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 solar flare driven by thermal conduction observed in mid-infrared
Fernando M. López, C. Guillermo Giménez de Castro, Cristina H. Mandrini +5
The mid-infrared (mid-IR) range has been mostly unexplored for the investigation of solar flares. It is only recently that new mid-IR flare observations have begun opening a new wi…
An MHD Study of Large-Amplitude Oscillations in Solar Filaments
Ernesto Zurbriggen, Mariana Cécere, María Valeria Sieyra +3
Quiescent filaments are usually affected by internal and/or external perturbations triggering oscillations of different kinds. In particular, external large-scale coronal waves can…
Formation of the thermal infrared continuum in solar flares
Paulo J. A. Simões, Graham S. Kerr, Lyndsay Fletcher +3
Observations of the Sun with the Atacama Large Millimeter Array have now started, and the thermal infrared will regularly be accessible from the NSF's Daniel K. Inouye Solar Telesc…
The 17 GHz active region number
C. L. Selhorst, J. E. R. Costa, C. G. Giménez de Castro +3
We report the statistics of the number of active regions (NAR) observed at 17 GHz with the Nobeyama Radioheliograph between 1992, near the maximum of cycle 22, and 2013, that also…
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…
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…
