7 Iris - 9.3.2022 at 20.00 Lahti Observation number 106211

Visibility II / V

Teemu Hämäläinen, Lahden Ursa

Ursa's Stars Yearbook had reported the appearance of the asteroid Iris during early spring. I followed the movement of the song four evenings at the turn of February and March. The composite image is composed of four stacked images, each with approximately one minute of exposure. At the last observation on 9.3, the asteroid's brightness had dimmed somewhat, and the rising moon hampered the observation with its brightness. The bright stars in the pictures are 45 and 51Geminorum.
