Latysev 1:
„This is a possible moving cluster of only five stars, first suggested by Latyshev (1972). It was identified by considering the space motion of several nearby (GJ, or Gliese Catalogue) stars in this area. These 5 stars are spread over an area of 5˚ by 6˚, and are GJ 112 = HD 17190, GJ 113 = HD 17382, GJ 113.1 = VY Ari, GJ 118.2A = HD 18143 (one of three components), and GJ 120.2 = 51 Ari. The magnitude range is from V = 6.72 (51 Ari) to V = 7.81 (GJ 112), summing to V = 5.45 and B = 6.21.”
„It is interesting to note that three of these stars, GJ 112, GJ 113.1 and GJ 120.2, were also identified as members of a possible moving cluster “[AO84] III”, in a later study by Agekyan and Orlov [1984]. Therefore, if both of these groups are considered as real physical groups, Latyshev 1 should probably be considered a part of [AO84] III.”
