A gas-dynamic calculation of type 2 shock propagation through the corona [PDF]

An approximate analytic theory of acoustic shock propagation in nonuniform media is used to determine the motion of a flare-generated shock wave in the corona.

Estimating the Total Energy Content in Escaping Accelerated Solar Electron Beams

The Astrophysical Journal
Quantifying the energy content of accelerated electron beams during solar eruptive events is a key outstanding objective that must be constrained to refine particle acceleration models and understand the electron component of space weather.

Microwave Bright Points with Multiple Periodic Oscillations in the Solar Polar Coronal Hole during Solar Cycle Minimum

The Astrophysical Journal
During solar cycle minimum, polar coronal holes show a prominent radio brightening cap. The analysis of polar microwave enhanced radiation in polar coronal holes is helpful for understanding the magnetic field characteristics and the origin of the solar ...

Giant Postflare Loops in Active Regions with an Extremely Strong Coronal Magnetic Field

The Astrophysical Journal
We report for the first time the detection of thermal free–free emission from post-flare loops at 34 GHz in images from the Nobeyama Radioheliograph. We studied eight loops, seven of which were from regions with an extremely strong coronal magnetic field

8-CM RADIOHELIOGRAPH

8-CM RADIOHELIOGRAPH
An 8-cm radioheliograph which has been under construction since 1972 is almost completed. It has a maximum resolving power of 1.5 .arc min. and can be operated in various operational modes combined with the existing high-resolution compound interferometer. The minimum time necessary for taking a map is 40 seconds. A two-dimensional mapping will be used
