a vee of wild geese
cross a pink pillar of light
above the vanished sun
Scientists say that the solar pillar is not actually a vertical ray from the sun but rather the collective glints from millions of ice crystals high in the atmosphere. The small clumpy clouds that look like fish scales or a school of fish hovering above the pillar are altocumulus. These high, heaped clouds are formed by the lifting of air in advance of a cold front. The old proverb, "Mackerel scales and mare's tails make lofty ships carry low sails," refers to the common experience of clumpy or wispy clouds on a warm, humid summer morning followed by a thunderstorm later in the day, a warning that the ship should lower its sails to protect them from high winds. But this is winter, not summer, and the buttermilk clouds appear at sunset, followed by a tumult of stars.
