| Abstract: | The Vector Spectromagnetograph (VSM) instrument has been recording photospheric and chromospheric magnetograms 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 images 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. Recent science results, along with the status of the project and data products, will be summarized. Carrington rotation and daily synoptic maps are also available from the photospheric magnetograms and coronal hole estimate images. The SOLIS synoptic products are available on the NSO-SOLIS web site at: http://solis.nso.edu/. The VSM is part of the Synoptic Optical Long-term Investigations of the Sun (SOLIS) program. SOLIS VSM data used here are produced cooperatively by NSF/NSO and NASA/GSFC. The National Solar Observatory is operated by AURA, Inc. under a cooperative agreement with the National Science Foundation. |
