"This cluster was observed because of its coincidence with the Cepheid variable SV Cru. ... d = 1.15 kpc. Six stars may be red giant members. Ru 97 is intrinsically too faint to be related to SV Cru."
1997-03-24, Monday. Jonkershoek. 11x80 tripod. Full Moon. Not found.
12-inch f/10 SCT (95x 218x)
The grouping is situated barely a degree north-west of theta Crucis. I pick up a knot of faint stars about 10 arc-minutes south-west of the indicated position. The star field are very busy with faint pin-point stars.
Sky Conditions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.
The stars in this open cluster is well detached and that this cluster consists of 10th to 12th magnitude stars arranged in a concentric circular motion area of which I have counted 21 stars in this cluster and that in this open cluster there is a blue star being situated WNW which is composed of a 6.5 and two 7th magnitude stars.However this open clusters stars are nearly as bright as each other and that this clusters stars are not separated.This open cluster measures 11.2'x 9.3'.
