I watched the object for more than an hour through my scope and took photos. It was drifting but very slowly. Based on my research it matched perfectly a super pressure balloon used by NASA for various research projects. Balloons like these are the size of football stadium and cruise above 100,000 feet. Based on the sightings, it was visible from anywhere in NH. Pretty cool!
