History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 6360. As with NGC 6335, which see, there is no nebulosity making up this "object." Instead, JH saw the bright background of the Milky Way broken up into many patches of nebulous light by the dark nebulae lacing the area with dust.

The position I've adopted for NGC 6360 is about a minute of time west and 7-8 arcmin north of JH's position (like N6335, in an area pretty well covered by dust). This is the brightest cloud of stars in the area, approximately 12 arcmin across. JH's comment, "The nebula is in patches of very great extent," makes it clear that this particular cloud is not the only one he saw in the area.

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 portion of the milky way which is decidedly nebulous, and by no means rich in large stars. The nebula is in patches of very great extent."

Published comments

Bailey, S.I. (1913)

Bailey, examining a Bruce plate (Harvard Annals, Vol 72, No 2), describes it as "Milky Way, rich in stars, no nebulosity seen."

Cederblad, S. (1946) [VII/231]

Ced 143 (NGC 6360)

Position (1900): RA 17 19, Dec - 29 54

Star: ?

Spectrum of nebula: (not classified)

Classification: Nebulae without definite relation to certain stars - Background veil of a nebulous region (eg. the Taurus veil)

Size: (not given)

Notes: "NGC 6360 = GC 4299 = h 3685. Disc. 1834. R. Potsdam spectral DM Area 157 is situated in this region. (31) announces that no nebula is to be seen on a plate containing this region."

Sulentic & Tifft (1973)

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

(no date)

Verslag v

Ophiuchus; 17h 25m 24s -29 59.7

Rather speckled and busy star field strewn with a variety of stars. On account of their apparent closeness to one another they appear to resemble a part of the Milky Way.

(no date)

Alldays (22.50S, 20.12E, 770m).

12-inch f/10 SCT (95x, 218x)

Rather speckled and busy star field strewn with a variety of stars in a two point to north grouping. PK 356.8+03.3 is just 9' to the NE. On account of their apparent closeness to one another they appear to resemble a part of the Milky Way? A handful of faint stars (11-12Magnitude) just NE of 7.5 star which is slightly elongated N-SE. More or less 8' in size with a string to the grouping west devide another group of a few stars with a yellow 7.2 Magnitude star involved.
