\section{Call for Observing Proposals on the 30m Telescope}

\subsection{Summary}
%
Proposals for three types of receivers will be considered for the
coming summer semester:

\begin{enumerate}
\item the observatory's  set of four dual polarization heterodyne
receivers centered at wavelengths of 3, 2, 1.3,  and 1.1 mm.
\item the 9 pixel dual-polarization heterodyne receiver array,
HERA, operating at 1.3 mm wavelength
\item 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.
\end{enumerate}

Emphasis will be put on observations at the longer wavelengths.
%summer/winter 
%, but 3mm proposals are also encouraged inasmuch
%as they are suited for medium or low quality weather backup onservations.
About 2100 hours of observing time will be available, considerably
less than in previous summer semesters (see below).

%which will allow
%scheduling of a few longer programmes ($\simlt 150$ hours).

The main news relevant for the coming summer semester are described
here. Details of proposal formalities, instrumentation, observing
modes, and estimation of observing time are described on the
\htmladdnormallink{IRAM web site.}{http://www.iram.fr/GENERAL/calls/s08/}




\subsection{What is new?}

The construction of the next generation heterodyne receivers for Pico
Veleta (NGPV) is progressing well. Based on a recent in--depth
evaluation, the installation is foreseen later this year.
The arrival of the NGPV receiver implies a profound
refurbishment of the Nasmyth cabin. Installation and commissioning 
of the NGPV receiver will take 4 weeks. The Nasmyth cabin optics and the other
receivers, HERA and the bolometers, are not affected at this stage.

%An effort was made with the NGPV receiver to keep as much as possible
%of the frequency range below 83 GHz. As the final outcome will not be
%known before the deadline, we recommend to interested astronomers to
%consider applying for these low frequencies now.  

An effort was made with the NGPV receiver to keep the scientifically
very interesting  frequency range below 83 GHz. Due to uncertainties
associated with local oscillator procurement, it is presently not
clear how much of this range can be made available when operation with
the NGPV receiver starts. We therefore recommend to astronomers to
propose urgent low frequency programs now.

The telescope's new control system is by now well worn in and
globally performs as well as the old control system. A host of new
features are planned to be introduced this summer (see  the
\htmladdnormallink{NCS web site}{/IRAMES/ncs30m}).

Remote observing is available from the IRAM offices in Granada and
Grenoble, and from the remote stations in Madrid and Bonn. A remote
station in Paris may also become available soon.
