Eponym Johann J. Balmer

Balmer is the lava-flooded remains of a lunar crater. Only the heavily worn southern and eastern sections of the crater still survive; the remainder being overlaid by a lava flow that joins to the nearby mare. Balmer lies to the east-southeast of the crater Vendelinus.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Balmer.
