Marconi Overlook
Cape Cod NS
Local Relevance
Yarmouth Port enthusiasts typically use the instrumented readings from Marconi Overlook to calibrate their deep-sky expectations for the area.
"Transparency good, daytime visibility 20 miles, seeing very good. Due north are some lights as bright as Jupiter, but all in all dark adaptation possible. Darkest part of the sky zenith and east of zenith, a circle of uniform darkness 15-20 degrees diameter. All around the sky is a glow, however, artificial, even with the ocean to the east. Brightest light dome Provincetown west, mingled with other towns to the south. About 200 degrees of the horizon is polluted from north to south. Light dome NW peach color, 60 degrees tall, 70 degrees wide, north 30 degrees tall, much dimmer. The combined light of these light domes definitely casts a shadow, but is soft, navigation is possible but not easy by this light. Ocean reflects light from the sky, but with dunes blocking light domes a good idea of night is achieved. Later as the Milky way rises, an idea of the natural night sky is definitely available, gegenschein is barely visible."
