This is Bob Moler with Ephemeris for Wednesday, June 17th. Today the Sun will be up for 15 hours and 34 minutes, setting at 9:31, and it will rise tomorrow at 5:56. The Moon, half way from last quarter to new, will rise at 4:18 tomorrow morning.

Let’s look for the naked-eye planets for this week. Jupiter now rises before midnight at 11:12 pm in the east-southeast. Saturn will rise 17 minutes later at 11:29 right behind Jupiter. Mars, is stretching its lead left of Saturn and will rise at 1:53 am in the east. Its now down to 83.4 million miles (134.3 million km) away, as the Earth slowly overtakes it at the rate of about 4.3 million miles (7.0 million km) a week. Jupiter and Saturn will be hanging out between Sagittarius and Capricornus this year while Mars is slowing its rapid eastward motion now two constellations over in Pisces. Finally, Venus will rise at 4:51 am in the east-northeast low in the twilight as our new Morning Star.

The event times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
