Reduction of SOLIS/Vector Spectromagnetograph He I 1083 nm Observations

The SOLIS/Vector Spectromagnetograph (VSM) now continues the three- decade record of full-disk He I 1083 nm spectroheliograms from NSO/Kitt Peak (see poster by Henney et al.). Although the sensitivity of the VSM interim cameras at 1083 nm is far …

SOLIS-VSM Synoptic Products

Since August 2003, the Vector Spectromagnetograph (VSM) instrument has recorded full-disk photospheric and chromospheric magnetograms along with He I 1083 nm spectroheliograms daily as part of the Synoptic Optical Long-term Investigations of the Sun …

The Advanced Technology Solar Telescope -- Science Goals and Instrument Description.

High-resolution studies of the Sun's magnetic fields are needed for a better understanding of solar magnetic fields and the fundamental processes responsible for solar variability. The generation of magnetic fields through dynamo processes, the …
