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…
Solar Wind Forecasting with Coronal Holes
S. Robbins, C. J. Henney, J. W. Harvey
An empirical model for forecasting solar wind speed related geomagnetic events is presented here. The model is based on the estimated location and size of solar coronal holes. This…
Automated Coronal Hole Detection using He I 1083 nm Spectroheliograms and Photospheric Magnetograms
C. J. Henney, J. W. Harvey
A method for automated coronal hole detection using He I 1083 nm spectroheliograms and photospheric magnetograms is presented here. The unique line formation of the helium line all…
SOLIS-VSM Solar Vector Magnetograms
C. J. Henney, C. U. Keller, J. W. Harvey
The Vector SpectroMagnetograph (VSM) instrument has recorded full-disk photospheric vector magnetograms weekly since August 2003 as part of the Synoptic Optical Long-term Investiga…
