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

NGC 1333. Though there is no question about the identity of this nebula, its early observations with small telescopes were contradictory enough to lead to suggestions that it might be variable. The note in Auwers's 1862 appendix to WH's catalogue makes it clear that Tuttle's observation of 1859 has the directions of the field inverted. This probably contributed to the perception of variability.

Interestingly, part of the object seems to be a collapsing protostar (see Sky and Telescope, January 1997, pages 15 and 16 for the story). Is it thus possible that N1333 really is variable? Depending on the density, position, and orientation of dust clouds around the protostar, and the possibly changing intensity of the star itself, variability from our point of view is not out of the question. This is apparently the cause of the variability of the nebulae around T Tauri (NGC 1554 and NGC 1555, which see), and perhaps also explains the variability of NGC 2261 (also which see).

Historical observations

NGC/IC Dreyer (1888, 1895, 1908)

Recorded by Schonfeld from Mannheim, Germany, as faint, large with a 10th magnitude star north following. Dreyer notes that "the brightness has been suspected to vary, but it is probably a case like the Merope nebula."

Modern observations

Rajanen, Petteri (1992)

(Kauppi, Tampere, Finland) observing with a 8-inch f/5, writes in The Webb Society Nebulae and Clusters Section Report No. 10, July 1992: "Best seen with no filter. At x38 looks fuzzy and shape very vague. Uniform surface brightness. most of the nebula lies to the S of a mag 9.5 star."

Tom Lorenzin

Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "9'x 5' extent; large and faint reflection nebula with 9M star on N edge; situated in large DK NEB B-205"

Steve Gottlieb

03 29.3 +31 25

17.5: fairly bright reflection nebula surrounds a mag 10 star which is offset to the NE side of the nebula. This is a large object, about 10'x6' and elongated SW-NE. There is a bright knot in the SW end. Two or three 15th magnitude stars are superimposed.

13: fairly bright nebula, large, extends SSW of a mag 9.5 star, oval, slightly brighter at the S edge.
