PERIODIC COMET KOPFF (1970c)
     Dr. Elizabeth Roemer, Lunar and Planetary Laboratory, sends
the following precise positions, obtained using the Steward
Observatory's 229-cm reflector on Kitt Peak (cf. IAUC 2213).  The star
trails on the first plate are seriously affected by a flare at the
western end, presumably the effect of cirrus cloudiness, not a
focus change.  Measurer: Mrs. Barbara Schreur.
