[CEAmail] 2024-12-13 (13/12/2024)
December 09, 2024 : Station was decommissioned following the CEA's move.
December 13, 2024 : Missing data has been collected and integrated in the SONEL database. New Data available.
The New station will be installed in the first half of 2025 and will be named ALX3. More information in spring 2025.

[CEAmail] 2024-11-19 (21/11/2024)
We have not received the data since september 15, 2024.
November 19, 2024 : The CEA informs us that the station will be moved to them new office in december (no precise date). There is no date for the new installation.
Missing data (since september 15) will be accessible when the station shuts down
