Description (description supplied by Sakib Rasool) PN G237.9-07.2 is one of 1200 planetary nebulae discovered in the MASH  (Macquarie/AAO/Strasbourg Ha) survey. It has a size of 11x10 arcminutes and is currently classified as a possible planetary nebula due to a lack of spectra. However it responds reasonably well to imaging with both Ha and OIII emission present.
