Detlef Sieg, working on Cluster flight dynamics at ESA's ESOC operations centre in Darmstadt, Germany, said that they are optimising the Cluster formation so that the separation between Cluster 1 and the duo of Cluster 3 and 4 - which are on almost identical orbits - is kept below 100 km when the formation crosses Earth's magnetic equator.
