The comet Hale-Bopp in that day has a brightness of 6.5th magnitude and a heliocentric distance of 4 a. u. (about 600 million km), just entered inside of the Jupiter's orbit. Normal comets cannot be detected with amateur's scopes, but in that day I could observe the comet easily with a portable binocular. I was aware that the comet Hale-Bopp was a great comet of the century. Additionally, the comet had a coma with about 10 arc minutes in diameter; I could detect the clockwise spiral structure through a telescope.
