 This period covers 8 Dec 2019 - 06 June 2020 (orbits 3067 – 3146). The Bryant plot for this period is on JSOCweb http://www.jsoc.rl.ac.uk/msp/bryant_msp4200_Dayside_2020.pdf.
-The period includes a season of ‘Short Eclipses’ in February - March 2020, when all instruments will be switched off. The dates for the eclipse period when the payload will be switched off: on SC3 and SC4 24/02/2020 12:00 - 15/03/2020 00:00 and on SC1 and SC2 are 24/02/2020 12:00 - 17/03/2020 00:00. During this eclipse season in order to accommodate BM1 requests for the Cluster /MMS conjunctions, payload will be switched on for the two periods  which will be managed by ESOC: (i) 20/03/03 09:30 – 12:00, BM1 mode; (ii) 20/03/10 05:40 - 10:20  1h NM1 + 2.5h BM1+1h NM1.

 There is a moon eclipse on three spacecraft:  on C4 on 24 January 2020, 14:23 - 15:00; on C1 on 24 January 2020, 15:05 - 15:16; on C3 on 24 January 2020, 15:28-16:00, on C2 on 22 April 2020, 09:44-10:28; and on C1 on 22/04/2020, 10:06 - 10:49. Due to the different power profiles, the moon eclipse impact for each spacecraft varies. On C1, which is not affected much, there is no constraints on the payload and TDA6 periods, payload will stay on. On C1 the WBD operations are not allowed during the period 24/01/2020 12:00-18:00. On C3, there will be 'Power Limited' platform configuration: with the CIS, PEACE, WEC and FGM instruments being off during the period 24/01/2020 15:00 - 16:30. In addition, there will be no BM1 and BM2 modes allocated during the same interval, and no WBD operations during the interval 24/01/2020 12:00 - 18:00. On C4, all payload will be switched off for the period 24/01/2020 06:00 - 25/01/2020 00:00, there will not be any BM1 and BM2 modes allocated during the period 24/01/2020 00:00 - 25/01/2020 and no WBD operations during the period 24/01/2020 00:00 - 25/01/2020 00:00.

 This segment covers the period from 8 December 2019 to 14 March 2020 (before the eclipse season as well as majority of time during eclipse season) and has 130% data volume as a baseline, however in some orbits the data rate was increased above the baseline value. 
-For the eclipse season the payload will be off, the eclipse times are: on SC3 and SC4 24/02/2020 12:00 - 15/03/2020 00:00 and on SC1 and SC2 are 24/02/2020 12:00 - 17/03/2020 00:00.
