An odd and pretty cluster framed by three 7.5 magnitude stars in a 7' equilateral triangle, a notable 3' clump of 9-12 magnitude stars at the center of the triangle, the clsuter is 1° east of ηSco

Most of the stars share a similar parallax of 0.6-0.7 mas in the Gaia DR2 data except the northwest star of the triangle HD156189 which is much closer to us with a parallax of 8 mas
