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. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

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 "Faint; oval. The 2nd of 6." and as "Round, suddenly brighter in the middle." These six are NGC 3576, 3579, 3581, 3582, 3584 and 3586.

Ellery, R.L.J. (1885) Melbourne Observations

Recorded in "Observations of the Southern Nebulae made with the Great Melbourne Telescope".

See the discussion of Lithograph M.4.35 for the details.

Notes: "Ced 113 A nebulous field discovered by John Herschel in 1834 and catalogued as follows. Ced 113 b = NGC 3579 = GC 2336 = h 3325. R. CPD -60 2626 = Potsdam spectral DM Area 193 No 48 may be the light-source."

Hoffleit, D. (1953)

1953AnHar.119...37H

A Preliminary Survey of Nebulosities and Associated B-Stars in Carina. p43.

Gum, C.S. (1955)

Gum, C.S. (1955) A survey of southern HII regions. Mem.RAS, 67. [1955MmRAS..67..155G]

A Survey of Southern H II Regions published in the RAS Memoirs, Vol. LXVII, identifies his No. 38a with this grouping. Gum 38b is NGC 3603, and he writes: "Two objects linked together with nebulosity (overall dimensions 45' x 15'). Each is of complex structure." For his 38a grouping, he gives the size as 20' x 15' and identifies the group with No. 113 in Sven Cederblad's 1946 catalogue.

Rodgers, Campbell & Whiteoak (1960)

The combined grouping of Gum 38a + b are also known as RCW 57, which is commented with "Appears obscuration-bounded and contains bright crescent shaped region 50' x 20'."

Sulentic & Tifft (1973)

(Sulentic and Tifft 1973) notes that this is a diffuse nebula.
