Steve's Notes

===== NGC 1433 13.1" (2/18/04 - Costa Rica): fairly bright, large, oval 3:2 WNW-ESE, broad concentration with a large halo. The overall dimensions are ~3.5'x2.2'. I had a strong impression of extensions or the beginnings of two spiral arms (sketch made and verified); one arm begins at the west end and starts to curve towards the east on the south side while the other is symmetrically placed on the following end and hooks west on the north side. A mag 12 star lies 2.8' SW of center, beyond the halo. This barred spiral is the brightest member of the NGC 1433 group and part of the Dorado Cloud complex that includes NGC 1512, 1448, 1493 and 1411.
