Pic Notes

NGC 5394 is a barred spiral galaxy located in the constellation Canes Venatici. Its speed relative to the cosmic microwave background is 3,639 ± 14 km/s, which corresponds to a Hubble distance of 53.7 ± 3.8 Mpc (~175 million ly). NGC 5394 was discovered by German-British astronomer William Herschel in 1787.

The luminosity class of NGC 5394 is II and it has a broad HI line. It also contains regions of ionized hydrogen. It is also a Luminous Infrared Galaxy (LIRG).

To date, one non-redshift-based measurement gives a distance of approximately 32,900 Mpc (~107 million ly). This value is far outside the Hubble distance values. Note that it is with the average value of independent measurements, when they exist, that the NASA/IPAC database calculates the diameter of a galaxy.

One supernova has been observed in NGC 5394: SN 2020aaxs (type Ib, mag. 17).

Arp 84
NGC 5394 and NGC 5395 are a pair of gravitationally interacting galaxies that appear in Halton Arp's Atlas of Peculiar Galaxies under the designation Arp 84. Arp noted that NGC 5495 is a spiral with a high surface luminosity companion at the end of one of its arms.

NGC 5395 group
According to A.M. Garcia, NGC 5394 is part of a group of galaxies that has at least five members, the NGC 5395 group. The other galaxies are NGC 5341, NGC 5351, NGC 5395 and UGC 8806.
