Maintained by: Observatoire de Paris, France.

Summary of Data Held: Solar flares: observation reports and survey intervals from the Solar Flare Patrol Network (duplication of data from Boulder, Colorado). The observatory (not the WDC) holds the collection of spectro-heliograms used to derive the synoptic charts of the chromosphere since 1919.

User Services: Open to visitors, advance notice recommended. Databases for solar radio activity and spectroheliograms are under development.

Data Products, Publications, Catalogs: Evaluation of the flare events recorded by observatories, to establish a list of solar flares published in Quarterly Bulletinof Solar Activity and Solar Geophysical Data. Synoptic charts of solar flare positions and catalogs of flare activity for each active region published in Cartes Synoptiques de la Chromosphere Solaire, Observatoire de Paris.
