Optical features of NGC 4696 observed in 1982 are reported. Blue and red filtered long-interval exposures were made, together with CCD camera observations using filters for redshifted H-alpha + forbidden N II and forbidden S II. A continuum band around 6900 A was detected, together with filaments south and west of the nucleus. Evidence that a reddening absorption feature previously detected was connected to the filamentary structure was found. It is suggested that the object is actually cooling intracluster gas accumulating on the central galaxy of the Centaurus cluster. Future IUE observations will be performed.
