Image Quality of SOLIS/VSM in Helium vs. Nitrogen
J. W. Harvey
The National Solar Observatory (NSO) Synoptic Optical Long-term Investigations of the Sun (SOLIS) Vector SpectroMagnetograph (VSM) is sealed and was designed to be filled with heli…
On the Polar Field Distribution as Observed by SOLIS
N. -E. Raouafi, J. W. Harvey, C. J. Henney
We use Vector Spectromagnetograph (VSM) chromospheric full-disk magnetograms, from the Synoptic Optical Long-term Investigations of the Sun (SOLIS) project, to study the distributi…
On the Latitude Distribution of the Polar Magnetic Flux as Observed by SOLIS-VSM
N. -E. Raouafi, J. W. Harvey, C. J. Henney
Magnetograms from the Vector SpectroMagnetograph (VSM) of the Synoptic Optical Long-term Investigations of the Sun (SOLIS) project are utilized to study the latitude distribution o…
SOLIS Vector Spectromagnetograph: status and science
C. J. Henney, C. U. Keller, J. W. Harvey +5
The Vector Spectromagnetograph (VSM) instrument has been recording photospheric and chromospheric magnetograms daily since August 2003. Full-disk photospheric vector magnetograms a…
Properties of solar polar coronal plumes constrained by Ultraviolet Coronagraph Spectrometer data
N. -E. Raouafi, J. W. Harvey, S. K. Solanki
We investigate the plasma dynamics (outflow speed and turbulence) inside polar plumes. We compare line profiles (mainly of \ion{O}{6}) observed by the UVCS instrument on SOHO at th…
Seething Horizontal Magnetic Fields in the Quiet Solar Photosphere
J. W. Harvey, D. Branston, C. J. Henney +3
The photospheric magnetic field outside of active regions and the network has a ubiquitous and dynamic line-of-sight component that strengthens from disk center to limb as expected…
