Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

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.
