Munkácsy appears near the terminator, the division between the dark nightside and sunlit dayside of the planet, in this image taken during MESSENGER's first Mercury flyby. Munkácsy originally had a double-ring basin structure, but most of the inner ring was buried when the basin was flooded with volcanic lava. Only a few remnants of the ring poke up through the lava, although low ridges in the lava seem to trace out much of the rest of the ring's circumference. This small impact basin was recently named for Mihály Munkácsy, a Hungarian painter (1844-1900).
