Corwin's Notes

===== NGC 2013 is probably a random scattering of about a dozen stars; it covers an area of about 11 arcmin by 6.5 arcmin if two stars south of the main group are included. JH called it simply "A poor cl of 8 or 10 sts 11 m", recording it in only one sweep. Most of the stars are east and south of his position, so the position I've estimated reflects that. Archinal and Hynes quote Brian's position -- though with a slightly larger RA -- and copy his comment, but have no other note on the object, aside from marking the cluster type with two question marks: "cl??". We should probably look at the proper motions and photometry of these few stars. Are they really part of a cluster, or are they -- as they appear to be -- simply a clump of field stars aligned along our line of sight?

Steve's Notes

===== NGC 2013 18" (11/6/04): This unimpressive asterism consists of two small groups of stars to the NW of mag 8.9 HD 37880. A group ~3' NW of the brighter star is a quartet containing two mag 10.5 stars, while 6' NW is a evenly distributed quintet of mag 11-12 stars. Also, a couple of arcminutes further NW are 3 stars including a double. The three small groupings are extended NW to SE and span 7', although John Herschel's description may just apply to the first two groups which are 4' diameter.
