Overview

ℹ️

Saurer 6 is a sparse, very loose object of intermediate C3 quality. Its parallax locates it at a large distance, above the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, old cluster (see Parameters). It is poorly studied in the literature.

Very distant Moderate extinction Massive Near-solar metallicity Old

Perren et al. (2022)
The CMD shows a wide and short main sequence with the TO at approximately G=18 mag. The giant branch is quite scattered although the RC is evident. The high star density in the region may explain the main sequence widening. Frinchaboy 2002 used CCD VI photometry and found 2 Gyr and 9.3 kpc. ASteCA gives 1.4 Gyr and 9.2 kpc, in close agreement. WEBDA and OC02 report the same distance as Frinchaboy; MWSC gives a smaller 7.3 kpc.
