Globular cluster Lynga 7 was first cataloged by G. Lynga (1964) as open cluster and classified as of Trumpler type II 2 p. It is listed again as open cluster by van den Bergh-Hagen (1975) as vdB-Ha 184.
It was only in 1993 that Ortolani, Bica and Barbuy brought up evidence that this object might be a globular cluster. They investigated its color-magnitude diagram, which resembles that of a globular, but derive a significantly lower age than for the usual globular clusters, and classify it as a disk globular cluster. Similar results were obtained by Tavarez and Friel (1995). Meanwhile, Lynga 7 is generally regarded as globular.
Lynga 7 is one of the more "metal-rich" globulars, i.e. its stars contain significantly higher concentrations of elements heavier than Helium than average globulars, more similar to the composition of our Sun.
