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.

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. 5. BULLETINS AND ANNOUNCEMENTS: In 1966, two Bulletins and one Announcement were issued.

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.
