Solar Submillimeter Telescope next generation
C. Guillermo Giménez de Castro, Jean-Pierre Raulin, Adriana Valio +3
The Solar Submillimeter Telescope (SST) is an unique instrument that has been observing the Sun daily since 2001 bringing a wealth of information and raising new questions about th…
A burst with double radio spectrum observed up to 212 GHz
C. G. Giménez de Castro, G. D. Cristiani, P. J. A. Simões +3
We study a solar flare that occurred on September 10, 2002, in active region NOAA 10105 starting around 14:52 UT and lasting approximately 5 minutes in the radio range. The event w…
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…
Submillimeter and X-ray observations of an X Class flare
C. G. Gimenez de Castro, G. Trottet, A. Silva-Valio +5
The GOES X1.5 class flare that occurred on August 30,2002 at 1327:30 UT is one of the few events detected so far at submillimeter wavelengths. We present a detailed analysis of thi…
Rapid pulsations in sub-THz solar bursts
Pierre Kaufmann, C. Guillermo Gimenez de Castro, Emilia Correia +3
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 p…
