Transit shadows on Jupiter in the night from Saturday
For a little more than 2 hours in the night from Saturday 17 to Sunday, May 18, the shadows of Io and Callisto, Jupiter’s moons will be visible on the giant planet.
On the night of Saturday 17 to Sunday, May 18, 2014, from 23 h 21 min and 2 h 7 min, the satellites Io and Callisto project jointly their shadows on Jupiter. This is the part that takes the double transit, 10 min after midnight.
The planet is then at ten degrees above the horizon west-northwest. An instrument of 200 mm diameter and a magnification of 100 to 200 times is essential to the success of direct observation and unequivocal phenomenon.
