A New Solar Burst Spectral Component Emitting Only in the Terahertz Range
Solar flare energy manifestations were believed to be the result of the same kind of particle acceleration. It is generally accepted that a population of relativistic electrons accelerated during theExpand

First detection of the impulsive and extended phases of a solar radio burst above 200 GHz
We present a detailed analysis of radio observations obtained at 212 and 405 GHz during the 2000 March 22 H α 2N flare that occured in AR8910 at ~1834 UT. These data are compared with microwave, softExpand

The effect of a total solar eclipse on long path VLF transmission
Abstract The effects of the total solar eclipse of 12 November 1966 on VLF transmissions at 26·1 kHz transmitted from NPM, Hawaii, and received at Sao Paulo, are presented. The eclipse occurredExpand

Large eddy simulation predictions of mixing enhancement for jets in cross-flows
The efficiency of a set of mixing enhancement devices on an array of jets in cross-flow is studied using large eddy simulation (LES). The baseline flow is a rectangular channel flow on which fiveExpand

Evidence that Synchrotron Emission from Nonthermal Electrons Produces the Increasing Submillimeter Spectral Component in Solar Flares
Abstract We investigate the origin of the increasing spectra observed at submillimeter wavelengths detected in the flare on 2 November 2003 starting at 17:17 UT. This flare, classified as an X8.3 andExpand

Analysis of daytime ionosphere behavior between 2004 and 2008 in Antarctica
Abstract In this paper we present 5-year study of the lower ionosphere behavior obtained from VLF sounding done at Comandante Ferraz Brazilian Antarctic Station. The results suggested a strongExpand

Sub-terahertz, Microwaves and High Energy Emissions During the 6 December 2006 Flare, at 18:40 UT
The presence of a solar burst spectral component with flux density increasing with frequency in the sub-terahertz range, spectrally separated from the well-known microwave spectral component, bringExpand

Solar flare detection sensitivity using the South America VLF Network (SAVNET)
[1] We present recent observations of Sudden Phase Anomalies due to subionospheric propagation anomalies produced by solar X-ray flares. We use the new South America VLF Network (SAVNET) to study 471Expand

RAPID PULSATIONS IN SUB-THz SOLAR BURSTS
A new solar burst emission spectral component has been found showing sub-THz fluxes increasing with frequency, spectrally separated from the well known microwave component. Rapid pulsations are foundExpand

A multibeam antenna for solar MM-wave burst observations with high spatial and temporal resolution
In this paper a new method for the determination of the position of microwave burst sources on the Sun, its implementation and first observational results, are presented. The 13.7 m antenna atExpand
