Outbursts of SMBHs have significant impact on structure formation and evolution. Their imprint on ICM {e.g., shocks, cavities, elevated entropy} provides an historical chronicle of the SMBH activity. Because of the expected bigger impact of AGN heating on the group gas than the cluster gas, group cool cores are ideal places to study SMBH outbursts. We propose an 89 ks observation of the most X-ray luminous group cool core at z<0.05 {also the second brightest one} that only has 7 ks Chandra data. It also hosts one of the most spectacular Ha filaments in nearby groups. The requested ACIS data, in combination with the joint VLA and HST observations, will be used to examine cavities, shocks, the relation between gas in different phases and star formation, and the AGN activity history.;
