The asteroid on the outer edge of the main zone of 7354 Ishiguro (1995 BR1,1976 UE11,1982 VV4,1982 XN4) was photographed on the second night of the November 2021 work. When we photographed the fish spiral galaxy NGC 488, this came into the picture like several other asteroids. The asteroid was discovered by the Japanese amateur astronomer Takao Kobayashi at the Oizumi Observatory on January 27, 1995. The asteroid is named after Masato Ishiguro (b. 1945) of the Japanese ALMA project manager (Atacama Large Millimeter / submillimeter Array).

The size of the asteroid is 7.54km and the rotation speed is 6.224h / r. When photographed, the asteroid was 2,525au away and the closest October 19, 2021 2,447au.
