The Coronal Global Evolutionary Model: Using HMI Vector Magnetogram and Doppler Data to Determine Coronal Magnetic Field Evolution
J. Todd Hoeksema, William P. Abbett, David J. Bercik +10
The Coronal Global Evolutionary Model (CGEM) provides data-driven simulations of the magnetic field in the solar corona to better understand the build-up of magnetic energy that le…
Comparative Study of Data-driven Solar Coronal Field Models Using a Flux Emergence Simulation as a Ground-truth Data Set
Shin Toriumi, Shinsuke Takasao, Mark C. M. Cheung +4
For a better understanding of magnetic field in the solar corona and dynamic activities such as flares and coronal mass ejections, it is crucial to measure the time-evolving corona…
The Role of a Tiny Brightening in a Huge Geo-effective Solar Eruption Leading to the St Patrick's Day Storm
Yumi Bamba, Satoshi Inoue, Keiji Hayashi
The largest magnetic storm in solar cycle 24 was caused by a fast coronal mass ejection (CME) that was related to a small C9.1 flare that occurred on 15 March 2015 in solar active…
The Coronal Global Evolutionary Model: Using HMI Vector Magnetogram and Doppler Data to Model the Buildup of Free Magnetic Energy in the Solar Corona
George H. Fisher, William. P. Abbett, David J. Bercik +11
The most violent space weather events (eruptive solar flares and coronal mass ejections) are driven by the release of free magnetic energy stored in the solar corona. Energy can bu…
Statistical Analysis of the Horizontal Divergent Flow in Emerging Solar Active Regions
Shin Toriumi, Keiji Hayashi, Takaaki Yokoyama
Solar active regions (ARs) are thought to be formed by magnetic fields from the convection zone. Our flux emergence simulations revealed that a strong horizontal divergent flow (HD…
The Helioseismic and Magnetic Imager (HMI) Vector Magnetic Field Pipeline: Overview and Performance
J. Todd Hoeksema, Yang Liu, Keiji Hayashi +9
The Helioseismic and Magnetic Imager (HMI) began near-continuous full-disk solar measurements on 1 May 2010 from the Solar Dynamics Observatory (SDO). An automated processing pipel…
A Non-radial Eruption in a Quadrupolar Magnetic Configuration with a Coronal Null
Xudong Sun, Todd Hoeksema, Yang Liu +2
We report one of several homologous non-radial eruptions from NOAA active region (AR) 11158 that are strongly modulated by the local magnetic field as observed with the Solar Dynam…
Evolution of Magnetic Field and Energy in A Major Eruptive Active Region Based on SDO/HMI Observation
Xudong Sun, J. Todd Hoeksema, Yang Liu +4
We report the evolution of magnetic field and its energy in NOAA active region 11158 over 5 days based on a vector magnetogram series from the Helioseismic and Magnetic Imager (HMI…
HMI: First results
Rebecca Centeno, Steve Tomczyk, Juan Manuel Borrero +5
The Helioseismic and Magnetic Imager (HMI) has just started producing data that will help determine what the sources and mechanisms of variability in the Sun's interior are. The in…
