A bright impulsive solar burst detected at 30 THz
P. Kaufmann, S. M. White, S. L. Freeland +11
Ground- and space-based observations of solar flares from radio wavelengths to gamma-rays have produced considerable insights but raised several unsolved controversies. The last un…
Terahertz photometer to observe solar flares in continuum
Rogerio Marcon, Pierre Kaufmann, Luis Olavo T. Fernandes +6
Solar observations at sub-THz frequencies detected a new flare spectral component peaking in the THz range, simultaneously with the well known microwaves component, bringing challe…
Sub-THz and Hα activity during the preflare and main phases of a GOES class M2 event
Pierre Kaufmann, Rogério Marcon, C. Guillermo Giménez de Castro +8
Radio and optical observations of the evolution of flare-associated phenomena have shown an initial and rapid burst at 0.4 THz only followed subsequently by a localized chromospher…
Fast Mid-IR Flashes Detected During Small Solar X-Ray Bursts
Marta M. Cassiano, Pierre Kaufmann, Rogerio Marcon +6
Solar observations in the mid-infrared 8-14 μ\m band continuum were carried out with cadence of 5 frames per second, in December 2007. Rapid small heated sources, with typical dura…
