 The two figures below show the relative timings of the Cluster spacecraft as they cross the magnetopause during the 2019 dayside constellation (November 2018 to July 2019) - the first figure shows inbound crossings whilst the second shows outbound crossings. The solid lines indicate the crossing times of the four spacecraft using the standard colour scheme: black for C1, red for C2, green for C3 and magenta for C4. All times are relative to the C1 crossing time, with positive times indicating a cross occurring before the C1 crossing time.
 
-The grey dotted line indicates the crossing time for the centroid of all four Cluster spacecraft, which has traditionally been used by JSOC for targeting burst mode data-taking around magnetopause crossings. This targeting is probably not appropriate for the 2019 constellation.

+During this constellation it may be better target burst mode data-taking on boundary crossings by the centroid of a subset of the four Cluster spacecraft. Some of those centroid crossing are shown in the figures below. Lists of some of these crossing are also available for download as Excel files - see the attachments to this page or the links below:

 These figures are based on the long-term orbit data delivered by ESOC on 30 July 2018.
