A new solar situation awareness and flare forecasting dataset integrates 14 years of multi-source solar observations to support space weather monitoring and prediction research.
Integrating Multi-Source Solar Observations From 2010 to 2024
The core dataset compiles observations from the Helioseismic and Magnetic Imager (HMI) and the Atmospheric Imaging Assembly (AIA) aboard SDO. Researchers can utilize manually annotated segmentation masks covering major solar structures, specifically active regions, coronal holes, and filaments.
Extending Historical Coverage With SOHO Data
To extend historical coverage of solar magnetic and coronal observations further back in time, the dataset incorporates earlier data from the Solar and Heliospheric Observatory (SOHO).
All observations undergo spatial standardization. The data is mapped to a unified solar-disk coordinate system extending to 1.1 solar radii and resampled to ensure a consistent spatial scale across missions and instruments.

Frequently Asked Questions
What time span does the core solar dataset cover?
The core dataset spans a 14-year period from May 2010 to May 2024.
Which instruments provide the core space-based observations?
Observations are sourced from the Helioseismic and Magnetic Imager and the Atmospheric Imaging Assembly aboard the Solar Dynamics Observatory.
Does the dataset include historical records prior to 2010?
Yes, it incorporates earlier data from the Solar and Heliospheric Observatory, including MDI magnetograms from 1996 to 2010 and EIT extreme ultraviolet images.
What predictive data is included for space weather forecasting?
The archive features flare labels within a 24-hour prediction window, derived operational magnetic parameters, and manual mappings between SHARP patches and NOAA active region numbers.
