I arrive at dawn to catch the sunrise, dressing snugly in my hooded jacket, long pants, long socks and gloves. Today’s icy wind is just enough to keep frost off car windows and grass. Frost coats the bridge deck and I feel its slippery surface beneath my feet. One duck braves the cold for an early swim back and forth across the river.
Why is the sun bright yellow when looking at it in daylight; yet at sunrise and sunset, we see shades of orange from pale pastel to dark and fiery?
Every morning brings a new set of cloud formations and different ways to diffuse and reflect the sun’s brilliance. Today clouds are woven as if they were a heavy gray blanket hanging over the river. Patterns of light change and spread as the sun edges closer to the horizon, painting the sky at dawn with brilliant colored light a full 30-40 minutes before the sun shows itself.
