NGC 5668
As seen from the Earth, it is inclined by an angle of 18° to the line of sight along a position angle of 145°. The morphological classification in the De Vaucouleurs system is SA(s)d, indicating a pure spiral structure with loosely wound arms. However, optical images of the galaxy indicate the presence of a weak bar structure spanning an angle of 12″ across the nucleus. There is a dwarf galaxy located around 650×10 ly (200 kpc) to the southeast of NGC 5668, and the two may be gravitationally interacting.
Three supernovae have been observed in this galaxy: SN 1952G (type unknown, mag. 17.9), SN 1954B (type Ia, mag. 12.3), and SN 2004G (type II, mag. 17.2). The last was initially imaged on January 19, 2004, at 43" to the west and 12".5 south of the galaxy core. High velocity clouds of neutral hydrogen have been observed in NGC 5668, which may have their origin in supernova explosions and strong stellar winds.
