S1-03 Data sets of historical observations of solar and geomagnetic activity

• Overview
• Over the past centuries, the solar and geoscience communities have accumulated a significant heritage of historical observations pertaining to past solar and geomagnetic activity. Those records contain irreplaceable information for studies of long-term changes in the sun and geomagnetic field. Unfortunately, most of those data are poorly organized and rarely accessible for modern scientific research.
• Discussions efforts
• Continued creation of a catalog of historical data from around the world
• Creation of a websites and Databases to provide easy access –
• Historicalsolardata.org
• Sunspot Index and Long-term Solar Observations database (SILSO for Historical sunspot observations)
• Develop plans to process data needed for specific community driven projects
• Data processing for Sunspot number ver. 3
• Develop plans for development of citizen science platform to help process historical records
• 'Sun Spot'ter: A citizen science environment for the extraction of Sunspot data from Sunspot drawings
• The need to create a classification system to help identify the datasets at highest risk of loss and flag them for priority preservation

​

​

Action Plan

• Continue identification of historical solar and geomagnetic data sources
• Create a metric to classify priority for preservation
• Continue work towards Sunspot Number ver. 3
• Release of Webpages and databases to action team members for testing and initial use
• After successful internal verification release the sites to public
• Initiate development of Sun Spot’er citizen science project
