CORONAS-F Tracking
























SPIRIT

Full Sun XUV spectroscopy imaging

Institutes: LPI, IAS, SAI

Principal Investigators: Dr. I.A. Zhitnik


Scientific goals

  • Dynamics of active Sun from high resolution X and XUV spectral images in the 1,85-304 Å band
  • Dynamics of non-stationary solar events - flares, jets, CME in time scale from ~1 sec to months
  • Diagnostics of fine structure of solar plasma in flares, active regions, coronal holes with T = 0,05-50 MK
  • Study of Fe- and He-ions distribution in solar disk and corona up to 5 Rsun
