is a very interesting open clusters visible by naked eye. The
integrated brightness is mag. 3.3, and is located in Carina. The
position in the sky is nearly on the prolongation of SMC and LMC; at a
rough naked eye observation may resemble like a third and very small
Magellanic cloud, so that can be named as MMC (Micro Magellanic Cloud).
