Unusual incident happened on the night of 2 September. Fourth largest moon of Jupiter planets suddenly disappeared.
The position of Jupiter is the brightest shining star in the making it very easy for anyone to see.
Anyone who is directs a small telescope to see Jupiter's fourth moon, also known as Satellite Galiean. Usually at least two or three, often four looks like a small star-like light.
Very rarely is only one month and more rarely seen if not visible at all. Note the first observation of Jupiter without satellites condition it was in 1681.
On this, in the year 1844 in a book entitled "A Cycle of Celestial Objects", William Henry Smyth commented that conjunctions took more than 3000 million years to happen again.
Smyth estimate is excessive. Although the incident "without months of" very rare, but in fact every century there are a dozen more events like this.
Gian Vecenzo "Enzo" Mora of Sequals Italy was the first to make detailed calculations without the moon of Jupiter in 1909. Study of Mora is very thorough and no doubt require a lot of time and all that without the help of modern computers.
Modern research using computer technology, has demonstrated that the count is very accurate mathematical Mora. That are although he was wrong because in 1859, 1898 and 1962 without a moon of Jupiter, too.
