An orbit collision avoidance manoeuvre was performed on Swarm Bravo on 2 April 2019 at 00:23 UTC for a duration of 64 seconds, equivalent to a Delta V of 0.015 m/s.
We would like to inform Swarm users that from 12 December 2018, at 13:34:56 UTC and 18 December 2018, at 12:43:30 UTC, the attitude information of the Star Tracker instruments on board the Swarm Alpha and Charlie satellites, respectively, are provided at 2 Hz rate, instead of the previous 1 Hz.
The ESA Swarm Dissemination Server is now also hosting a mirror of the CASSIOPE/e-POP full data archive (past and current observations) in native format. These products are freely available under the /#CASSIOPE_e-POP directory by FTP/HTTPS anonymous browsing. Read a full description of the e-POP data set.

A new Swarm Level 2 data product was released on 20 February 2019. It contains several time series that characterize the plasma density and plasma irregularity along the Swarm orbits, separately calculated for each of the three satellites.

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.

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.
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.

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.
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.

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.
