October is eclipse month!

To Ambassadors of Astronomy, Please inform your friends and co-workers,
A total lunar eclipse will take place on 8 October 2014. It is the second of two total lunar eclipses in 2014, and the second in a tetrad (four total lunar eclipses in series). Other eclipses in the tetrad are those of April 15, 2014, April 4, 2015, and September 28, 2015.
The planet Uranus will be near opposition (opposition on October 7th) during the eclipse, just over 1° from the eclipsed Moon. Shining at magnitude 5.7, Uranus should be bright enough to identify in binoculars. Due to parallax, the position of Uranus relative to the Moon will vary significantly depending on the viewing position on the surface of Earth.
The Moon does not completely disappear as it passes through the umbra because of the refraction of sunlight by the Earth’s atmosphere into the shadow cone; if the Earth had no atmosphere, the Moon would be completely dark during an eclipse. The red coloring arises because sunlight reaching the Moon must pass through a long and dense layer of the Earth’s atmosphere, where it is scattered. Shorter wavelengths are more likely to be scattered by the air molecules and the small particles, and so by the time the light has passed through the atmosphere, the longer wavelengths dominate. This resulting light we perceive as red. This is the same effect that causes sunsets and sunrises to turn the sky a reddish color; an alternative way of considering the problem is to realize that, as viewed from the Moon, the Sun would appear to be setting (or rising) behind the Earth.

Solar eclipse safety
You should never look directly at the sun, but there are ways to safely observe an eclipse.

It is normally the custom prior to an impending solar eclipse that the mainstream media will provide a variety of warnings and advisories against looking at the Sun with bare eyes, as blindness could ensue. This has given most people the idea that eclipses are dangerous.
It’s the Sun that is dangerous. All the time! The sun constantly emits invisible infrared rays that can damage your eyes. Ordinarily, we have no reason to gaze at the sun. An eclipse gives us a reason, but we shouldn’t.
There are safe ways, however . . .
Acceptable filters for unaided visual solar observations include aluminized Mylar. Some astronomy dealers carry Mylar filter material specially designed for solar observing. Also acceptable is shade 14 arc-welder’s glass, available for just a few dollars at welding supply shops. Of course, it is always a good idea to test your filters and/or observing techniques before eclipse day.
