TL;DR: In this article, the Helioseismic and Magnetic Imager (HMI) active region patches (HARPs) are used to track the location and shape of magnetic regions throughout their lifetime.
Journal ArticleDOI
VFISV: Very Fast Inversion of the Stokes Vector for the Helioseismic and Magnetic Imager
J. M. Borrero,Steven Tomczyk,M. Kubo,Hector Socas-Navarro,Jesper Schou,Sebastien Couvidat,R. S. Bogart +6 more
TL;DR: In this paper, the authors describe the implementation and main properties of a new inversion code for the polarized radiative transfer equation (VFISV: Very Fast Inversion of the Stokes Vector).
Journal ArticleDOI
Solar Flare Prediction Using SDO/HMI Vector Magnetic Field Data with a Machine-learning Algorithm
TL;DR: In this article, a support vector machine (SVM) was used to forecast M-and X-class solar flares using four years of data from the Solar Dynamics Observatory's Helioseismic and Magnetic Imager.
Journal ArticleDOI
Comparison of Line-of-Sight Magnetograms Taken by the Solar Dynamics Observatory/Helioseismic and Magnetic Imager and Solar and Heliospheric Observatory/Michelson Doppler Imager
Yang Liu,J. T. Hoeksema,Philip H. Scherrer,Jesper Schou,Sebastien Couvidat,R. I. Bush,Thomas L. Duvall,Keiji Hayashi,Xudong Sun,Xuepu Zhao +9 more
TL;DR: In this paper, the authors compare line-of-sight magnetograms from the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO) and the Michelson Doppler Imager, onboard the SOHO.
