Solar Transients and Space Weather (STSW)

Overview

STSW Activities

STSW blends observation and numerical modeling efforts. STSW houses the HAO’s community leaders in the observation and theory of polarized radiation– "Spectro-polarimetry" (SP):

  • Perform fundamental radiative transfer theory,
  • Developing spectropolarimetric inversion techniques,
  • Maintained NSO/DST ASP and NSO/DST SPINOR instruments,
  • Developed, built and supported the Hinode/SP instrument.

Community Spectro-polarimetric Analysis Center (CSAC):

  • CSAC is our community connection,
  • Home of the Hinode/SP calibration/inversion pipeline,
  • Home to the SDO/HMI inversion routines,
  • CSAC will source CoMP SP inversions in the future.

Developing self-consistent numerical models of magnetic flux emergence and coronal mass ejection onset:

  • STSW is beginning an effort to develop an observationally driven model of nascent solar wind propagation for incorporation into global MHD simulation.

STSW is developing next-generation instrumentation for the measurement of magnetism throughout the solar atmosphere:

  • The Community Chromospheric Magnetometer (ChroMag),
  • Prominence Magnetometer (ProMag),
  • ATST/ViSP.

The STSW section has a deep pool of external collaborators.
