William Herschel has only one observation of this on 1 Feb 1786 where he says, "Diffused extremely faint nebulosity. The means of verifying this phenomenon are difficult." John Herschel and Dreyer took this to mean that the nebula was only suspected, so that is how it is entered in the GC and NGC.

William Herschel places the nebulosity 1 min, 26 sec east, and 7 arcmin south of Eta Ori. There is nothing here on either of the POSS1 plates, nor on the SERC EJ plate. However, 7 arcmin north of Eta Ori there is a very faint, very diffuse sheen of nebulosity (I make the approximate position 05 23.0, -02 20 for 1950). But could William Herschel have seen this? I very much doubt it. So, I've tentatively labeled this "Not found."
