  The Vector SpectroMagnetograph (VSM) instrument has recorded full-disk
photospheric vector magnetograms weekly since August 2003 as part of the
Synoptic Optical Long-term Investigations of the Sun (SOLIS) project. After the
full deployment of the VSM data processing system, a typical observing day will
include three Fe I 630.2 nm full-disk photospheric vector magnetograms, one
full-disk photospheric and three Ca II 854.2 nm chromospheric longitudinal
magnetograms, along with three He I 1083 nm spectroheliograms. The photospheric
vector magnetograms will be available over the Internet in two stages: first,
as a quick-look product within minutes of data acquisition, and then as a
Milne-Eddington inversion product within a day of each observation.
