Correlated Studies at Activity Maximum: the Sun and the Solar Wind

The breadth and power of the set of solar and helio-spheric observatories presently in space is unprecedented. Their observations generally began at solar minimum or in the declining phase of the past maximum , but we anticipate that most of the instruments will be able to observe the rise to the next maximum and the events that happen then. The second orbit of Ulysses will be especially interesting and the Yohkoh orbital decay is not projected until 2002. New spacecraft, including TRACE, HESSI, and SOLAR-B, may also become available. The current remote-sensing and in-situ measurements are characterized by a much stronger understanding of how the solar and interplanetary phenomena match. In this paper we review novel discoveries from the current data and speculate about how to take advantage of the future data, emphasizing the use of heliospheric observations to help probe the connectivity of the corona/solar wind interface region.
