Active region magnetograms for solar flare prediction: Extra images dataset

In this dataset, we provide a comprehensive collection of magnetograms
from the National Aeronautics and Space Administration's
(NASA's) Solar Dynamics Observatory (SDO).  The dataset
incorporates data from three sources and provides SDO Helioseismic and
Magnetic Imager (HMI) magnetograms of solar active regions as well as
labels of corresponding flaring activity.  This dataset will be
useful for image analysis or solar physics research related to magnetic
structure, its evolution over time, and its relation to solar flares.
 The dataset will be of interest to those researchers
investigating automated solar flare prediction methods, including
supervised and unsupervised machine learning (classical and deep), binary
and multi-class classification, and regression.  This dataset
contains those images that were removed from the preconfigured datasets
(see usage notes below).
