This segment covers the period from 11 September 2020 to 06 December 2020 (after the eclipse season) and has ~140% data volume as a baseline. 

The payload will be switched on after the eclipse on all spacecraft simultaneously on 13/09/2020 00:00. 

There are manoeuvres on 22/09/2020 on C3, C1 and C2; on 01/10/2020 on C3 and C2; on 02/11/2020 on C3; on 13/11/2020 on C3, C1 and C2; on 22/11/2020 on C3 and C2; and on 01/12/2020 on C2 and C3. For more information http://jsocwiki.rl.ac.uk/attachment/wiki/WikiStart/manoeuvres_may2020_dec2020.pdf. 

Cluster crosses the neutral sheet until early November and starts to cross magnetopause from 17/19 November 2020 (SC1/SC2) and from 26/11/2020 (SC3/SC4). 

Primary science targets are neutral sheet, the ECS GI programme on sub-ion magnetic holes in the plasma sheet, high-altitude cusp in the northern hemisphere, skimming magnetopause, and the ECS GI programme on the Cluster/MMS magnetopause conjunctions.
