| Abstract: |
From 1919 to 2002, Paris-Meudon Observatory published synoptic maps of the Solar activity. Together with maps, tables were provided, containing some
information concerning at least filaments.
The board of Paris Observatory funded a data capture program concerning the 680 000
basic informations available in those tables.
On the other hand, in the frame of the FP7 European project HELIO, a Heliophysics
Feature Catalogue (HFC) has been developed, which contains also filaments data from
1996 up to now. We now pool all these data in order to give access to a filaments database for
nearly a century of observations. This allows to make statistical studies of those
Solar features, and try to correlate them with other information such as sunspot
number. We present here the data available for this long period of time. |
