Fall 2025 Schedule -- ONU Observatory
Maps to the ONU Observatory can be found
here.
Sunday, Aug 24, 8:30-9:30 pm. -- ONU Event. "Welcomefest
Meet-n-Greet" Descriptions of each event will appear in the week leading up to the event. Friday, Sept 19, 8:30-10:30 pm. -- Public Event. "Autumnal Equinox Star Party"
ONU and surrounding communities are invited to drop by the ONU Observatory
between 8:30 and 10:30 pm this Friday, September 19 for an autumnal equinox
star party! The autumnal equinox is the start of fall and it officially
happens on September 22 at 2:19 pm Eastern this year. It is called an
"equinox" because the length of the daytime hours are about equal to the
length of the nighttime hours. Equinoxes are special in that the Sun
will rise due East and set due West around those dates. This date also
happens to be just before the opposition of
Saturn (9/20) and Neptune (9/23). This means that those 2 planets will
be about as close to the Earth as they get, making them look bigger
than average in the eyepiece. It will be a moonless night so we can
look at fainter clusters, nebulae, and galaxies.
Also, the observatory has a new refractor telescope!
This event was a success!
Friday, Sept 26, 8:30-10:30 pm. -- Public Event. "Saturn and Neptune at their closest"
The ONU and Ada communities are invited to drop by the ONU Observatory
between 8:30 and 10:30 pm this Friday, Sept 26 for "Saturn and Neptune
at their closest". The actual days of opposition for Saturn and
Neptune are September 20 and September 23, respectively. These are
approximately the dates of closest approach to the Earth and so these
planets will look relatively big and bright through our telescopes and
remain so for the next several months.
Ringed Saturn and blue Neptune will be only about 3 degrees apart and
situated in the East. Meanwhile the crescent Moon will set in
the West by 9:30 pm, allowing us to observe fainter objects.
The forecast (as of 9/23) is for only 15% cloudcover, so conditions should be good for observing. Check this sight on Friday in case conditions change.
This event was a success!

Arrange a tour or visit?We encourage your K-12 students and other organizations to visit during the Public Events listed above. However, you may be able to schedule a special visit. We can comfortably fit about 60 people in the observing room. Bigger groups can still attend. During the daytime, we will show you the building and telescopes and, if clear, can view the Sun! We don't roll back the roof if there is precipitation. If interested, contact the Observatory Manager:Dr. Jason Pinkney ONU Dept of Physics and Astronomy 525 S.
