Thanks to the very good weather conditions in the last 2 months, we have been able to recover most of the delay accumulated during the fall. Almost all ``A'' proposals are now complete, with few exceptions. Most ``B'' proposals are nevertheless unlikely to be started, because of unfavourable combinations of frequency and LST range: 1.3 mm observations are difficult in daytime at this epoch of the year.
A ``blind'' adjustment of the panels from the inner ring of antenna 5
had been done late November. This adjustment could only be checked
when the interferometer was back to the compact D configuration late March.
The holography of antenna 5 performed late March yields a surface
accuracy of 50 
m. 3 out of 5 antennas now have a gain of
27 Jy/K at 245 GHz.
