Swarm Operational News
18 September 2018
On 17 September 2018 an improved version for both L1B and L2 Cat-2 Operational Processors was transferred into operations. We are in the process of publishing the entire datasets generated with the latest processor versions (L1B and L2 Cat-2 outputs with the following Product Baseline and File Counter: ORBATT 0401; MAGNET 0505; PLASMA 0501; ACCELE 0501; IBI 0301 ; FAC 0301; TEC 0301)

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.
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.
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.
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.
Modelling of non-gravitational forces such as drag or solar radiation pressure requires knowledge of the thermo-optical properties and geometry of the outer surfaces of the spacecraft. These are now provided in a memorandum and can be accessed here.

All validated Swarm Level 1b and Level 2 products are now freely accessible to all users via anonymous FTP or any HTTP browser.
ESA has started a process to improve the Earth Observation data distribution services, aiming at facilitating access to data and information for the end users, initially by shortening the access path and reviewing authentication and authorisation processes.
05 June 2018
Due to an anomaly that occurred on the VFM (Vector Field Magnetometer) on board Swarm Alpha, the VFM science data (at 50 Hz rate) was not received from 02 June 2018 at 09:52 UTC to 03 June 2018 at 09:14:34 UTC.
01 June 2018
On 30 May 2018 a technical issue caused a telemetry data gap in S/C C from 21:14:47 to 23:12:23 UTC.
25 May 2018
An anomalous variation in the Inter Boresight Angle (IBA) for Camera Head Unit (CHU) pairs A-C and B-C has been observed for Swarm Charlie from 07 May 2018 at 09:34 UTC.
16 May 2018
An EFI TII gain map calibration was performed on the Swarm Charlie satellite on 28 February 2018. The instrument was in calibration mode for two orbits.
An orbit collision avoidance manoeuvre was performed on Swarm Bravo on 16 April 2018 at 16:10 UTC for a duration of 96 secomds equivalent to a Delta V = 2 cm/s.
18 April 2018
Due to an anomaly that occurred on the VFM (Vector Field Magnetometer) on board Swarm Charlie, the VFM science data (at 50 Hz rate) was not received from 13/04/2018 19:18 UTC to 16/04/2018 09:21 UTC.
09 April 2018
The first models of the fourth release of Swarm magnetic field models are now available to users. The new models are based on improved Swarm magnetometer data (MAGx_LR_1B data products, baseline 05, version 03), covering the period from launch to the end of 2017, i.e. one additional year in comparison to the previous release.
We would like to inform the Swarm users that the 2 Hz Langmuir Probes extended dataset coverage has been increased in the ESA FTP server. The time coverage will be updated on a daily basis. Data now cover the time interval from 02 December 2013 to the current date - 14 days for all Swarm spacecraft.
We are pleased to inform the Swarm users that an improved version of the Swarm 16 Hz faceplate density dataset (Product Baseline and File Counter 0201) is now available in the /Advanced/Plasma_Data/16_Hz_Faceplate_plasma_density folder on the Swarm FTP server.
We would like to inform the Swarm users that the 2 Hz Langmuir Probes extended dataset coverage has been increased in the ESA FTP server. The data now cover the time interval from 02 December 2013 to 11 December 2017 for all Swarm spacecraft.
15 February 2018
We would like to inform the Swarm users that the 2 Hz TII Cross-Track data flow dataset has been extended in the ESA FTP server.
