英文摘要	In the outer heliosphere, higher upstream Alfvénic Mach number (MA) values have been theorized to limit the solar wind forcing at all giant planet magnetospheres. To determine the true impact of MA on the ability for magnetopause reconnection to occur, we perform a comprehensive analysis using data collected throughout the heliosphere. We find that solar cycle variations in solar wind magnetic pressure lead to wide ranges of upstream MA in the outer heliosphere, where MA at solar maximum appears Earth-like. These considerable MA variations combined with the significant magnetic dipole tilts at Uranus and Neptune suggest that magnetopause reconnection may yet play an important role at the ice giants, in particular at solar maximum. Published 2020. This article is a U.S. Government work and is in the public domain in the USA.
