Moffat, AFJ & Vogt. N. (1975) "Southern Open Star Clusters V. UBV-H-beta Photometry of 20 Clusters in Carina.." Astron.Astrophys.Suppl., 20, 125-153. [image, table]

"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."

Location: Alldays

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.

Location:Perdeberg.

Time:9:53pm.

Sky Conditions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.

Instrument:12-inch Dobsonian.

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'.
