  We investigate the occurrence of the "extended solar cycle" (ESC) as it
occurs in a host observational data spanning 140 years. Investigating coronal,
chromospheric, photospheric and interior diagnostics we develop a consistent
picture of solar activity migration linked to the 22-year Hale (magnetic) cycle
using superposed epoch analysis (SEA) using previously identified Hale cycle
termination events as the key time for the SEA. Our analysis shows that the ESC
and Hale cycle, as highlighted by the terminator-keyed SEA, is strongly
recurrent throughout the entire observational record studied, some 140 years.
Applying the same SEA method to the sunspot record confirms that Maunder's
butterfly pattern is a subset of the underlying Hale cycle, strongly suggesting
that the production of sunspots is not the fundamental feature of the Hale
cycle, but the ESC is. The ESC (and Hale cycle) pattern highlights the
importance of 55\degree\ latitude in the evolution, and possible production, of
solar magnetism.
