This dataset is intended to be used for training/testing solar flare forecasting models. It contains various data splits (in json format) of SDO/HMI magnetogram images compiled by 
`Boucheron, L.E., et al., 2023, Sci Data 10, 825, https://doi.org/10.1038/s41597-023-02628-8`. 

Splits "train", "val", "test" corresponds to the original data splits provided by Boucheron et al., while the other splits are created by downsampling the No-Flare and C flare class to obtain
more balanced splits and mitigate class imbalance.
