We discuss the implications of the first systematic observations of solar flares at
submillimeter wavelengths, defined here as observing wavelengths shorter than 3 mm …

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 …

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 …

Ground-and space-based observations of solar flares from radio wavelengths to gamma-
rays have produced considerable insights but raised several unsolved controversies. The …

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 …

We report on the study and successful application of an improved measurement method for
solar flares at millimeter wavelengths. A 210 GHz multibeam receiver for the observation of …

In this paper, we present a tutorial review which was presented at the first Advanced School
on Space Environment (ASSE 2004). We first describe the basics of radioastronomy …

The solar submillimeter-wave telescope (SST) is the only one of its kind dedicated to solar
continuous observations. Two radiometers at 0.740 mm (405 GHz), and four at 1.415 mm …

We present a report on the strong X5. 3 solar flare which occurred on 25 August 2001,
producing high-level γ-ray activity, nuclear lines and a dramatic long-duration white-light …

A new and unique solar submillimeter telescope (SST) was installed in the El Leoncito site,
Argentina Andes. It has a 1.5 m radomeenclosed cassegrain antenna, and arrays of four 212 …
