Swarm Bravo: Partial missing Science data on 31 January 2019

11 February 2019

We inform the Swarm users that on 31 January 2019 at 15:22 UTC, Swarm B experienced a SEFI (Single Event Functional Interrupt) event. As a consequence, the dump of this packet store was aborted autonomously.

Swarm helps pinpoint new magnetic north for smartphones

08 February 2019

Since it was first measured in 1831, we have known that the magnetic north is constantly on the move. However, its tendency to slowly roam has stepped up a pace recently – so much so that the World Magnetic Model has had to be updated urgently with the pole's new location, vital for navigation on smartphones, for example. ESA's magnetic field Swarm mission has been key for this update.

Swarm Bravo: L1B and L2 Cat-2 data gap from 19 to 28 August 2018 recovered

04 February 2019

With reference to the news published on 29 August 2018, we inform the Swarm users that the Swarm Bravo magnetic field data from 19 to 28 August 2018 have been generated and now can be found in the ESA ftp server.

Swarm Bravo: L1B ASM data gap from 21 to 28 January 2019

29 January 2019

We inform the Swarm users that from 21 to 28 January 2019, the ASM (Absolute Scalar Magnetometer) instrument on board Swarm Bravo was commanded in burst mode. Thus, the magnetic field intensity derived from the ASM and stored in MAGB_LR_1B and MAGB_CA_1B products is set to zero from 21 January 2019, at 07:36 UTC to 28 January 2019 at 06:54:23 UTC.

Swarm Bravo: STR instrument set at 2 Hz rate from 17 October 2018

18 January 2019

We would like to inform Swarm data users that from 17 October 2018, at 08:24:51 UTC, the attitude information of the Star Tracker instrument on board Swarm Bravo is provided at 2 Hz rate, instead of the previous 1 Hz.

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

With reference to the news published on 04 May 2017, we inform the Swarm users that the Swarm Alpha MAGx_LR_1B data from 29 April to 01 May 2017 have been regenerated and now can be found in the ESA FTP server.

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.
