Neptune in Aquarius is rising in the east as public observing ends.

Uranus rises around midnight.

Venus and Mars are too close to the Sun to observe.

Constellations

The summer constellations are now visible rising in the August evening sky as twilight falls. Pegasus "The Winged Horse" is rising in the east along with Andromeda "The Princess of Ethiopia" and Aquarius "The Water Carrier". The Summer Triangle is rising in the southeastern evening sky. The triangle is formed by bright stars Vega in 'Lyra the Harp", Deneb in "Cygnus the Swan" and Altair in "Aquila the Eagle". The Summer Triangle is located rising in the eastern sky. Hercules the Son of Jupiter is overhead by 9:00 p.m. In the lower south is visible Scorpius "The Scorpion", Sagittarius "The Archer", and Capricornus "The Goat". The Big Dipper is low in the northwest sky as evening twilight ends. Using the Big Dipper to find north. See: Finding North Star. These are just a few of the many constellations visible this night.

Galaxies

There are many Galaxies and Globular clusters of star to be viewed this night and one of the best is Messier 13 The Great Globular Cluster in Hercules which is high in the sky this night. Another treat is Messier 92 only 9 degrees away from M-13 which is another Globular cluster. Swinging the telescope from the constellation Hercules is Messier 57 about 21 degrees above Messier 92. This is a Planetary nebulae, it looks like a small smoke ring in space which was caused by the central star exploding and the star is still visible through a large telescope if seeing is very good. The sky this night is full of many many more wonderful objects than listed above to see and we hope to see you at the observatory.

WHAT IS PUBLIC OBSERVING?

The York County Astronomical Society holds a public observing session every month, check this website for times. 

The club's telescopes will be used to show the public many of the fascinating objects that are up in the nighttime sky. We will also be showing people how to use Star charts to identify the stars and constellations that are up in the nighttime sky. The public is encouraged to bring their own telescopes, if they have one, to learn how to use them more effectively. If you are interested in buying a telescope, this is a great place to ask questions.
