Historical observations

John Herschel (1847) Cape Observations

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "a small but brilliant group of 6 or 8 large stars, 8, 9 and 10th mag, within a very small compass."

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NOCL S.

Moffat, AFJ & Vogt. N. (1975)

This cluster was first recorded by Moffat and Vogt.

Moffat, AFJ & Vogt. N. (1975) "Southern Open Star Clusters IV. UBV-H-beta Photometry of 26 Clusters from Monoceros to Vela." Astron.Astrophys.Suppl., 20, 85-124. [image, table]

Anon around BD-16°1999 = Bo 4 + 5. Two previously uncatalogued groups are apparent here as indicated in figures 20abc: Group A = Bo 4 comprises several stars in an obvious concentration in the southern part of figure 19 but also a few stars distributed elsewhere amongst group B (Bo 5). Group A is a foreground cluster with: d = 0.87kpc.

Modern observations

Steve Coe

Steve Coe, observing with a 13" f/5.6, notes: "Pretty faint, small, 8 stars counted at 135X. There are two pretty bright stars, approximately 9th mag and 6 other stars of mags 11 to 13 in this small asterism."

Steve Coe, observing with a 13" f/5.6, notes: Pretty bright, pretty large, somewhat compressed, 22 stars counted at 135X.

Contemporary observations

(no date)

This grouping is situated just north of Bochum 5 and I do made a sketch of the area. A slight X shape with a handful of stars that runs out to the NE. Faint stars can be between the brighter ones. Bochum 5 consist of only about 6 faint stars in a short string. I had a look for the nebulosity to the east of this cluster and just suspect it. Will go back again.
