 * Additional segments will be defined in due course for the period after the long eclipses
 
-There will also be "moon eclipses" on 8 November 2018. On that day each spacecraft will spend about one hour passing through the Moon's shadow. Thus we expect that science operations will cease for several hours around these eclipses, due to lack of power. These eclipses will take place when the Cluster spacecraft are around 100000 km from Earth (mainly in the GSE +Y direction), so are not associated with eclipses seen from Earth.

These eclipses will take place when the Cluster spacecraft are around 100000 km from Earth (mainly in the GSE +Y direction), so are not associated with eclipses seen from Earth. Science operations will be limited around these eclipses, due to lack of power. The instruments on C1, C3 and C4 will be switched off for two days, from 03:00 on 7 November until 03:00 on 9 November. In addition, there will be no BM1, BM2 or WBD operations on these three spacecraft in the 15 hours prior to instrument switch off, i.e. after 12:00 on 6 November. C2 operations are less restricted: the instruments on this spacecraft will remain on during the eclipse period, except PEACE and WEC will be switched off for 3.5 hours, from 18:30 to 22:00 on 8 November. In addition, there will be no BM1, BM2 or WBD operations on C2 between 12:00 on 6 November and 22:00 on 8 November.

 There are manoeuvres during this period, and a list is included here http://jsocwiki.rl.ac.uk/attachment/wiki/WikiStart/manoeuvres_may-oct2018-v1.pdf. The  magnetopause is accessible at the start of MSP39 and at the very end, and the neutral sheet will be accessible for most of the MSP.
