Celestial coordinates are a reference system used to define the positions of objects on the celestial sphere.There are two main coordinate systems in use: The equatorial coordinate system is far the most common for astronomical observations, and is basically an extension of the latitude and longitude coordinate system used on Earth. defining a right ascension, a declination and an epoch The Observer's Book of Wild Animals of the British Isles. 72 Illustrations in Colour and Black & White. 69 Species Described.

Astronomers make use of the ``Observer's Triangle'' when converting angles to distances. In the illustration below, the apparent size is the angular diameter of a planet (or any object), and if you know the distance to the planet, then trigonometry (yes, trigonometry) tells you the actual linear size of the planet: The Kansas Astronomical Observers is an organization which actively pursues the aesthetic and intellectual enjoyment of astronomy through observing, study, The purpose of the Observer s Challenge is to encourage the pursuit of visual observing. It s open to everyone that s interested, and if you re able to contribute notes, and/or drawings, we ll be happy to include them in our monthly summary. We also accept digital imaging.

AAVSO: New Editor for Journal of Variable Star Astronomy Press Release From: American Association of Variable Star Observers (AAVSO) If the star is moving relative to the observer, the lines will be shifted (because of the Doppler Fizeau effect) an amount A/A = V/c where A is the wavelength, V, Thirty years ago, astronomers witnessed a near stellar explosion, but it wasn't the first.

The celestial meridian is the line on the celestial sphere joining the observer s zenith (i.e. The point directly overhead) with the north and south celestial poles. Study Astronomy Online at Swinburne University Our club, the Astronomical Society of Harrisburg, has a dark sky site in that area. I don't have the details here at work. I'll respond again later The number of degrees the celestial pole is above the horizon is equal to the latitude of the observer. Fortunately, for those in the northern L.F.
