Corwin's Notes

===== "NGC 3557A" = NGC 3533. There is no problem with JH's position of NGC 3533, nor with de Vaucouleurs's for "NGC 3557A" as he called it in his Stromlo survey of southern Shapley-Ames galaxies. De Vaucouleurs simply missed the NGC entry for N3533.

Steve's Notes

===== NGC 3557 13.1" (2/17/04 - Costa Rica): fairly bright, fairly large, elongated 3:2 SSW-NNE, 2.5'x1.5'. Sharply concentrated with a prominent 40" core. With averted vision the diffuse outer halo extends to 3'x2' in size. A mag 10.5 star lies 3.3' SE. Brightest in a group (Klemola 18) including NGC 3564 7.7' E and NGC 3568 11.5' NE and part of the Hydra-Centaurus Supercluster. ESO 377-012, 20' WSW, appeared faint, moderately large, elongated roughly 2:1 NW-SE, 1.0'x0.5'. This galaxy has a very unusual appearance as a mag 12.8 star is superimposed and the galaxy appears as a faint, elongated, low surface brightness haze to the south of the star.
