Corwin's Notes

===== NGC 3103 = NGC 3100. Swift's position -- which is empty -- is roughly midway between NGC 3100 and NGC 3108, both found by JH. Swift notes a "coarse D* p"; it is actually following and a bit to the south of NGC 3100. Howe was the first to make this identification in one of his MN articles; Dreyer has the appropriate correction in the Notes to IC2. It is just possible that N3103 is actually NGC 3108. The RAs are exactly a minute of time different, and the declinations are within 0.1 arcmin. However, N3108 has a pretty bright star about 1 arcmin to the south that Swift probably would have mentioned (though JH didn't), and there are no double stars nearby, neither preceding nor following.
