Ephemeris: 08/02/2023 – Let’s find out where the naked-eye planets have wandered off to this week
This is Bob Moler with Ephemeris for Wednesday, August 2nd. Today the Sun will be up for 14 hours and 37 minutes, setting at 9:07, and it will rise tomorrow at 6:31. The Moon, 1 day past full, will rise at 10:15 this evening.
Let’s find out where the naked-eye planets have wandered off to this week. Venus is gone, setting too close to sunset. It will pass between the Earth and the Sun on the 13th, and be visible before sunrise by the end of the month. Mars and Mercury, though technically in the evening sky and like Venus, appear too close to the Sun to be spotted. Mars will pass behind the Sun in November. The other two naked eye planets are in the morning sky. Appearing at 5:45 am, which is roughly 45 minutes before sunrise, tomorrow morning, Jupiter will be high in the southeast, while Saturn will be lower in the southwest. And tomorrow morning Saturn will be just above the bright waning gibbous Moon.

Tomorrow, the Sleeping Bear Dunes National Lakeshore and the Grand Traverse Astronomical Society will host a Sun and Star Party at the Dune Climb area of the park. There will be a solar viewing period from 5 pm to about 7 pm. The society has two hydrogen alpha solar telescopes to view the Sun’s chromosphere and prominences. Plus, some members also have solar scopes and white light filtered telescopes to view sunspots on the face of the Sun. Night viewing will start at 9 pm with the Moon featured, along with the brighter telescopic wonders of summer. The park rangers will leave at 11 pm, but society members will stay later to get a good view of Saturn as it moves higher in the sky. All this will happen only if clouds permit.
