New striking aspects of solar activity have been found from observations at frequencies above 100 GHz, provided by the solar submillimeter-wave telescope (SST) at El Leoncito in the Argentina Andes. The SST utilizes a radome-enclosed 1.5-m Cassegrain reflector, operating simultaneously with four 212 GHz and two 405 GHz total power radiometers with 5ms time resolution. Partial overlapping of antenna beams at 212 GHz allow the spatial determination of burst transients as well as estimates of burst source upper limit sizes. Most probable attenuations at El Leoncito are of 0.2 and 0.9 Nepers, at 212 and 405 GHz respectively, along 310 days a year. A new solar burst spectral component has been discovered, exhibiting an intense impulsive bulk emi...
