Photometric Observations of Main-Belt Asteroids 784 Pickeringia, 1465 Autonoma, 1477 Bonsdorffia, 3057 Malaren, 5708 Melancholia, and 8548 Sumizihara

Photometric observations of selected asteroids were done from Znith Observatory, Flarestar Observatory (MPC-171), Luckystar Observatory (MPC-M55), and Manikata Observatory in 2023. The observations were made during a favorable apparition for each asteroid. Some of these targets were never studied in the past and thus their rotation periods were unknown.
