Camera Gap Removal in SOLIS/VSM Images
Andrew R. Marble, Lorraine Callahan, Alexei A. Pevtsov
The Vector Spectromagnetograph (VSM) instrument on the Synoptic Optical Longterm Investigations of the Sun (SOLIS) telescope is capable of obtaining spectropolarimetry for the full…
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…
Global Solar Free Magnetic Energy and Electric Current Density Distribution of Carrington Rotation 2124
Tilaye Tadesse, T. Wiegelmann, Pevtsov A Alexei +2
Solar eruptive phenomena, like flares and coronal mass ejections(CMEs) are governed by magnetic fields. To describe the structure of these phenomena one needs information on the ma…
First use of synoptic vector magnetograms for global nonlinear force free coronal magnetic field models
Tilaye Tadesse, T. Wiegelmann, S. Gosain +2
The magnetic field permeating the solar atmosphere is generally thought to provide the energy for much of the activity seen in the solar corona, such as flares, coronal mass ejecti…
Bimodal Distribution of Magnetic Fields and Areas of Sunspots
Andrey G. Tlatov, Alexei A. Pevtsov
We applied automatic identification of sunspot umbrae and penumbrae to daily observations from the Helioseismic Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO)…
Properties of Magnetic Neutral Line Gradients and Formation of Filaments
Nina V. Karachik, Alexei A. Pevtsov
We investigate gradient of magnetic field across neutral lines (NLs), and compare their properties for NLs with and without the chromospheric filaments. Our results show that there…
