Abstract

Multicolor photometry and MK classification spectroscopy have been obtained for the sparse collection of stars known as van den Bergh and Hagen cluster No. 99. The group appears to be a true open cluster composed of at least 24 members with a mean reddening of E(B -V) = 0.05 mag, a mean distance modulus of 8.30 mag and an age of approximately 108 yr.
