    6363This 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.
    64 The period includes a season of ‘Short Eclipses’ in February - March 2020, when all instruments will be switched off. Preliminary dates for the eclipses are: on SC3 and SC4 24/02/2020 01:30 - 15/03/2020 12:30 and on SC1 and SC2 24/02/2020 01:30 -17/03/2020 19:20.
    65 
    66 There are also a moon eclipses:  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. The exact times of the no-data taking periods TBD.

     64The 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.

     66There 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.
     67
     68There is also 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.
     69 
    6870There are manoeuvres during this period, and a list is included here http://jsocwiki.rl.ac.uk/attachment/wiki/WikiStart/manoeuvres_dec2019-may2020.pdf.

    7880This 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.
    79 For the eclipse season the payload will be off, preliminary times are: on SC3 and SC4 24/02/2020 01:30 - 15/03/2020 12:30 and on SC1 and SC2 24/02/2020 01:30 -17/03/2020 19:20.

    81 This 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, and the science operations will cease for several hours around eclipse times, due to lack of power. Exact time of power off TBD.
