Abstract
Ventspils International Radio Astronomy Centre (VIRAC, Latvia) operates two radio telescopes RT-16 and RT-32 accordingly with 16 and 32 m fully steerable Cassegrain type antennas. The main receiving systems of the both telescopes are cryogenic receivers with 4.5 – 8.8 GHz frequency range; additionally, in 2019 radio telescope RT-32 will be equipped with new L band receiver. Data registration units of the both antennas are suitable for interferometric observations. The Nicolaus Copernicus University Department of Radio Astronomy in Torun, Poland, operates 32 m radio telescope RT-4, which also works in similar bands - L, C and M - and regularly participates in the VLBI observations. Also VIRAC has a high performance computer cluster with SFXC software correlator developed at JIVE.
In the spring 2018 VIRAC team with support from Torun group conducted several VLBI experiments in the baseline Irbene - Torun using Irbene radio telescope RT-16 and Torun RT-4. Successful fringes and FITS files with uv data obtained mean, that data correlation and post processing facilities established in VIRAC allow to run small scale interferometric tasks.
