“…The already mentioned first VLBI station in Africa, the 26 m radio telescope at the Hartebeesthoek Observatory in South Africa has began its life in 1961 as a NASA tracking station (Gaylard & Nicolson 2007). More recently, a former Soviet military 32 m antenna in Irbene, Latvia, has become a radio telescope involved, among other science applications, in VLBI observations as a member of the EVN (Upnere et al 2013). A 32 m satellite communication antenna at Warkworth in New Zealand has also become a radio telescope which, in particular, conducts LBA and global VLBI observations (Woodburn et al 2015).…”

Very Long Baseline Interferometry (VLBI) offers unrivalled resolution in studies of celestial radio sources. The subjects of interest of the current IAU Symposium, the Active Galactic Nuclei (AGN) of all types, constitute the major observing sample of modern VLBI networks. At present, the largest in the world in terms of the number of telescopes and geographical coverage is the European VLBI Network (EVN), which operates under the “open sky” policy via peer-reviewed observing proposals. Recent EVN observations cover a broad range of science themes from high-sensitivity monitoring of structural changes in inner AGN areas to observations of tidal eruptions in AGN cores and investigation of redshift-dependent properties of parsec-scale radio structures of AGN. All the topics above should be considered as potentially rewarding scientific activities of the prospective African VLBI Network (AVN), a natural “scientific ally” of EVN. This contribution briefly describe the status and near-term strategy for the AVN development as a southern extension of the EVN-AVN alliance and as an eventual bridge to the Square Kilometre Array (SKA) with its mid-frequency core in South Africa.
