GENERAL INFORMATION about the planetarium and observatory:
       # Public Nights are free, but we do accept donations in the planetarium and in the hyperbolic funnel ("black hole") in the lobby.
       # Planetarium shows will be held as scheduled, rain or shine, unless severe storms or hazardous driving conditions are predicted. The telescope cannot be used if skies are cloudy or precipitating. (Use the National Weather Service link, below, to see the forecast for any scheduled Public Night date.)

       # Parking is very limited (4 to 6 vehicles) atop the hill where the facility stands, but more is available on University Boulevard (the main Westside Campus road).
       # The planetarium has a seating capacity of 40. The telescope chamber can accommodate 6 to 8 at one time, with additional standing space on the stairs.
       # Planetarium shows usually last about one hour and are geared to adults and families with preadolescent and older children; i.e., older than baby or toddler. Younger children may be disturbed by the dimming of lights in the planetarium and other special effects.
       # It is requested that people attending planetarium shows turn off mobile phones, digital cameras and other electronic devices, as their use during the show is disturbing to others. The same request holds for flashlights, lighted sport shoes and other sources of illumination.
       # The observatory houses a 20-inch f/8.1 Ritchey-Chretien reflecting telescope that is used for public observing and astronomy research by WCSU students and faculty. It has a German-type equatorial mounting (the telescope has counterweights) and a computer controlled pointing and tracking system.
DRIVING DIRECTIONS to the WCSU Observatory and Planetarium:
        The facility is located on the WCSU Westside Campus, which is off Exit 4 (Lake Avenue) of Interstate 84. After exiting the Interstate, travel about 0.7 mile west on Route 6 to the main campus entrance, then another 0.7 mile up the main campus road, University Boulevard. You will pass Centennial Hall (new dormitory) on your left; continue straight. At the new Campus Center (on the right), turn left and proceed a short distance to the observatory road, which will be on your left and facing the Pinney Hall dormitory.

PLANETARY INFORMATION

MERCURY

reappears in the evening sky during the last week of January, with its best after-sunset appearance of 2013 during February (greatest eastern elongation on Feb. 16). It then passes back into the Sun's glare and reappears before sunrise around mid-March, reaching greatest western elongation on Mar. 31. It is still visible before sunrise during April, then again vanishes into the Sun's glare and reappears after sunset in late May. It's a speedy little planet!

VENUS

is visible low in the ESE pre-dawn sky during January and February, thereafter lost in the Sun's glare until May, when it can be glimpsed low in the west after sunset.

MARS

is low in the WSW twilight sky during January and most of February. Thereafter, it vanishes into the Sun's glare and is not visible again (low in the ENE pre-dawn sky) until June.

JUPITER

in Taurus, is well placed for viewing all spring. It gradually moves from the eastern evening sky into the western evening sky. By May, it is low in the WNW twilight sky, gradually vanishing into the Sun's glare.

SATURN

in Libra, rises in the SE around midnight during February, but ever earlier as spring progresses. The planet reaches opposition on April 27, rising around sunset and visible most of the night.
