06/22/2022 – Ephemeris – Let’s search for the naked-eye planets for this week

June 22, 2022 Comments off

This is Ephemeris for Wednesday, June 22nd. Today the Sun will be up for 15 hours and 34 minutes, setting at 9:32, and it will rise tomorrow at 5:57. The Moon, 2 days past last quarter, will rise at 2:48 tomorrow morning.

Let’s search for the naked-eye planets for this week. All the naked-eye planets are in the morning sky, although Mercury may be too close to the Sun to be seen. It might just be visible low in the east-northeast after 5. That’s at least for those as far north as we are. At 5 am tomorrow the planets will be spread out from Mercury, actually invisible, near the horizon, brilliant Venus low in the east-northeast to Saturn higher in the south. To the right of Venus, tomorrow morning, stretching from east to southeast, will be the Moon, Mars and Jupiter. Mars is quite a bit dimmer than Jupiter. All will be in line sloping to the upper right with Saturn all by its lonesome in the south. The naked-eye planets are arranged in the morning sky, in the same order as their distances from the Sun.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT – 4 hours). They may be different for your location.

Update on the Tau Herculid meteor shower of May 31st.

The meteor shower was rather weak. I saw one during an hour and a half of observing, slowly moving over the Big Dipper. The sky was “clear”, but there was a haze to it. It definitely wasn’t crystal clear. I’ve heard from others who had a bit more success.

To the right of Venus, tomorrow morning, will be the thin crescent Moon. Farther right is the quite bright Jupiter. Just to the right of Jupiter will be the dimmest of the 4, Mars, which is closing on Jupiter. The two will seem to pass each other on Sunday.

This is Ephemeris for Wednesday, May 18th. Today the Sun will be up for 14 hours and 56 minutes, setting at 9:07, and it will rise tomorrow at 6:10. The Moon, 2 days past full, will rise at 12:43 tomorrow morning.

Let’s search for the naked-eye planets for this week. The one bright planet in the evening sky, Mercury, will pass between us and the Sun this Saturday to join the rest of the naked-eye planets in the morning sky. So that’s where the planet action is. At 5:15 am tomorrow, the planets will be spread out from brilliant Venus low in the east to Saturn higher in the southeast. Venus may be missed at that time, but may be up sufficiently by 5:30. To the right of Venus is the quite bright Jupiter. Farther right will be the dimmest of the 4, Mars, which is closing on Jupiter. The two will seem to pass each other on the 29th of this month. All will be in line, sloping to the upper right. They are still quite a sight to behold in the morning twilight.

Let’s search for the naked-eye planets for this week. The one bright planet in the evening sky, Mercury, is now too dim and close to the Sun to be seen, so the only planet action is in the morning sky where the other 4 naked-eye planets are. At 5:15 am tomorrow the planets will be spread out low from the east to southeast with brilliant Venus lowest and due east to Saturn almost exactly in the southeast. Venus may be missed at that time, but may be up sufficiently by 5:30. To the right of Venus is the quite bright Jupiter. Farther right will be the dimmest of the four, Mars. Farther to the right will be Saturn. All will be in A sloping to the upper right. They are still quite a sight to behold in the morning twilight.

05/04/2022 – Ephemeris – Let’s search for the naked-eye planets for this week

May 4, 2022 Comments off

This is Ephemeris for Wednesday, May 4th. Today the Sun will be up for 14 hours and 23 minutes, setting at 8:51, and it will rise tomorrow at 6:27. The Moon, halfway from new to first quarter, will set at 1:03 tomorrow morning.

Let’s search for the naked-eye planets for this week. There is one bright planet in the evening sky. Mercury may be spotted around and after 10 this evening very low in the west-northwest and be visible for the next half hour or so before it sets at 10:40 pm. After that, the planet action shifts to the morning sky. The other 4 naked-eye planets are there. By 5:30 or 5:45 am, the planets will be spread out low from the east to southeast with brilliant Venus lowest in the east, higher and right is Jupiter. Dim Mars will be farther to the right and a bit above Jupiter, while brighter Saturn will be even farther right and above Mars. All four will have risen by 5 am, but it will take a very low eastern horizon to pick them all up at that time.

05/02/2022 – Ephemeris – The Moon and Mercury together where we can see them

May 2, 2022 Comments off

This is Bob Moler with Ephemeris for Monday, May 2nd. Today the Sun will be up for 14 hours and 17 minutes, setting at 8:49, and it will rise tomorrow at 6:29. The Moon, 2 days past new, will set at 11:02 this evening.

The two-day-old thin sliver of a Moon will be left and above Mercury this evening. About the best time to spot them is between 9:30 and 10:15 pm, low in the western sky. They will be seen in the west-northwest. As we move through the week, the Moon will move away from Mercury to the east, while Mercury heads back toward the Sun and, dimming as it goes. Mercury is the closest planet to the Sun and averages 40 percent of the Earth’s distance from the Sun, so it is never seen at our northerly latitude outside of twilight. Mercury has the most elliptical orbit of the major planets. And it happens that at the best times to see Mercury, on spring evenings and autumn mornings, Mercury is at its nearest to the Sun. Southern Hemisphere observers get a better look at it because their best observing times are when Mercury is farthest from the Sun.

04/26/2022 – Ephemeris – Tomorrow is the Moon’s final stop in passing the parade of morning planets

April 26, 2022 Comments off

This is Bob Moler with Ephemeris for Tuesday, April 26th. Today the Sun will be up for 14 hours and 1 minute, setting at 8:41, and it will rise tomorrow at 6:38. The Moon, 3 days past last quarter, will rise at 5:37 tomorrow morning.

Also, tomorrow morning, the Moon will conclude its sweep under the four bright planets of the morning sky by being seen below the left-most and lowest of the four, Jupiter. With nearby Venus, it makes a small right triangle The other planets in order to the right of Jupiter are Venus, Mars and finally Saturn. Jupiter and Venus are appearing to get closer to each other every day now. They will cross paths in conjunction this Saturday. Venus is slowly retreating back and around behind the Sun. Jupiter now appears to be moving away from the Sun. Both, however, are still moving eastward against the stars, it’s just that Venus is moving faster. Next month, when the Moon passes by these planets, they will be a different order.
