Do you live in the Washington, DC area? Are you going to be around DC in two weeks? Then come enjoy close-up views of the crescent Moon, Venus, Mars, Saturn, star clusters, and nebulae. You can even gaze at our own Sun early in the evening with the help of specially filtered telescopes. OSTP, in conjunction with Hofstra University, will co-sponsor a free, open to the public star party July 15 on the National Mall in Washington, DC.
