Description
During its PV phase eROSITA observed a ~100 deg2 field to the final depth expected after eight all-sky scans. The XMM Atlas survey is covered in this field. Between these data sets, we search for dramatic flux changes in AGN which would indicate AGN ignition/shut-down. I will present a few candidate events. We will extend this work using the data of all individual eight all-sky surveys by eROSITA. The number of expected events and the clean selection of sources allows us to compute the probabilities that such changes happen. This will result in observational constraints on the AGN duty cycle. For selected events we will trigger follow-up observations (e.g., XMM, VLT).
