9373 Hamra           Discovered 1993 Mar. 19 at the European Southern Observatory in the course of the Uppsala-ESO Survey of Asteroids and Comets.
Hamra is a small parish on southern Gotland. The general store, famous from the song snabbköpskassörskan, has now closed, as have most of the other general stores in the Gotland countryside.
