Overview

We invite proposals for the open-use observations of the East-Asian VLBI Network (EAVN). In 2018B semester, 9 telescopes participate in the EAVN open use, 7 telescopes of the KVN and VERA Array (KaVA) in Korea and Japan, Nobeyama 45-m telescope in Japan, and Tianma 65-mtelescope in China. Refer to the following EAVN website for more details about overview of the array and its performance, user support system, and how to prepare and submit a proposal(https://radio.kasi.re.kr/eavn/proposal_info.php)..

This open-use call is based on risk-share, and provides opportunities of VLBI observations at 22 and 43 GHz for astronomers in the world. A VLBI observation with single polarization (LHCP) and the data recording rate of 1 Gbps (total bandwidth of 256 MHz) is available in 2018B semester.

The total observation time for EAVN is up to 100 hours and observations will be scheduled between 1st September 2018 and 15th January 2019, while the available machine time and possible observation term for each telescope differ from each other. Refer to the EAVN Status Report, which can be downloaded via the EAVN webpage, for more details.

Target of Opportunity proposal
