See the CNYO Brochure Archive Page for background more information.
Because these are still asked for/about – and because the cnyo.org website continues to suffer from WordPress-related aging that may make it less-and-less accessible as time progresses, the original brochures put together as hand-outs at hosted events and star parties have been embedded into the page below for your reading and downloading pleasure.
These two-page brochures were printed out double-sided, tri-folded into pamphlets, and handed out at lectures and observing sessions. The PDFs should print just fine with no cut-offs in any modern printer.
These include the following:
- A Guide For New Observers (original post, local PDF, local page)
- A Guide For Solar Observing (original post, local PDF, local page)
- A Guide For Lunar Observing (original post, local PDF, local page)
- How The Night Sky Moves (original post, local PDF, local page)
- A Guide To Meteor Showers (original post, local PDF, local page)
A Guide For Lunar Observing
Some Interesting Facts About The Moon
620 millions years ago, the day was 21.9 hours long and one year was 400 days!
Phases Of The Moon
With respect to a fixed spot over the Earth’s surface, the Moon completes one orbit in a
sidereal month – 27 days, 7 hours, and 43 minutes.
The Blue Moon (Not Really Blue)
Since the synodic cycle of the Moon (FM to FM) is 29.5 days, a FM at the very beginning of a month will result in a FM at the end of same month.
The Man In The Moon & Other Features
The surface of the Moon shows evidence of the violent nature of the early Solar System.
The Moon – Not Just A Pretty Face!
On the side of Earth nearest the Moon, lunar gravity is strongest, pulling the water up slightly (“sublunar” high tide).
Can I See The American Flag?
There is lots of equipment left on the Moon from manned and unmanned missions, but Earth-based and many space-based telescopes do not have the resolving power to see any of it.
The Dark Side Of The Moon
The Moon’s orbital period and rotation period are the same – as it makes one trip around the Earth, it completes one spin on its axis – this is called “Tidal Lock,” and is why we only ever see one side from Earth.
