Radio image of the Sgr A East supernova remnant at 6 cm wavelength (Zhao et al. 2016). Coordinates are J2000. The thin green ellipse shows the approximate outline of the expanding shell. The location of Sgr A* is marked with a magenta plus (+). The bright Sgr A West HII region surrounding Sgr A* is in the near foreground of Sgr A East. The compact HII regions constituting G-0.02-0.07, appearing at the left, are embedded in the 50 km s⁻¹ molecular cloud with which Sgr A East is interacting.
