WIRCam Large Programs: First Call for Proposals.
The Canadian and French Agencies, through the CFHT Board of Directors (BoD), have indicated their willingness to make a significant fraction (25% to 50%) of their bright time available to large programs executed with WIRCam. WIRCam Large Program observations will be carried out as queue scheduled observations (QSO) starting with semester 2006A. Deadline for the first submission of such Large Programs will be August 24, 2005 at 24:00 UTC.

The webpage for WIRCam, CFHT's new Wide-Field instrument for the IR, is ready.
WIRCam has four 2048 x 2048 pixel HAWAII2-RG detectors, a 20 arcminute x 20 arcminute field-of-view and a sampling of 0.3 arcsecond per pixel. First light will take place in the first semester of 2005 and the instrument is offered for 2005B on a shared-risk basis.

The CFHTLS, with nearly 500 nights allocated over a five-year period, is a major commitment from the Canadian and French Agencies as well as a major scientific program for CFHT. To offer to the CFHTLS users an opportunity to share their experience with the CFHTLS data and their first scientific analysis, and to provide SAC with an opportunity to meet CFHTLS users, CFHT is organizing a workshop in Paris (IAP) just before the SAC meeting on May 26 and 27.

For its 25th anniversay, CFHT has released a spectacular image made up of tens of hours of telescope time spent on a single 1 degree by 1 degree field for the CFHT Legacy Survey (CFHTLS), one of CFHT's most ambitious scientific endeavors so far.
  • Sep. 13
ESPaDOnS's first light occurred around 10pm on the first engineering night, Sept. 2. These first 2 nights were very successful, and the instrument behaves very well. Consult CFHT's ESPaDOnS webpage for more details.

The 7th CFHT Users' Meeting, "The Canada-France-Hawaii Telescope in the Wide-field Imaging Era and Beyond", will be held at the Painter's Lodge, Campbell River (British Columbia), on 13-15 May 2004. Held approximately every three years, the Users' Meetings are intended to provide a forum for members of the CFHT astronomical communities to share their recent CFHT-based discoveries with their colleagues, learn about new facilities, and discuss future directions for the Observatory. It is anticipated that one day of the meeting will be devoted to early MegaPrime science, as well as an open discussion of the Legacy Survey. A second day of sessions will be devoted to other recent exciting CFHT science results, as well as presentations of the opportunities provided by the new facility instruments WIRCam and ESPaDOnS. The Saturday morning session will include a retrospective of CFHT's first 25 years and also provide an opportunity for an update on the future direction of the Observatory. Further information can be found on the meeting web site at:

A team of astronomers has discovered objects in a nearby galaxy group that may be small, young galaxies that have formed only recently. If confirmed, these objects would be among the nearest examples of small galaxies formed from gas expelled by a larger galaxy due to close encounters with other galaxies in the group. The astronomers reported their discovery at the American Astronomical Society meeting in Atlanta, Georgia. The observations were made with CFHT's now retired wide-field imager CFH12k, in QSO mode.

We are pleased to announce the first release of elixir data from the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS) to the CFHTLS community! The URL of the top page is for the english version and for the french version. 

The CFHTLS is a major imaging project aimed at solving some fundamental astrophysical questions in our understanding of planetary systems and the distant Universe. More than 450 nights of CFHT time will be devoted to the Survey over the next five years, using the MegaPrime imager. Details about the survey are available on the CFHTLS official webpage
