While smaller spots with the correct polarity alignment of cycle 25 regions have been observed at high latitude locations, this overview will only include spots large enough to have been visible at a 1K resolution. In the case of reversed polarity cycle 24 regions, those that are not at a sufficiently high latitude (ie. 30 degrees or more), are considered to most likely to belong to cycle 24 and will not be included in this list until closer to the actual solar cycle minimum (likely to be sometime between July 2018 and January 2020).
