The Virgo III Groups,[4]Virgo III Cloud,[5][1][6][3] or the Virgo-Libra Cloud[7][8][2] is a galaxy filament[3] consisting of at least 13 galaxy groups.[7][8] It is located approximately 87 Mly (27 Mpc) from the Solar System.[3]

The Virgo III Cloud, like the Leo Cloud,[1] is prolate and points toward the Virgo Cluster.[1][6]

List of groups

Below is a list of groups in the Virgo III Cloud according to astronomer Brent Tully.[7][8]

Column 1: The name of the group in Tully's NBGG[7][8]
Column 2: The right ascension for epoch 2000.
Column 3: The declination for epoch 2000.
Column 4: Number of members of the group.
Column 5: Brightest member of the group
Column 6: Redshift of the group.
Column 7: Distance of the group (Millions of light-years).
Column 8: Cross-Identifications with other catalogs.
