Summary

Proposals for three types of receivers will be considered for the coming winter semester:

1. the observatory's set of four dual polarization heterodyne receivers centered at wavelengths of 3, 2, 1.3, and 1.1 mm.
2. the 9 pixel dual-polarization heterodyne receiver array, HERA, operating at 1.3 mm wavelength
3. The MAMBO-2 bolometer array with 117 pixels operating at 1.2 mm; the smaller MAMBO-1 array with 37 pixels is kept as a backup.

Emphasis will be put on observations at the shorter wavelengths. About 2800 hours of observing time will be available.

The main news relevant for the coming winter semester are described below. The details of proposal formalities, instrumentation, observing modes, and estimation of observing time are described on the IRAM web site.
