Abstract

In the vicinity of the southern hemisphere giant H II region NGC3603 we discovered a new planetary nebula: PNG291.4-00.3 located at RA[J2000.0] = 11^h14^m32^s.1+/-0^s.3 and DEC[J2000.0] = - 61^o00^ scriptstyle ' 02^ scriptstyle '{('}) +/-1^ scriptstyle '{('}) . Monochromatic images reveal a central ring-like structure with onsets of arc-like filaments which might outline a bipolar outflow. Optical imaging and spectroscopy confirm that the emission line object found on WFI images is a genuine planetary nebula, and that it is a high-excitation bipolar Type I object.
