The very faint nebula in the image may be ionised by the B 2.5V class star [F89b] S79 1. Other sources state that at least some of the visual emission in this direction may be associated with the supernova remnant SNR G49.2-0.7 (also called W51C
) which is believed to be at a distance of 6 kpc.
Avedisova combines Sh 2-79 and W51C in the star formation region SFR 48.96-0.55
along with four infrared sources.
