Named in honour of Richard A. F. Grieve, geologist with the Geological Survey of Canada and chief of their geophysical surveys. Grieve is a leading investigator of impact craters on the earth and moon. He maintains the global census of recognized terrestrial impact structures and has spearheaded the effort to obtain reliable ages for these structures. He also has been a leader in classifying the impacting bodies on the basis of siderophile element abundance patterns in impact melt rocks.

Named in honour of Michael R. Dence, executive director of the Royal Society of Canada and formerly a geologist with the Dominion Observatory. Dence was a pioneer in the geologic investigation of ancient impact craters on the Canadian shield. He made one of the first good estimates of the cratering rate on the earth in Phanerozoic time from studies of impact structures in Canada and Europe. JRASC

Named in honour of Clifford J. Cunningham (b. 1955-10), Canadian astronomer and writer, whose interest in minor planets has encompassed positional measurements and photometry. Cunningham's book "Introduction to Asteroids," published in 1988, has justifiably earned praise from both readers and reviewers. He has recently been working on a bibliographic database on minor planets that currently comprises more than 10,000 references dating back to the year 1789.

Orbit type: Mars-crosser

Named in honour of Sidney van den Bergh (b. 1929), Dutch-born Canadian astronomer, former director of the Dominion Astrophysical Observatory in Victoria, B.C. He was president of IAU commission 50 from 1985 to 1988 and a vice president of the IAU during 1976-1982.
Discovered by C. J. van Houten and I. van Houten-Groeneveld at Palomar.

Orbit type: Hilda

Named to commemorate the centenary of The Royal Astronomical Society of Canada. Incorporated in 1890 under the name The Astronomical and Physical Society of Toronto, the RASC received the Royal Charter¹ in March 1903. Its Journal has been published continuously since Volume 1 in 1907. The members of the Society have always included both professional and amateur astronomers.

Named in honour of Andrew Lowe, a Canadian professional geophysicist and amateur astronomer in Calgary who has particular interests in computational astronomy involving minor planets and occultations. In recent years, he has opened up a new area of identification research by establishing several cases of linkages of orbits where the observations of the minor planets involved were made on only two nights at individual oppositions.

Orbit type: Main Belt Asteroid

Named in honour of Cecil H. Green, co-founder of Texas Instruments and philanthropist extraordinary, to acknowledge a lifelong commitment to improve the quality of education and scientific research. Green and his late wife Ida funded educational and scientific projects throughout the world, such as academic buildings, health care centers, hospitals, libraries, scholarships and professorships.

Named in honour of Roy Dancey and Bruce D. Dancey, father and son, who successively headed the optical shop at the Dominion Astrophysical Observatory in Victoria from 1965 until 1986. Under their hands and direction, the primary and secondary mirrors for the 3.6-m Canada-France-Hawaii Telescope were figured and polished. They also produced new primary mirrors for the 1.8-m and 1.2-m telescopes at Victoria, as well as a host of smaller telescope optics, spectrograph optics and associated test optics.

Named in honour of Scott D. Tremaine (b. 1950). Tremaine has made seminal contributions to solar-system and galactic dynamics. He is co-author with James Binney of the leading monograph on galactic dynamics. Since 1985 Tremaine has been director of the Canadian Institute for Theoretic Astrophysics in Toronto, and the success of that organization owes much to his vision and leadership. Citation provided by P.M. Goldreich following a suggestion by the discoverer and A.W. Harris.

Orbit type: Main Belt Asteroid 

Named in honour of Matthew J. Holman (b. 1967- ), astronomer in the planetary sciences division at the Harvard-Smithsonian Center for Astrophysics. He is particularly known for his long-term investigations on the stability of the outer solar system by means of the sympletic integrator he co-developed, and he has studied the stability of planets around other stars. Recently, he has also become an active observer of centaurs and trans-neptunian objects.
