NGC 5364 (NGC 5317, UGC 8853, PGC 49555 and others) is a grand design spiral galaxy located approximately 51 million light-years away (https://www.aanda.org/articles/aa/pdf/2019/11/aa34553-18.pdf) in Virgo.
NGC 5363 (UGC 8847, PGC 49547 and others) is the elliptical above NGC 5364. Several sources mentioned it might be interacting with 5364 but the same paper referenced above finds this one approximately 183.4 million light-years away.
Abell 1809 is the cluster of galaxies near the center on the right side.
