I was about to set out on one of my regular walks at Upolu, when I looked up and saw this halo around the sun. It’s the first I’ve seen here (which doesn’t mean there haven’t been others).
In days of yore, halos were considered a sign of impending bad weather. In this case, there’s some evidence to back that up. The ice crystals that cause halos are found in clouds, high in the troposphere, and these clouds are often a sign of an approaching weather front. Sure enough, the next day was fairly wet though, ironically, not in the area where I saw the halo.
