Swarm Alpha: EFI LP and LPI data gap on 18 December 2018

02 January 2019

Electric Field Instrument (EFI) LP and LPI data measured by Swarm Alpha are not available on 18 December 2018. The reason for this data gap is still under investigation.

Swarm Alpha: VFM data gap from 18 to 19 December 2018

02 January 2019

Due to a science packet corruption which occurred on the VFM (Vector Field Magnetometer) on board Swarm Alpha, the VFM science data (at 50 Hz rate) were not received from 18 December 2018 at around 18:13 UTC to 19 December 2018 at 16:46 UTC when the VFM was restarted. As a consequence, no L1B VFM data are available for this time window.

Swarm Bravo: Gap in EFI data from 16 to 17 October 2018

19 December 2018

We inform the Swarm users that an issue was registered on-board Swarm Bravo during the EFI-TII Gain Correction Map application. This issue caused a data gap in EFI data from 16 October 2018 13:33:57 UTC to 17 October 2018 08:28:17 UTC

Swarm Alpha VFM issue from 29 April to 01 May 2017: data regenerated

20 November 2018

Swarm Bravo VFM issue from 11 to 13 September 2017: data generated

20 November 2018

With reference to the news published on 14 September 2017, we inform the Swarm users that the Swarm Bravo MAGx_LR_1B data from 11 to 13 September 2017 have been generated and now can be found in the ESA FTP server.

Swarm Charlie STR issue from 07 to 25 May 2018: data regenerated

20 November 2018

With reference to the news published on 29 May 2018, we inform the Swarm users that the issue present in the STR data, caused by 1-pixel shift in STR CHU-3, has been fixed. All the Swarm Charlie Magnetic data from 07 to 25 May 2018 have been regenerated and now can be found in the ESA FTP server.

Extension of Swarm 2 Hz TII Cross-Track data flow dataset

Swarm Alpha: ACC data gap from 16 to 17 October 2018

22 October 2018

Swarm Bravo: VFM data gap from 19 to 27 August 2018

29 August 2018

Due to a science packet corruption which occurred on the VFM (Vector Field Magnetometer) on board Swarm Bravo, the VFM science data (at 50 Hz rate) were not received from approximately 10:00 UTC on 19 August to 07:10 UTC on 27 August 2018 when the VFM was restarted.

Swarm Charlie: Gap in EFI data on 07 August 2018

16 August 2018

A gap in data acquired by the Electric Field Instrument (EFI) on the Swarm Charlie spacecraft occurred on 07 August 2018. The duration of this gap was from 14:46:31 to 14:53:12 UTC and was due to a gain map update.

Swarm Alpha: L1B ASM data gap from 24 to 26 July 2018

06 August 2018

Due to a test performed on the ASM (Absolute Scalar Magnetometer) commanded in burst mode on board Swarm Alpha, the magnetic field intensity derived from the ASM in the MAGA_LR_1B and MAGA_CA_1B products is set to zero from 24 July 2018 at 14:44 UTC to 26 July 2018 at 07:00 UTC.

Unexpected Swarm A GPS receiver reboot on 26 July 2018

31 July 2018

The Swarm A GPS receiver rebooted on 26 July 2018 at 05:07:02 UTC autonomously. The GPS receiver data and time synchronization were available again at 05:29:47 UTC. The satellite's orbit and attitude seem unaffected by the anomaly. While the investigation is ongoing, it seems that there is no impact on the good health of the GPS receiver.
