The comet 2019U6 Lemmon had its maximum brightness of 6th magnitude in Jun 2020. However I could not capture the peak period of the comet due to bad weather. The comet in that day for my first observation positioned at 9 degrees west of epsilon Vir and had a 8th magnitude coma. The image shows that the comet has an undeveloped dust tail in southeast direction. We can chase the comet getting dimmer in evening west skies for a while.
