Katahdin Viewpoint
Katahdin Woods and Waters NM
"Setup on the road in the clearing at the "Katahdin Viewpoint" site on the loop off of American Thread Road. This site does not quite have the big open views found at the Overlook in the SW section of the park, but does provide an easier access site for public viewing events. A fair amount of cirrus clouds along the horizon to the north and west before sunset that slowly dissappeared by the end of astronomical twilight. A few persistent clouds remained during data collection, including some distant clouds over Quebec City (130 miles to the west) that enhanced the sky glow from the city. Aside from that location, there were no light domes or single sources visible from this site. Humidity was again very high this night and created higher extinction values towards the horizon. Still very good night sky observing possible from this site and good detail visible in the Milky Way and other features in the sky."
The Overlook
Katahdin Woods and Waters NM
"A very good site for night sky observing, with clear views down to the horizon from the south almost to the north. Slight blockage from trees to the east, but no more than 10°-15° above the horizon. Almost no perceptable light domes or sky glow anywhere, and just a few single source unshielded lights on the south shore of Millinocket Lake (almost 10 miles distant). Lots of clouds throughout the day from a passing cloud front, but skies cleared completely by 7:00pm and lack of wind made for good seeing. Very high relative humidity contributing to slightly higher extinction along the horizon. The Milky Way is very bright from south to north and good detail visible in the Sagittarius and Cygnus star clouds and M31 easily visible to the naked eye. Lots of meteors throughout the evening, but not many overflights. Vehicle headlights brightened images 44 & 45 (at the zenith) in set #1. Banded airlgow fairly prominent in sets 2 & 3. The best night sky this observer has seen anywhere east of the Mississippi River outside of the Northern Great Lakes. SQM reading of 21.52."
