The New Hampshire Astronomical Society will present a skywatch program at the James A. Tuttle Library in Antrim on Tuesday, Sept. 10, from 8 to 10 p.m.

Members of the Astronomical Society will arrive before sunset, set up their equipment and choose their celestial targets with public education and outreach in mind. An educational slide presentation may also precede the skywatch if a suitable venue is available.

The event is free and open to the public.
