Scheduled time for Public Observing: 9pm – 11pm

Solar System Objects:

The Moon: will be 29° high in the SW at 10pm, and 72% illuminated (Waxing Gibbous phase, 9 days old).

Planets: Jupiter appears near the moon and will be available for viewing. Saturn will be 24° up in the South by 10pm, with Mars just rising in the SE. The positions of Jupiter’s major satellites at 10pm are shown below. The motion of it’s moons, especially if they appear close together, can be visible in only a few minutes.

Deep-Sky Objects:

Double Stars: One of the best double stars in the sky, Alberio, in the constellation Cygnus, will be visible all night. Easily seen as a single star to the naked eye, it resolves into a color-contrasting double in almost any telescope. The photo below was taken through an 8″ telescope (the author’s) using a smartphone.

The stars are different temperatures so therefore different colors, in this case yellow and blue. There still seems to be some debate as to whether the stars form a true binary system, or are a chance line-of-sight alignment. See the article here.

Nebula and Star Clusters: Despite moonlight, some deep-sky objects such as the globular cluster M13, and planetary nebulae NGC 6826 and M57 shown below may still be observable. Planetary nebulae (remnants of solar-type stars) tend to appear smaller than other types of deep-sky objects, but can have a higher surface brightness and shine through light-polluted skies.

Man-made Objects:

International Space Station (ISS): Any visible flyovers will be added closer to the observing date.

Iridium Satellites: These satellites can produce bright flares (brighter then Venus) from their antenna arrays. Any visible flares will be added closer to the observing date, as prediction accuracy improves.
