After the announcement by F. Manzini, V. Oldani, A. Dan, Stazione Astronomica di Sozzago, Italy, R. Crippa, Osservatorio di Tradate, Italy, and R. Behrend, Geneva Observatory, Switzerland report that  CCD-images taken on 30 august 2014, show a second nucleus of comet C/2011 J2 (LINEAR) . After this announcement i re-examine my CCD-images of this comet and could find a second fragment near the nucleus of this comet. After image enhancement en processing I could see more clear this fragment en did some measurements on the CCD-images, like you can see below in my ccd-images taken on 20 august 2014 of this comet.
