We observe the Jupiter's galilean moons.

 

1. What we need?

To observe the Jupiter's galilean moons it is enough to have the binocular with the tenfold power, but, of course, it may also be the telescope. We need the notebook or the exercise book where we will note the results of our observations and something to write down, some pencils are recommended. The lantern with the red filter and the watch will be useful.

 

2. What we will observe?

Making the illustrations, showing the changes of the position of Jupiter's moon with regard to the planet and each other is the aim of our observations.

3. How we observe the Jupiter's galilean moons?

a) Firstly, we have to note the date and the moment of observation. Recommended is the Julian Date or the Universal Time - UT.

b) Then, we describe the weather conditions and seeing (condition of the atmosphere), which have an influence on the quality of the view. That information is important, because it helps to determine the reliability of the results of the observation.

c) Next, we note the parameters of our instrument and the geographic coordinates of the place, where we observe.

d) Subsequently we start the real observation. After finding the Jupiter and the four moons we sketch their positions, taking a diameter of the Jupiter's shield as our unit.

 

 

And that's all!

Our observations we repeat (as long as possible) every night. After some time we will gain the illustration of the motion of the Jupiter's satellites around the planet.
 
Those observations have not a big scientific value, but they may give a lot of the satisfaction and pleasure.

 

Good luck! :)
