Scientific paper

A search for planetary nebulae was carried out using candidates selected by their infrared colours and 5 GHz radio emission. One new planetary nebula was identified on the basis of its small angular size, strong [OIII] emission and infrared colours. Another object, known as the possible planetary nebula Wray 16-28, is similarly identified as a planetary nebula. An undiscovered AGN was also found, and is classed as a Seyfert 2 Galaxy on the basis of its strong OIII emission, linewidths of approx. 500 km/s, and 5 GHz radio flux. Low-resolution optical spectra are presented and distance estimates discussed.
