WHPI spans the entire solar minimum period (approximately end of 2018 to beginning of 2020). For the purpose of coordinating targeted observations, we have identified a few focus “campaign” time periods that take advantage of solar-heliosphere-planetary synergies including, for example, PSP perihelia. To help stimulate collaborative activities, we also note other time intervals with interesting synergies. However, we emphasize that WHPI science is not limited to these time periods.
