The Heliophysics Feature Catalogue, a tool for the study of solar features
Get PDFThe behavior of filaments and prominences during the Solar Cycle is a signature of Sun's activity. It is therefore important to follow their evolution during the cycle, in order to be able to associate it with the various phases of the Solar Cycle as well as with other Solar features or events. The virtual observatory HELIO provides information that can be used for such studies, especially its Heliophysics Feature Catalogue gives a unique access to the description of various features during around one cycle. Features available are: filaments, prominences, photospheric and coronal active regions, coronal radio emission, type III radio bursts, coronal holes and sunspots. Web interfaces allow the user to query data for these features. Useful information can also be shared with other HELIO services, such as Heliophysics Event Catalogue, which provides access to dozens of tables of events such as flares, CME

Retrospective Conversion of Solar Data Printed in "Synoptic Maps of the Solar Chromosphere": A Scientific and Librarianship Project
No full textInternational audienceBetween 1928 and 2003, the Observatoire de Paris published solar activity maps and their corresponding data tables, first in the Annals of the Meudon Observatory, then in the Synoptic Maps of the Solar Chromosphere. These maps represent the main solar structures in a single view and spread out on a complete Carrington rotation as well as tables of associated data, containing various information on these structures such as positions, length, morphological characteristics, and behavior. Since 2003, these maps and data tables have not been released in print, as they are only published on the online BASS2000 database, the solar database maintained by LESIA (Laboratory for space studies and astrophysical instruments). In order to make the first 80 years of observations which were available only in paper accessible and usable, the LESIA and the Library of the Observatory have started a project to digitize the publications, enter the data with the assistance of a specialized company, and then migrate the files obtained in BASS2000 and in the Heliophysics Features Catalog created in the framework of the European project HELIO
