This segment covers the period from 30 June 2023 to 22 September 2023 (ending during the Autumn 2023 eclipse season).

The preliminary dates for the payload to be off during the long eclipses season are (the exact dates are TBC by ESOC):

• C34 13/09/2023 10:00 - 23/09/2023 18:00
• C1 19/09/2023 05:00 - 02/10/2023 13:00
• C2 19/09/2023 21:00 - 04/10/2023 17:00

Baseline telemetry is 140% overall, although a telemetry volume is variable to accommodate the science targets.

There will be no moon eclipses in this segment.

There will be a manoeuvre on SC2 on 17/09/2023, for more information please see ​​http://jsocwiki.rl.ac.uk/attachment/wiki/WikiStart/manoeuvres_nov2022_nov2023_v2.pdf.

Cluster crosses the predicted magnetopause until: C34 - 24/06/2023, C1 - 29/06/2023, C2 - 03/07/2023.

Cluster crosses the predicted neutral sheet in the tail from: C34 - 16/07/2023, C12 - 12/08/2023.

The main science targets are conjunctions between Cluster and MMS and/or THEMIS in the plasma sheet, and auroral acceleration region in the northern hemisphere.
