Improved images and a newly determined spectrum from 80 MHz to 15 GHz have clarified the nature of the radio source G0.33+0.04 at the Galactic Centre. Its non-thermal spectral index and its shell-like morphology favor an interpretation that this is a supernova remnant. Furthermore, the absorption characteristics of the continuum spectrum at the lowest frequencies and its elongation along the plane suggest that, like Sgr A East, it is in physical proximity to the Galactic Centre (see http://rsd-www.nrl.navy.mil/7214/weiler/dragonfarm.html for an image)
