  6. BRAZILIAN SOLAR SPECTROSCOPE RECENT OBSERVATIONS • TOTAL OF ABOUT 1500 HOURS OF OBSERVATIONS • > 100 SOLAR FLARES OBSERVED HIGHLIGTHS: PATCH-LIKE EMISSIONS WITH DIFUSE TAILS DECIMETRIC HARMONIC ZEBRA EMISSIONS RAPID FREQUENCY OSCILATIONS DOTS WITH INTENSITY X FREQUENCY VARIATION FINE STRUCTURES (CHROMOSPHERIC EVAPORATION)

  7. BRAZILIAN SOLAR SPECTROSCOPE FLARE 06/06/00

  8. BRAZILIAN SOLAR SPECTROSCOPE PATCHES WITH DIFUSE TAIL PRE-FLARE FINE STRUCTURES

  9. RAPID FREQUENCY OSCILATIONS BRAZILIAN SOLAR SPECTROSCOPE

  10. BRAZILIAN SOLAR SPECTROSCOPE SPIKES AND DOTS

  11. BRAZILIAN SOLAR SPECTROSCOPE

  12. BRAZILIAN SOLAR SPECTROSCOPE TYPE III BURSTS

  13. BRAZILIAN SOLAR SPECTROSCOPE POTENCIAL DO BSS High resolution, high sensitivity and wide band will permit to investigate: • solar bustsassociated with impulsive phase of the flares and determination of: • exiceted and emitting agents • acceleration region • parameters of chromospheric evaporation • temporal fragmentation in the energy release • emission mechanism for FEs • multi-spectral investigations
