodies, different from those discovered by Gaia.
