Equatorial Flux Cancellation Imprinted in Solar Wind Helium: A Reliable Herald of the Solar Cycle Transition

Background: Predicting the onset of a new solar cycle is challenging because the sunspot minimum can only be identified retrospectively. A real time, in situ proxy is needed. Purpose: We investigate whether the solar wind helium abundance ( A He ) provides a reliable herald of cy...
