The sunrise has been getting earlier with each passing day, and the time gained has been accelerating. We have already gained over 15 minutes since the beginning of the month which saw the latest sunrise of the year. I notice the first signs of twilight along the University trail as I near Highland Avenue. As I approach Lake Wingra still in nautical twilight but there is typically a well defined light on the horizon. Civil twilight begins around 6:45 am where I likely along Waunona Way. At this point there is enough light I start using my strobing headlight. I switch to this light when the ambient light is high enough I don’t notice the strobe flashes in reflections. Next month the sunrise will move forward by over 30 minutes and I should likely be seeing twilight while starting my ride.
