8th Swarm Data Quality Workshop report published in EOS

27 May 2019

The eighth Swarm Data Quality Workshop was held at ESRIN (Frascati, Italy) from 8 to 12 October 2018. This workshop was instrumental in addressing the processing and use of Swarm data and defining a road map for the future.

Swarm Alpha: L1B ASM data gap from 13 to 20 May 2019

21 May 2019

We inform the Swarm users that from 13 to 20 May 2019, the ASM (Absolute Scalar Magnetometer) instrument on board Swarm Alpha was commanded in burst mode.

Swarm Alpha: EFI data gap on 12 May 2019

17 May 2019

We would like to inform Swarm users that an EFI/TII gain calibration map has been executed on 12 May 2019 onboard Swarm Alpha.

Tug-of-war drives magnetic north sprint

15 May 2019

As far as we know, Earth's magnetic north has always wandered, but it has recently gained new momentum and is making a dash towards Siberia at a pace not seen before. While this has some practical implications, scientists believe that this sprint is being caused by tussling magnetic blobs deep below our feet.

Significant improvements on Swarm Thermal Ion Imagers data

07 May 2019

The constant improvement in the strategies to operate the two Thermal Ion Imagers (TII) sensors on-board each Swarm spacecraft, defined by scientists and engineers in dedicated monthly TII anomaly review board meetings, allow a significant increase in TII data coverage, and a substantial improvement in TII data quality.

Swarm Charlie: data gaps from 28 Apr 2019

06 May 2019

We would like to inform Swarm users that an on-board anomaly occurring on Swarm Charlie caused data gaps on all L0, L1A and L1B data products from 28 April 2019 onwards.

Swarm helps explain Earth’s magnetic jerks

01 May 2019

Our protective magnetic field is always restless, but every now and then something weird happens – it jerks. Although scientists have known about these rapid shifts for some 40 years, the reason why they occur has remained a frustrating mystery, until now.

Swarm Bravo collision avoidance manoeuvre on 2 April 2019

03 April 2019

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.

Swarm Alpha and Charlie: STR instruments set at 2 Hz rate from December 2018

15 March 2019

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.

CASSIOPE/e-POP full data mirror on the ESA Swarm Dissemination Server

06 March 2019

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.
