For a mere minute an elusive fogbow appears, as the sunrise falls into the fog drifting above the marsh.
Its somewhat uneven brightness stems from fog density variation, both in front and behind me, causing the sunlight and its reflection to shift with the hovering fog.
Normally the lower ends of the arch would stand out stronger than the rest, but here floating low fog on a lake behind me subdues the sunshine
closer to the ground, mostly canceling out that effect.
