The Next Plan of the Nobeyama Radioheliograph [PDF]
A high time- and spatial-resolution radio interferometer for solar observations has been constructed at Nobeyama (Figure I.; Nakajima et al. 1994). The Nobeyama Radioheliograph consists of 84 antennas, 0.8m in diameter, arranged on a T-shape lines of 500m in the EW and 220m in the NS directions.

Radioheliograph Observations of Microwave Bursts with Zebra Structures [PDF]
The so-called zebra structures in radio dynamic spectra, specifically their frequencies and frequency drifts of emission stripes, contain information on the plasma parameters in the coronal part of flare loops. This paper presents observations of zebra structures in a microwave range. Dynamic spectra were recorded by Chinese spectro-polarimeters in the

Microwave Perspective on Magnetic Breakout Eruption
Microwave maps may provide critical information on the flux rope interaction and the breakout eruption if their polarization is measured with high precision.

DIAGNOSTICS OF PLASMA JETS IN THE SOLAR CORONA
The paper discusses the diagnostics of plasma jets in the solar corona with the use of data from modern space- and ground-based telescopes observing the Sun in the extreme ultraviolet (EUV) and micro- wave bands.

CORONAL JETS AS A CAUSE OF MICROWAVE NEGATIVE BURSTS
We have investigated the cause of three “isolated” negative radio bursts recorded one after another at several frequencies in the 1–17 GHz range at the Nobeyama Radio Observatory, Ussuriysk Astrophysical Observatory, and Learmonth Solar Observatory on ...

Strongest Coronal Magnetic Fields in Solar Cycles 23 and 24: Probing, Statistics, and Implications
A strong coronal magnetic field, when present, manifests itself as bright microwave sources at high frequencies produced by the gyroresonant (GR) emission mechanism in thermal coronal plasma.
