Report of the EVN Scheduler to the CBD
             ======================================

1)         SESSIONS SCHEDULED SINCE THE LAST CBD MEETING


2005 Session 3:  Oct 18 - Nov 12

   Wavelengths: 6cm  1.3cm  18/21cm  90cm


As has become standard now, EVN stations all recorded on MK5A disks
for all projects, with some exceptions for global projects being
correlated at the VLBA correlator. The VLBA correlator can only take a
limited number of "external" MK5A recordings since it has only 9 MK5
playbacks. At least 4 of these are taken by 4 "disk-only" VLBA
stations and up to 8 VLBA stations can record disks (leaving only 1
slot for external stations). A maximum of 5 external stations could be
accomodated if 6 VLBA stations record on tape. For this session we
arrived at a compromise with only Tr, Nt, and On recording disks for
the VLBA correlator experiments, and Ar and Ro recording disks for the
small amounts of time when they were observing for them.

This session also contained one "UVLBI" project, which required
scheduling in 5 separate GST time slots on 3 different days, including
Ar and the GBT. Haystack Observatory provided equipment and logistical
support at the GBT and disks for Ar and GBT.

The nominal window for this session ended on 10 November but due to
GBT and Ar scheduling constraints it would not have been possible to
schedule the highest-rated 90cm project without extending the session
to 12 November at Wb, Jb and Ar. I thank these observatories for
permitting this. This resulted in a large gap between the end of the
18/21 cm part on 6 November, and the start of the 90 cm session on 11
November.


2)        SESSIONS IN 2006

The CBD agreed to the dates which I suggested at the last meeting for
sessions in 2006, and I have notified the VLBI community
accordingly. The dates are:

    2006  Session 1  Feb 16 - Mar 09

    2006  Session 2  Jun 01 - Jun 20

    2006  Session 3  Oct 19 - Nov 09

It is planned to have 5 and 6cm EVN+MERLIN in Session 1, together with
a few projects each at 18cm and 3.6cm.  It is also hoped to have a
30cm session in Session 2, so that some projects at this wavelength in
the backlog can finally be scheduled.




3)      SCHEDULING STATISTICS


In the course of preparing a contribution for the EVN Biennial Report
2003-2004 I inspected the lists of projects scheduled since I took
over as EVN Scheduler in 2002. I prepared a contribution for the EVN
Newsletter on scheduling statistics; I am sending a copy of this,
together with this report.
