This star party offers another opportunity each month to observe under a dark sky. It's open to all SAS members but is specifically designed to orient new members to dark-sky protocol. Although dark-sky etiquette is expected (see below), experienced members will be on hand to help newcomers learn the ropes.

The Third Quarter Star Party is for SAS members only and will be on Saturday, September 29, 2018, at 9:00 p.m. if weather permits.
