Corwin's Notes

===== NGC 2915 is a nearby "dwarf" (more properly, a "sub-giant") galaxy. Its face is nearly uniform on the IIIa-J blue DSS image, but there is an apparently eccentric nucleus seen on the IIIa-F image. All of the positions in the table refer to this nucleus. Courtney Seligman's image of it includes the tremendous neutral hydrogen disk that extends many diameters of the galaxy itself beyond the optical boundaries. It is a spectacular demonstration of the power of non-optical methods to show us previously unseen parts of the universe.

Steve's Notes

===== NGC 2915 24" (4/10/08 - Magellan Observatory, Australia): at 260x appears moderately bright and large, elongated 5:3 NW-SE, ~1.0'x0.6'. Appears slightly brighter at the NW end. An easy pair of mag 12-13 stars (25" separation) lies 4.5' NW. Located 8.4' NE of a mag 8 star. A very faint globular, E3, lies 43' SSW. This galaxy is classified as an unusual Blue Compact Dwarf. A significant percentage of its mass is within an extended neutral hydrogen halo that extends to nearly 20'x12' and within a massive halo of dark matter.
