Historical observations

Dunlop, James (1827)

James Dunlop discovered this 8th mag globular cluster from Paramatta, New South Wales, and included it as No. 225 in his catalogue of 1827. Using a 9-inch f/12 telescope, he described it as "a pretty large rather bright round nebula, 3' or 4' in diameter, very moderately condensed to the centre,resolvable into extremely minute stars; the stars are more scattered on the south side."

John Herschel (1847) Cape Observations

Observed by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "globular cluster, bright, large, round, very gradually much brighter in the middle, diam. in RA = 50 second, diam 7' or 8'; stars all seen, 12..16th mag with outliers extending a good way." His second and last observation reads: "globular cluster, irregularly round, pretty bright, pretty large, gradually brighter in the middle, 4', all sharply resolved into stars 14..17th mag."

NGC/IC Dreyer (1888, 1895, 1908)

The NGC calls it "considerably bright, large, very gradually much brighter towards the middle, well resolved into stars which are of magnitudes 14..17."

Modern observations

Bennett, Jack

Bennett, including it as No. 95 of his "comet-like objects" catalogue, rated it as a circular extended object.

Hartung, E.J. (1968) Astron.Obj.South.Tel

Hartung writes "This globular cluster in a fine field extends with outliers about 4' across; it rises broadly to the centre and is beautifully resolved into faint stars on a hazy ground. This resolution is quite clear with a 6-inch telescope but a four-inch shows only granularity. The edges are very irregular with arcs and rays of faint stars."

ASV Journal (1971)

ASV Journal Vol 24 No 3 June 1971: "slight central condensation."

Contemporary observations

Auke Slotegraaf

1982

In a 15.5-inch telescope, the globular appears very irregular, a-typical, and looks more like a concentrated open cluster with some nebulosity. Stars resolved right to the centre; about 7 stars are visible across the disc of the globular. The brightest part of the globular has a curved appearence, curving towards the north-east. There are absolutely no outlying stars, and its irregular form is quite striking.

1997 April 05

1997 April 05, 01:00 SAST, 11x80 tripod-mounted binoculars. Near Ara-Apus-Pavo border. Lies in a very rich field of large and small stars. Broad, circular fuzzy glow, easy to spot a short hop from alpha TrA.

NGC 6362 vg mag8

Very densed round, lot of gasius surroundigs. Stars evenly spread out.

Location: Campsite (South 23 16 East 29 26).

Sky conditions: Clear, steadiness good.

Instrument: Meade 8 inch, Super wide-angle, 18mm eyepiece; 36.2' fov

DSO Report N

Large, bright, round cluster covered in bid of haziness. A wide nucleus getting brighter. Resolved bright and faint stars spread out into fringy outliers. About 8 arc minutes in size.

(no date)

16-inch f/10 SCT (290x)

Large, bright and round globular with well resolved stars, could even be classified as an open cluster. Appears to be covered with a layer of haziness. Slowly brightening towards a very dense wide core. Busy star-field with a 6.9magnitude star about 6 arc minutes to the northwest. Resolved bright and faint stars spread out from the core into the rather irregular fringy edges and deep into the star-field. Somehow it has the look of a very dense open cluster. James Dunlop discovered this 8th magnitude globular cluster in Wales. Pretty large rather bright round nebula 3' Diameter very moderately condensed to the center resolvable into extremely minute stars, more scattered on the south side. Odd cluster appears very irregular to edges scruffy?

12-inch f/10 SCT (EP: 2-inch 40mm SW 76x 53' fov; 2-inch 32mm SW 95x 42' fov; 2-inch 14mm UW 218x 23' fov)

Large, bright and round globular with well resolved stars. Appears to be covered with a layer of haziness and slowly getting brighter towards a very dense wide core. Busy star-field with a 6.9 magnitude star about 6' arc minutes to the northwest. Resolved in bright and faint stars that spread out from the core into the rather irregular fringy edges and deep into the star-field (218x). Somehow it has the look of a very dense open cluster.

Location:Night Sky Caravan Park,Bonnievale.

Sky Conditions:Whole Milky is visible.The sky is clean.

Atmosphere stable with little interference.

Instrument:12-inch Dobsonian.

This globular cluster is seen as a mottled snowball which has a round halo of light and that the stars in this cluster is spherically concentrated towards each other.Around the outskirts of this cluster I have found bright chains of stars very clearly seen.The central core of this globular cluster is very bright compared to the stars on the outskirts of this cluster.There is a lot of condensation in this cluster.This globular cluster measures 9.2'*9.2'Chart:No.29,NSOG Vol.3.
