Environment - Non Weather Related; Procedure
On the arrival into Atlanta we experience a severe wake turbulence event. Aircraft banked 45 degrees each side. I clicked the autopilot off and counteracted the rolling motion with full opposite aileron. First Officer communicated to ATC we needed to level off at 6000 ft due to wake turbulence. ATC then communicated that a 747 had just been through there landing on the parallel. We could see the 747 ahead and [to our] right landing; as well as a company CRJ 200 12 o'clock. In proper separation between us and the heavy considering current wind conditions; additional separation or off-setting the arrival course could have helped. 'Caution wake turbulence' would have prepared us.
CRJ Captain reported experiencing a 'severe' wake turbulence event on arrival into ATL in trail of a B747.
