Solar Transients and Space Weather (STSW)

Overview

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.
