e-EVN: EA062B, RSY07, RP030E
A short-EVN observation of an unusual Seyfert galaxy 1ES 1927+654 (z=0.017), which is recently experiencing of dramatic optical (ASASSN-18el; ATel #11391) and X-ray (ATel #12169) outbursts and variabilities in magnitude and spectra, potentially supporting a turning on of a rapid accretion episode in the central engine. By comparing the proposed new data and archive data, we possibly witness a rare opportunity of a state transition in an active galactic nucleus (AGN). In this proposed observation, we intend to obtain its radio flux and pc-scale structures, and further investigate if there is a compact radio core, which is essential for future monitoring observations.
