Scientists Find Elusive Waves in Sun's Corona

The inclusion of LOS velocity measurements, along with intensity and linear polarization reveal ubiquitous propagating 3-5 mHz fluctuations in the solar corona, which have been identified as being predominately Alfvénic (Tomczyk et al. 2007).

University of Hawaii Solar-C 46 cm aperture coronagraph

Solar-C 46 cm aperture coronagraph at Haleakala records the intensity, and the linear and circular polarization (Stokes I,Q,U,V) of the forbidden lines of Fe XIII at 1074.7 nm.

COSMO Selects Refractor

The COSMO Technical Advisory Committee unanimously recommends that the project move forward with a 1.5 meter f/5 refracting design for the COSMO large coronagraph.
