I. Endoh, National Astronomical Observatory of Japan, Tokyo, reports the<br>
discovery of a comet of magnitude 14.5 by Masayuki Iwamoto (Awa, Tokushima,<br>
Japan) on two 60-s CCD exposures obtained around Dec. 18.84 UT with a 10-cm<br>
f/4.0 Pentax SDUF II telephoto lens and a Canon EOS 6D camera. Iwamoto<br>
reported the approximate position as R.A. = 14h17m45s, Dec. = -24d44' (equinox<br>
J2000.0). S. Nakano, Sumoto, Japan, reports that the discovery images show a<br>
blue coma, and he provides the following astrometry that he measured from<br>
Iwamoto's images:<br>
