    8282This 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.

    8384For 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.
    8485
    85 During this eclipse season in order to accommodate BM1 requests for the Cluster /MMS conjunctions, payload will be switched on for the two periods: (i) 20/03/03 09:30 – 12:00, for 1.5h of the BM1 mode; (ii) 20/03/10 05:40 - 10:20 for 1h NM1 + 2.5h BM1+1h NM1

    8786This segment includes a moon eclipse on C1, C3 and C4 on 24 January 2020, on C4 during the period 14:23 - 15:00; on C1 during the period 15:05 - 15:16; on C3 during the period 15:28-16:00. 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.

    102 This segment covers the period from 14 March 2020 to 06 June 2020, after the short eclipse season. 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. 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.

    104100This segment has 135% data volume as a baseline, however in some PPs the data rate can be increased up to 140% if required due to science targets allocation.
    105101
    106 This segment includes a moon eclipse on 22/04/2020 on C2 during the period 09:44-10:28, and on C1 during the period 10:06 - 10:49. The science operations will cease for several hours around eclipse times, due to lack of power. Exact time of power off TBD.
     102This segment includes a moon eclipse on 22/04/2020 on C2 during the period 09:44-10:28, and on C1 during the period 10:06 - 10:49. The science operations will cease for several hours around eclipse times, due to lack of power. Exact timing for the moon eclipse is: payload is off for the period 22/04/2020 00:00 - 22/04/2020 18:00 on both C1&C2; no WBD operations during the period 21/04/2020 06:00 - 22/04/2020 18:00 on both C1&C2; no BM1&BM2 intervals during the period 21/04/2020 12:00 - 22/04/2020 18:00 on both C1&C2.
