Get yourself and your boat(s) ready. Bring the kids. Bring the lights!
Meet out in the center of the lake starting between 7:00-7:30pm. Sunset on 9/10 is 7:13pm and “nautical twilight” ends 8:13pm (stars start to appear). Astronomical twilight ends at 8:47pm (darkness). The moon is full on this day, so it will rise in the east at 7:45pm and it will start to be visible above the treeline about 30 minutes later.
See you out there!
