MSP 41.1

This segment covers the period from 25 May to 06 September 2019 (before the eclipse season). The magnetopause is accessible until late June, and the tail neutral sheet from early July. The primary BM1 science target is the Cluster/MMS conjunctions in the magnetosheath and at the magnetopause and Cluster skimming magnetopause, followed by the neutral sheet crossings centred on C3/C4 with C1 and C2 being in the opposite lobes.

There are manoeuvres on 16 July (C3), 5 August (C1, C2, C3) and 14 August (C1, C2, C3). This segment includes a moon eclipse on C1 on 1st July 2019, and the science operations will cease for several hours around this eclipse, due to lack of power. The instruments on C1 will be switched off for the period 01/07/2019 06:00 - 02/07/2019 06:00. In addition, there will be no BM1, BM2 or WBD operations on C1 between 30/06/2019 00:00 and 02/07/2019 06:00.

The MSP41.1 was updated on 30/04/2019 in order to accomodate moon eclipse margins, with some science operations changes.
