Steve's Notes

===== NGC 1532 24" (12/1/16): SN 2016 iae, a type Ic supernova discovered on 7 Nov 2016, was observed 15" E and 52" N of center of NGC 1532, along the western edge of the spiral arm extending NNE. The major axis of the companion NGC 1531 off the west side, pointed exactly to an extremely faint "star". In poor seeing, the supernova was only occasionally visible, perhaps mag 15.5. 48" (10/22/11): this showpiece edge-on stretches 7'x1.2', tilting SW-NE. The galaxy is sharply concentrated with a large, elongated, very bright core that is mottled and increases to the center. The surface is knotty, streaky and mottled. A striking dust lane runs along the major axis, slicing the galaxy asymmetrically into two parts to the south of the core. The dust lane expands to a larger, elongated (dark) patch on the NE side of the core. The section to the south of the dust lane is much thinner and brightens to a prominent, very bright knotty 1.5' streak on the SW end [brightest part of a tidal tail extending towards NGC 1531]. A very faint star (B = 18.2) is close to the southwest tip of the bright streak. The fainter strip of galaxy south of the dust lane near the core appears patchy, probably due to dust and star-forming knots. Just northwest of the core is NGC 1531, a bright elliptical that angles perpendicular to the core and forms a striking pair. IC 2041 lies 7' NE of center, close following the NE tip of NGC 1532. It appeared fairly bright, fairly small, oval 3:2 NW-SE, ~35"x24", small bright core. 13.1" (12/22/84): bright, large, pretty edge-on 5:1 SW-NE, very bright nucleus, thin extensions. Forms a close pair with NGC 1531 1.6' NW.
