Multicolor photometric and spectroscopic observations of the van den Bergh and Hagen cluster no. 99 Multicolor photometry and MK classification spectroscopy have beenobtained for the sparse collection of stars known as van den Bergh andHagen cluster No. 99. The group appears to be a true open clustercomposed of at least 24 members with a mean reddening of E(B-V) = 0.05mag, a mean distance modulus of 8.30 mag and an age of approximately 100million years.
