Automatic Active-Region Identification and Azimuth Disambiguation of the SOLIS/VSM Full-Disk Vector Magnetograms
M. K. Georgoulis, N. -E. Raouafi, C. J Henney
The Vector Spectromagnetograph (VSM) of the NSO's Synoptic Optical Long-Term Investigations of the Sun (SOLIS) facility is now operational and obtains the first-ever vector magneti…
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…
Magnetically Preferred Solar Longitudes: Reality?
C. J. Henney, B. R. Durney
The observed persistence of specific periodicities detected in time series associated with solar surface magnetic activity over several solar cycles has led to numerous papers supp…
