IRAS 21282+5050 is very compact planetary nebula with a substantial molecular shell. It is carbon-rich and exhibits infrared features attributed to PAH molecules. It has a far infrared color temperature higher than almost all other planetary nebulae, with IRAS flux ratios similar to low color temperature evolved stars. We present VLA images of IRAS 21282 at wavelengths of 2 and 6 cm (with FWHM beamsizes of 0.5” and 0.9”, respectively).
