Weather conditions and observations

We report excellent observing conditions up to mid January. High winds have somewhat reduced the observing efficiency, but today, as of January 31, we have observed 36 out of 46 A-rated and 31 B-rated programs, and already 7 have been classified as successfully completed.

As far as A-rated projects are concerned, we look forward to bring these to completion in the current winter semester. B-rated projects are likely to be observed only if they fall in a favorable LST range. We remind users of the Plateau de Bure interferometer that B-rated proposals which are not started before the end of the winter period have to be resubmitted again.

To optimize the observing efficiency with respect to the sun avoidance constraints of A-rated projects, the configuration schedule of the interferometer was slightly re-adjusted. The interferometer was moved to the most extended configuration (A) of the six element array at the end of December, and will move to the B configuration before mid February. We plan to move the array to the C configuration at the beginning of March, and finally switch to the most compact configuration (D) before the end of March. Global VLBI observations, which include the array in the 3mm phased-array mode, are planned from April 15 to 20, 2005. According to this plan, it will not be possible to complete projects requesting deep integrations and low-resolution mapping before the end of April.

Investigators, who wish to check the status of their project, may consult the interferometer schedule on the Web at http://www.iram.fr/IRAMFR/PDB/ongoing.html. The page is updated every day.
