[AMSAT-BB] EN57/58 on JO-97 Satellite

I worked a station on JO-97 Satellite on May31,2021 at 1652 utc time who was in Grid EN57/58 I must have received the Call sign wrong as I couldn't find it on QRZ.COM It ended in CT but I think I got the prefix wrong. Did anyone else work this staion that could give me the prefix ?? Thanks JACK KC7MG DM42
