      TOTAL SEARCHES FROM 1962 TO 1966 (5 years)         10894

Most members searched 10° x 10° areas with binoculars, usually to about
sixth magnitude.  During 1966, one member made numerous other searches.
Of the 2476 searches during 1966, David levy made 1271, or over half.

2.  OBSERVATIONS OF COMETS AND NOVAE, 1966.
       During the past year, the following observations were made of
comets:
                          Number      Number      Number
                          Observatns. Observers   Centres

Ikeya-Everhart, 1966d         1          1           1

The Coordinator of this section has not studied these observations yet,
but hopes to analse the Kilston reports in the near future.
       Mr. H.N.A. Maclean made two more observations of Nova Herculis, 1963
during 1966, and it appears to be near a steady 14th magnitude.

4.  OTHER INFORMATION, AND SUMMARY.
       One member (David Levy, Montreal) made telescopic searches for comets.
He searched for a total of 59 hours and 20 minutes during 1966.  As this
report was being prepared, five more 1966 observations of Comet Kilston
were reported, bringing the total to 62.
       Eight of the seventeen Centres were represented in this section in
one way or another, last year; either in searching or observing comets.
They were:  Montreal, Ottawa, Toronto, Hamilton, Niagara Falls, Windsor,
Quebec, and Victoria.  One unattached member took part.
       Of the many comet observations made last year, only a few gave detailed
reports.  Most gave little more detail than "I saw it."  Although even these
reports are welcome, the Coordinator would liek to receive more detailed
reportes so that a study could be made of them.  However, it is difficult to
encourage observer's to spend the time required to fill out duplicate
reports.  Possibly, if a comet observation report form were printed, it would
help.  The Coordinator of this section would like the opinion of the National
Chairmen and Committee.
        Although a record number of seraches were made during 1966, there has
been some falling-off in activity.  More than half of these searches were
made by only one member.  The high number of observations of Comet Kilston
are also largely responsible to another single member.  However, the Coordinator
hopes to stimulate interest among more members during 1967.
