THE FIRST ASTRONOMICAL TEST OBSERVATIONS OF THE VIRAC RT-32
For a more detailed information on the first astronomical test observations with the VIRAC 32 metre radiotelescope, see Ozolins et al. 1998 (in Latvian Journal of Physical and Technical Sciences, 1998, N6). See also the chronology of events.

Radio observations of the solar eclipse on August 11, 1999
We have started with a hope to explore the unique possibility of the solar eclipse to achive the angular resolution of a few arc seconds with the 32-meter radiotelescope.

The RT-32 is designed to make observations as a single-aperture antenna as well as a part of interferometer network.
After a set of the test astronomical observations with the 32 meter radio telescope the solar and low-frequency VLBI observations lie ahead. Both the radio mapping of the Sun and the tracking of the alone standing solar active regions are scheduled. The goal is to improve our understanding of a solar flare and the evolution of the large-scale coronal structures, such as coronal holes.
It is suggested to participate the Low Frequency VLBI Network which main directions of research are:
The host as well as
join projects for solar observations with the VIRAC RT-32 are welcome.
