This picture shows you two galaxies paralleling in north-south direction lying about 4 degrees NNW from tau Vir near a boundary on Bootes. An upper galaxy has a number of NGC5363 and lower one is NGC5364. NGC5363 is an elliptical galaxy without spiral structure with a diameter of 4 arc minutes. And NGC5364 is a spiral with proportioned and dimmed arms coiled up, has a size of about 7 arc minutes. Though both galaxies are minor with brightness of 11th magnitude, they're forming a small-scaled galactic group with surrounding small galaxies. A compact one just southwest of NGC5364 has a number of NGC5360.
