Zusammenfassung
Mingantu Spectral Radioheliograph (MUSER), is an aperture-synthesis imaging telescope, dedicated to observing the Sun, operating on multiple frequencies in the dm to cm range. MUSER is located in Mingantu Town, Inner Mongolia of China, about 400 km northwest of Beijing. MUSER is composed of two arrays of 40 4.5m antennas covering 400MHz -2 GHz, and 60 2m antennas covering 2 - 15 GHz including outdoor devices with antennas, LNBs, and indoor devices including receivers, correlators, etc. In the period of 2014-2019, about 94 solar radio burst events have been registered by MUSER. During the rising phase of the 25th solar cycle, MUSER also records some new events. The project to extend MUSER to the 40 - 400 MHz frequency regime with 224 log-periodic dipole antennas is under construction. The construction of a new 3-site Interplanetary Scintillation (IPS) telescope with the main site having three 140 m by 40m cylinder antennas at MUSER site and 2 sub-sites having 30 m parabolic antennas about 200 km apart has been approved and is under construction. All these are due to complete within a couple of years. We present the recent progress of the solar radio spectroscopy-imaging results from these facilities, including near-future developments and upgrades, as well as the progress of the IPS telescopes under construction in China. The MUSER and IPS telescopes at Mingantu Observing Station, National Space Science Center of the Chinese Academy of Sciences will play important role in solar and heliospheric physics.
