  In this dataset we provide a comprehensive collection of magnetograms (images
quantifying the strength of the magnetic field) 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 (regions of large
magnetic flux, generally the source of eruptive events) 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 is a
minimally processed, user configurable dataset of consistently sized images of
solar active regions that can serve as a benchmark dataset for solar flare
prediction research.
