Corwin's Notes

===== NGC 358. We've taken this as just the four stars near the d'A's position. Dreyer's summary description "Cl, vl Ri" seems appropriate, given d'Arrest's brief comment: Compluscularum stellarum congeries -- levissimi momenti. Capta cum inspicerem cumulum h. 83, qui ejusdem fere indolis. For those, like me, who don't know Latin, the web offers several translators. I tried a couple of them, and was finally able to come up with this: A cluster of several stars -- not many members. Found when observing the cluster h 83 [NGC 366], which is nearly of the same nature. With all due respect to d'A, NGC 366 is a much more populous and impressive cluster. However, I suppose it is possible that d'A was including more stars in the area in his own object. His position is about 1.2 arcmin north of the center of gravity of the four stars. However, I don't want to make too much of this, and will look to the visual observers for guidance beyond the asterism we've chosen. By the way, this probably is indeed an asterism. Given their lack of significant proper motions, the two eastern stars are well in the background, while the western stars have different proper motions from each other.

Steve's Notes

===== NGC 358 17.5" (11/6/93): consists of just four mag 11-12 stars in a 2'x1' trapezoid at the NGC position. This appears to be just a small asterism. 10' SE is also a scattered group in two detached sections elongated E-W with about a dozen mag 12-13.5 stars in each group.
