Due to an issue on-board Swarm Bravo, the vector magnetic field data from the VFM instrument are not available from 10 April 2024 at 12:54 to 11 April 2024 at 10:27 (UTC time).

In addition, the anomaly on the VFM triggered a failure in both the FAST and OPER chains, resulting in the following gaps on the scalar magnetic field data from ASM instrument:

• from 10 April 2024 at 19:05 to 11 April 2024 at 10:27 (UTC time) for FAST data 
• from 11 April 2024 at 00:00 to 11 April 2024 at 10:27 (UTC time) for OPER data 

The ASM data gap on the operational production will be recovered soon, while due to the nature of the anomaly, the VFM data cannot be recovered.
