1 Terahertz Flares H. S. Hudson SSL, UC Berkeley

2 SPD May 27, 2008 THz spectrum for solar studies Passbands at 0.2, 0.35, 0.67, 0.86 at best (driest) sites Early observations with bolometers Transparency fluctuations and solar variability => need to chop and/or have multiple feeds/panoramic detectors (up to 5 elements thus far)

3 SPD May 27, 2008 SST, El Leoncito (Argentina) Kaufmann et al. 2008

4 SPD May 27, 2008 SST, El Leoncito (Argentina) Kaufmann et al. 2008

5 SPD May 27, 2008 SST, El Leoncito (Argentina) Kaufmann et al. 2008

6 SPD May 27, 2008 Results and expectations THz component also observed at Gornergrat Physics is not understood. - Gyrosynchrotron radiation from highest energies - Kaufmann proposes coherent mechanism - Thermal processes in chromosphere Observations to date have been extremely primitive, but it is likely that many flares can be observed at THz
