SOLIS Vector Spectromagnetograph: status and science
The Vector Spectromagnetograph (VSM) instrument has been recording
photospheric and chromospheric magnetograms daily since August 2003. Full-disk
photospheric vector magnetograms are observed at least weekly and, since
November 2006, area-scans of active regions daily. Quick-look vector magnetic
images, plus X3D and FITS formated files, are now publicly available daily. In
the near future, Milne-Eddington inversion parameter data will also be
available and a typical observing day will include three full-disk photospheric
vector magnetograms. Besides full-disk observations, the VSM is capable of high
temporal cadence area-scans of both the photosphere and chromosphere.
Carrington rotation and daily synoptic maps are also available from the
photospheric magnetograms and coronal hole estimate images.Comment: 4 pages, 2 figures, Solar Polarimetry Workshop 5, PAS
