Average PMC intensity 23 days after solstice for the north pole (top) and south pole (bottom) as measured by the CIPS instrument. The PMC occurrence frequency began slowly in the south compared to the north. However the number of clouds in these equivalent-day images appear similar. Is the south catching up? Stay tuned!
