	Canadians celebrate 'Science Success Story' on a Hawaiian Mountain Top - National Research Council Canada
		The CFHT, located on the barren and frigid 4200-metre summit of Mauna Kea, is celebrating over two decades of scientific discovery and technological innovation.
		It is marking its 21st birthday with events that include an open house, lectures and scientific meetings that celebrate the past, present, and future of a scientific facility that, a recent study has shown, has been the most scientifically productive 4 metre telescope in the world.
		The CFHT, which is a collaboration of Canada, France and the University of Hawaii, was the first large telescope to be constructed on Mauna Kea.

		University of Hawaii -- The Canada-France-Hawaii Telescope (CFHT) is one of the oldest facilities on the summit of Mauna-Kea.
		The result of a fruitful collaboration between CFHT and institutes in France and Canada, MegaPrime is a completely new structure installed on top of the telescope, equipped with specially designed optics and a unique made-in-France digital camera of 340 megapixels called MegaCam.
		It will be possible to look for small objects moving around planets, or the outskirts of the solar system; astronomers will be able to watch the explosions of dying stars in remote galaxies, study the ripples of space due to unseen matter, or witness new and mysterious phenomena yet to be discovered.

		The scientists and the institutes involved in the MEGACAM project are L. Vigroux from the Commisariat a l'Energie Atomique (Saclay, France), D. Crampton from the DAO, Y. Mellier from the Observatoire Midi-Pyrenees (Toulouse, France) and Nick Kaiser from CITA.

	Competitive Site and Timescale: An 8m CFHT
		The first choice to achieve our scientific goals of a wide field 8m telescope is to work within the existing CFHT partnership, roughly along the lines of the plans recently prepared by J. Espiard and W.
		The CFHT partners have been vigorously yet carefully examining the Telescope's future in the near- and long-terms through the Scientific Advisory Committee (SAC), the Next Generation CFHT Committee, the Board, as well as through national committees and planning exercises.
		But no scientific case can be made that it would be undesirable to replace the aging CFHT 3.6 m as soon as possible with a modern 8m instrument, with some twelve months of down-time.

		The CFHT now has a "minimum time" policy; ie., an instrument must remain on the telescope at least 4 nights, otherwise it will not be scheduled.
		A CFHT proposal has the reputation of having one of the toughest scientific justifications to write in all of astronomy.
		Indeed, one often hears from cynics that a CFHT scientific justification (hereafter SJ) is essentially a journal paper with blanks for the observational results.

		This is a very complex issue because, at its essence, it involves matters related to Hawaiian Sovereignty and control of "ceded lands" (land which formerly belonged to the Kingdom of Hawaii that passed to the Territory and then to the State of Hawaii).
		Advantages of moving CFHT more aggressively toward a WF-IR capability include the fact that there is still considerable room for the development of IR arrays and mosaic-cameras.
		With a truly wide-field IR camera, the scientific life of CFHT as an independent, front-line research facility could be extended beyond the end of the next decade.

	CNRS - 25 candles for the Canada-France-Hawaii Telescope
		On September 28, 1979, the Canada-France-Hawaii telescope (CFHT) was inaugurated on one of the best observation sites in the Northern hemisphere, atop Mauna Kea, a 4,200-meter high volcano on the island of Hawaii (United States).
		The sixth largest optical telescope in the world, with a diameter of 3.60 meters, the CFHT was the result of a tripartite agreement entered into four years earlier by Canada's National Research Council (CNRC), the French National Center for Scientific Research (CNRS) and the University of Hawaii.
		By contrast, the CFHT was designed from the outset to obtain a very large circular visual field with a diameter of nearly one degree, which is twice the apparent diameter of the full moon in the sky.

	THE CFHT IMAGING SURVEY OF BL LACERTAE OBJECTS II:
		The results of an extensive imaging survey of BL Lac Objects conducted at the CanadaFranceHawaii 3.6m Telescope (CFHT) are presented.
		This paper details the results pertinent to the clustering environments of BL Lacs; a companion paper (Wurtz, Stocke and Yee 1996; Paper 1) presented results on the host galaxies of BL Lacs obtained from the same Gunn r-band images.
		Since X-ray observations find rapid cosmic evolution in the intracluster medium and cluster postential well over similar timescales, the rapidly changing gas density and/or galaxy-galaxy interaction rate could be responsible for the rading of luminous AGNs in rich clusters (Stocke and Perrenod; Roos).

		Bottom Line the CFHT Airmass Coeff's - The slope of the data in the airmass versus fluxscale plots agrees with the expected slope using the CFHT canonical value.
		This trend can then be compared to the canonical CFHT airmass coefficient for the given filter to verify the correctness of the value.
		A first attempt at this revealed a significant scatter in the offsets from sequence to sequence and revealed sequences that were clearly non-photometric, departing from the slope indicated by the canonical airmass coefficient.

		Following GCN #829 by Halpern et al., a more accurate reduction of the CFHT data has been made, with the problems encountered when none of the observations is made in photometric reduction.
		The 5 nights of observations at CFHT lead to a decay slope of 2.16 +/- 0.03 but it's not really possible to link accurately the CFHT magnitudes to others as long as there is no calibration of the field stars made.

	ESA Science & Technology: Titan's surface From CFHT
		Narrow band images were obtained first at wavelengths sensitive mostly to the emission from Titan's atmosphere (1.18 microns J2, 1.64 microns H2), then in bands where both atmospheric and surface emissions contribute (1.29 microns J1, 1.6 microns H1).
		The presence of such a compound in equatorial regions could be related to the presence of a high mountain range.
		The images were obtained with PUEO at the CFHT in 1997 and 1998, the latter during excellent seeing conditions (with peaks at 0.3 arcsec in the visible).

		Early observations conducted during the installation phase have already demonstrated the power of this new instrument: many previously unknown moons of Jupiter have been discovered, potentially hazardous asteroids that pass near to the Earth have been studied, and wide areas of the sky have been surveyed to prepare targets for a future space mission.
		MegaPrime is a collaboration between several research institutes in France, and NRC's Herzberg Institute of Astrophysics (HIA) in Victoria, B.C. Several major industrial contractors participated in building the large optical and mechanical components of this device, which is mounted at the prime focus of the CFHT.
		The huge number of pixels means that the images are obtained at very high resolution, allowing astronomers to zoom in and separate individual stars in crowded star fields, and to see the detailed structure of faint, distant galaxies.
