The Galilean satellite Io will be transiting Jupiter simultaneously with its shadow and that of Europa during the morning of 2012 AUG 29. This will be the final dual shadow transit until 2012 DEC 27.
Since Jupiter is reentering our evening sky, I have resumed daily publication of my four preview graphics related to its Galilean satellites. Two will be appropriately updated to graphically illustrate upcoming shadow transits visible at night from North America. The Galilean satellite event timetable and the pictorial presentation of the satellite arrays visible throughout the night from North America will be updated daily.
The four preview graphics can be found toward the bottom of: www.CurtRenz.com/jupiter
Photos and descriptions of the upcoming dual shadow transit would be welcome additions to this thread.
