NGC 2441

NGC 2441 is a barred spiral galaxy located in the northern constellation of Camelopardalis.^[2] Its velocity with respect to the cosmic microwave background is 3492 ± 2 km/s, which corresponds to a Hubble distance of 168.0 ± 11.8 Mly (51.51 ± 3.61 Mpc).^[3] In addition, 16 non-redshift measurements give a distance of 176.16 ± 16.80 Mly (54.012 ± 5.151 Mpc).^[4] The galaxy was discovered by German astronomer Wilhelm Tempel on 8 August 1882.^[5]

According to A.M. Garcia, NGC 2441 is a member of the NGC 2523 galaxy group (also known as LGG 154).^[6] This group contains five galaxies, including NGC 2523, NGC 2550A, UGC 4041, and UGC 4199.

One supernova has been observed in NGC 2441. SN1995E (type Ia, mag. 15)^[7] was discovered by Alessandro Gabrielcic on 20 February 1995, and observations suggested it may display a light echo, where light from the supernova is reflected from matter along our line of sight, making it appear to "echo" outwards from the source.^[2]
