Abstract:
The main topic of this paper is the observation of the mutual phenomena of the largest Jovian satellites (the Galilean satellites). The paper begins with a description of the Jovian planetary system, Jupiter and its satellites, followed by information regarding mutual phenomena, what they are and how they are produced.Personal contribution consists in a series of telescopic observations of the Jovian satellites mutual phenomena, between December 2014 and September 2015. The observation technique, data processing and analysis as well as the results of the observations are described within.The planet Jupiter has the largest number of satellites, most of which are small in size, out of all the planets in our solar system. Out of the 67 Jovian satellites, we will focus on the four largest, also known as the Galilean moons: Io, Europa, Ganymede and Callisto, as these are located on the planet’s ecliptic plane. As Jupiter passes through its orbital points, the planet’s equatorial line is facing Earth, rendering visible any satellites orbiting its ecliptic plane. At this time, mutual phenomena of Jovian satellites will occur.
