The Fuertes Observatory is open for public viewing every Friday evening when school is in session and occasionally at other times. During the academic year, meetings of the Cornell Astronomical Society also take place before the open house nights.

The Sky Tonight (June 2015)

The Moon is full on the 2nd and interferes with observation of fainter objects in the early days of the month.

The summer constellations rise into view over the month and become well placed for open house viewing. Messier 13, the great globular cluster in Hercules, is well placed at Sunset. Somewhat later, the constellation Lyra with its bright star Vega and the nearby Ring Nebula become visible. Other summer targets along the Milky Way are the Dumbbell nebula? and the double star Albireo?.

Jupiter and Venus? approach one another ever closer in the western sky at sunset, moving towards a spectacular conjunction on June 30. They are joined by the crescent moon on June 19th. Saturn is well placed throughout the evening for observing in the southern sky. The other planets are not well placed for evening viewing during June.

High overhead in the North, the twin galaxies M81 and M82? can be found near the bowl of the Big Dipper.

The Milky Way lies near the horizon, where it is invisible, at sunset. As the summer constellations rise with it it begins to come into view in the later hours of open house nights if sky conditions are excellent.

The planets, Moon, and a number of brighter "deep sky" objects are popular targets with the Irving Porter Church telescope and smaller instruments.

Visiting Fuertes Observatory

When you attend an open house, please respect other observers and your hosts by refraining from the use of flash photography, white flashlights, open cellphone displays, and other sources of bright light in the telescope dome and on the observing deck when observing is in progress. It is necessary to spend several minutes in a darkened environment before the eyes adapt to seeing faint celestial objects, and bright displays interfere with that adjustment.

Please dress warmly appropriate to the season: the telescope dome and deck are unheated. Even in the spring and fall months, temperatures may cool rapidly after dark.

Children are welcome, but must be accompanied by an adult at all times.

Common Telescope Targets

Most objects that can be seen with the Fuertes telescope are related to active research by Cornell's Department of Astronomy and Center for Radiophysics and Space Research. A selection follows.
