This is the assembly of 60 30-seconds CCD pictures of the comet taken between 18h56m UT and 19h30m UT of January 23rd 1998. Sposetti used a Celestron 20cm f:6.3 telescope and an Hi-SIS22 CCD camera, in 2x2 binning mode. North is up ,East is left. The comet was moving very fast from North to South in the Perseus constellation. The final image spans 7.7 x 5.2 arcminutes. No additional filters were used. The comet was 1.13 AU from the Sun and 0.43 AU from Earth.
