A Compact Full-disk Solar Magnetograph based on miniaturization of GONG instrument
Sanjay Gosain, Jack Harvey, Valentin Martinez-Pillet +2
Designing compact instruments is the key for the scientific exploration by smaller spacecrafts such as cubesats or by deep space missions. Such missions require compact instrument…
Magnetograph Saturation and the Open Flux Problem
Y. -M. Wang, R. K. Ulrich, J. W. Harvey
Extrapolations of line-of-sight photospheric field measurements predict radial interplanetary magnetic field (IMF) strengths that are factors of ~2--4 too low. To address this "ope…
Zeemanfit: Use and Development of the solis_vms_zeemanfit code
Anna L. H. Hughes, Jack Harvey, Andrew R. Marble +1
The purpose of the SOLIS Zeemanfit Code is to provide a straight-forward, easily checked measure of the total magnetic-field strength in the high-strength umbral regions of the sol…
Comparison of Ground- and Space-based Longitudinal Magnetograms
A. Pietarila, L. Bertello, J. W. Harvey +1
We compare photospheric line-of-sight magnetograms from the Synoptic Long-term Investigations of the Sun (SOLIS) vector spectromagnetograph (VSM) instrument with observations from…
Improvements in the determination of ISS Ca II K parameters
Luca Bertello, Alexei A. Pevtsov, Jack W. Harvey +1
Measurements of the ionized Ca II K line are one of the major resources for long-term studies of solar and stellar activity. They also play a critical role in many studies related…
