NGC 5247 is a face-on unbarred spiral galaxy located some 60[3] million light years away in the constellation Virgo. It is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster.[4] This is a grand design spiral galaxy that displays no indications of distortion caused by interaction with other galaxies.[5] It has two spiral arms that bifurcate after wrapping halfway around the nucleus.[6] The disk is estimated to be 4.9 ± 2.0 kly (1.5 ± 0.6 kpc) in thickness and it is inclined by roughly 28° to the line of sight.[5]
Supernovae
[edit]Two supernovae have been observed in NGC 5247:
- PSN J13375721-1754272 (type II-P, mag. 15.6) was discovered by the Catalina Real-time Transient Survey on 24 July 2012.[7]
- SN 2016C (type IIP, mag. 15.7) was discovered by Masakatsu Aoki on 3 January 2016.[8]
