A satellite tower called the Flight Data Sector on the dial line to report that a Aircraft X reported extreme turbulence at 2300 feet. Tower also said the pilot reported a 60 degree bank and loss of 200 to 300 feet of altitude. The Flight Data controller passed that information to me while I was the Supervisor in charge. It sounded like wake turbulence to me so I looked at the falcon replay and observed a VFR target at 2300 feet transitioning the Class D and Aircraft Y on a base leg 3000 feet descending. The replay showed the VFR target turn abruptly and lose 100 feet of altitude. I called the satellite airport Tower back to confirm the callsign of the VFR aircraft and how the pilot described the turbulence report. I also called the VFR aircraft's Operations to confirm the event; the pilot said it felt like wake turbulence. Furthermore; the individual I spoke with at Operations confirmed that they were going to file a report through their internal reporting system. As larger aircraft are introduced in the NAS there is a need to have procedures in place to mitigate wake events. As heavy and super category aircraft descend into the main airport the Class D airspace of a satellite airport could be compromised by the wake turbulence created. I do not have direct knowledge of the procedures currently in place between but those who do should look into this event and the possibility of ensuring that future wake related events like this do not occur.
A TRACON Supervisor reported a light aircraft in a satellite airport airspace reported a wake vortex encounter with a Super aircraft on approach to another airport.
