Boulder scientists’ work lead to astonishing images of sun’s surface

Thursday, February 6, 2020

The highest resolution images of the solar surface ever seen were made possible to no small degree by the work of Boulder based scientists. See article by Boulder's local newspaper, the Daily Camera.

ViSP Installation A Success! The HAO-built Visible Spectro-Polarimeter (ViSP) was successfully installed at the National Science Foundation (NSF) & National Solar Observatory DKIST over the course of five weeks during two visits by HAO scientists and engineers in December 2019 and January 2020. The ViSP measures the polarized light from the Sun, which allows scientists to measure the conditions of the solar plasma, including its magnetic field, temperature, and velocity. Polarized light is the key to understanding the physics of the Sun and improving our #2020SolarVision!

In this picture of the ViSP spectrograph system from the DKIST instrument room, P. Sekulic (NSO; left) and R. Casini (HAO-NCAR; right) are working on the three tunable spectral channels of the instrument. On the right we see the collimator system of the ViSP, consisting of the spectrograph slit station (in the foreground), the path-folding-mirror station, and the collimator lens. The diffraction grating, which distributes the light to the three spectral channels, and the three-mirror feed telescope, which forms an image of the Sun on the slit optic, are not visible in this photo.
