Adding Solar Orbiter's senses to the heliosphere: how we work with the community to get the best out of the combined viewpoints of an interplanetary explorer and assets elsewhere.

The nominal mission phase of Solar Orbiter began at the end of last year, and at the time of this meeting, the spacecraft will have made two perihelion encounters with the Sun, first at 0.32 AU, and most recently at 0.29 AU.

The first windows of concentrated intense cross-payload coordination, around perihelion passage, gave us the first in-flight experience of two major aspects of this intense period of coordination of the science operations: the late updates to pointing for those observation programmes (SOOPs) requiring a specific target on an ever-changing body (active regions, coronal hole boundaries); and working with the wider Heliophysics community to both determine the exact pointing for these targets and communicating this in more familiar coordinate systems once decided.

We present the problems of inter-mission coordination, and the solutions encountered, during the first two close perihelia of Solar Orbiter. We also discuss the timelines for the most effective cooperation with external observatories, given the deadlines of the various planning cycles of Solar Orbiter.
