Ephemeris: 04/17/2024 – Where have all the planets gone?

April 17, 2024 Comments off

This is Ephemeris for Wednesday, April 17th. Today the Sun will be up for 13 hours and 36 minutes, setting at 8:31, and it will rise tomorrow at 6:52. The Moon, 2 days past first quarter, will set at 5:04 tomorrow morning.

Let’s find out where the naked-eye planets have wandered off to this week, and see what planets are left. Bright Jupiter is very low and in the west. It will set at 10:23 pm. We are getting close to losing Jupiter in the evening sky. Comet 12P/Pons-Brooks is just below-left of it. Observers in the Southern Hemisphere might now get a chance to spot it, but I believe it’s too far gone for us. In the morning, Mars and Saturn will be very close together in the east southeastern sky at 6:30. They will be fighting the bright morning twilight and low altitude then. Saturn will be difficult to see right now in the twilight . It will look fairly different this year and next with its rings nearly edge on to us. They will look more like a line through the planet.
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.

Addendum

The five naked eye planets and Comet Pons-Brooks are located near the Sun
The five naked eye planets and Comet Pons-Brooks are located near the Sun . This image you see the Sun if the Earth had no atmosphere, at solar noon which is about 1:41 PM. Saturn is the farthest planet from the Sun at about 42°. Anything to the right of the Sun is a morning planet, anything to the left is an evening planet. And since Jupiter is above the Sun it can be seen more easily in the evening than can Saturn in he morning, which is below the Sun. Created using Stellarium.

The planet Jupiter shown here much brighter than it will actually appear tonight at 9:30 PM, or about an hour after sunset. It’s altitude will be about 9° above the horizon. Observers south of us will see Jupiter a little bit higher in the sky at the same time period after sunset. Created using Stellarium.

Saturn and Mars as they might be glimpsed early in the morning
Saturn and Mars as they might be glimpsed early in the morning at 6:00 AM, about an hour before sunrise. Saturn is brighter than Mars, however Saturn is dimmer than it normally is mainly because it’s rings are closing and nearly edge on. When the rings are at their most open they contribute more to the brightness of Saturn than the planet does. Created using Stellarium.

None of the planets are good telescopic objects now, due to their low position in the sky, and twilight.

Ephemeris: 04/08/2024 – Solar Eclipse Today!

April 8, 2024 Comments off

This is Ephemeris for Monday, April 8th. Today the Sun will be up for 13 hours and 10 minutes, setting at 8:19, and it will rise tomorrow at 7:08. The Moon is new today, and won’t be visible.

This afternoon there will be a total eclipse of the sun in the United States. But right here it’ll be a very deep partial eclipse, with the moon covering nearly 90% of the sun. For the Grand Traverse Area of Michigan, it will begin at 1:58 PM, mid-eclipse will be at 3:12 PM and the eclipse will end at 4:25 PM. In deep partial eclipses I’ve noticed that the sunlight has a slight yellowish hue. It’s possible effect of the Sun’s edge being cooler than the rest of the disk. Even if it’s cloudy here NASA will broadcast the eclipse from eight points along its route from Texas to Maine. It’s on the Internet on NASA’s YouTube channel, or in an Internet browser type NASA and ECLIPSE. Look for a link for nasa.gov, and you should be able to find out where that feed is. Good Luck!

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.

Ephemeris: 04/03/2024 – Where have the naked-eye planets wandered off to this week?

April 3, 2024 Comments off

This is Ephemeris for Wednesday, April 3rd. Today the Sun will be up for 12 hours and 54 minutes, setting at 8:13, and it will rise tomorrow at 7:17. The Moon, 2 days past last quarter, will rise at 5:33 tomorrow morning.

Let’s find out where the naked-eye planets have wandered off to this week, and see what planets are left. Mercury is now too close to the Sun to be spotted. Bright Jupiter is due west at 8:45 pm or a half hour after sunset. It will set at 11:05 pm. We are getting close to losing Jupiter in the evening sky. Comet 12P/Pons-Brooks is right of and a bit below Jupiter in the evening. Though officially naked-eye brightness, one has to have very good eyes, binoculars or telescope to spot it. In my Wednesday blog posts at bobmoler.wordpress.com I have finder charts. In the morning Mars, and especially Venus and Saturn may be impossible to spot, in the east-southeast in the bright twilight. Mars will rise at 6:10, and will be very low in the east-southeast at 6:45 am.

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.

Jupiter and Mercury as might be seen at 9:00 PM, or nearly three quarters of an hour after sunset, tonight April 3rd 2024 . Also Comet Pons-Brooks is in the same general area of the sky. It is 5th magnitude, and probably not visible without binoculars or a small telescope. Mercury is definiotely not visible wothout a telescope. Created using Stellarium.
A finder chart for Comet Pons-Brooks for the next week
Here is a finder chart for Comet Pons-Brooks for the next week at 9:30 PM. Jupiter is also in the field. The first position is marked with the name, month and day, and the approximate magnitude. The chart shows a comet tail. The tail will probably not be visible visually, however if it is visible, that is the direction it will be pointing. Created using Cartes du Ciel (Sky Charts).

During the solar eclipse on the 8th, during totality, the comet will be located around the 2nd to the last position of its track. However, unless it is obviously noticeable, totality time is too short to use trying to find it. Enjoy the glory of the sun’s corona for the brief time you have.

The Moon, Mars, and Saturn as they might appear about 6:45 in the morning about 1/2 an hour before sunrise low in the east-southeast to southeast. Mars and Saturn are shown brighter than they might appear, so don’t be discouraged if you can’t see them. Created using Stellarium.

This is Ephemeris for Wednesday, March 27th. Today the Sun will be up for 12 hours and 33 minutes, setting at 8:04, and it will rise tomorrow at 7:30. The Moon, 2 days past full, will rise at 10:50 this evening.

Let’s find out where the naked-eye planets have wandered off to this week, and see what planets are left. Mercury is visible in the evening sky shortly after sunset appearing very low in the west. It will be visible for the next few days or so, slowly heading back toward the Sun since this past Sunday. Higher up in the sky is bright Jupiter in the west southwest. It will set at 11:25 pm. Jupiter will be visible in the evening for only about another month or so. In the morning Mars, and especially Venus and Saturn may be impossible to spot, in the east-southeast in the bright twilight. Mars will rise at 6:28, and will be very low in the east-southeast. Comet 12P/Pons-Brooks is below-right of Jupiter in the evening. I’ll have more about it tomorrow.

Ephemeris: 02/16/2024 – The Moon will appear near the Pleiades tonight

February 16, 2024 Comments off

This is Ephemeris for Friday, February 16th. Today the Sun will be up for 10 hours and 29 minutes, setting at 6:12, and it will rise tomorrow at 7:40. The Moon, at first quarter today, will set at 3:03 tomorrow morning.

The moon will pass south, or below, the star cluster called the Pleiades, or Seven Sisters, this afternoon. By this evening the Pleiades will be seen to the lower right of the Moon. However, you will need a pair of binoculars to see them, because the first quarter Moon is quite a bit brighter than the stars of the Pleiades. The moon will again pass the Pleiades in March on the 14th, where the Pleiades will appear above and left of the Moon. And again, on April 11th, where the Moon will pass south of the Pleiades during the day, and the cluster will be to the lower right of the Moon by evening. They will appear closest together in our evening sky on May 8th. Unfortunately, they will be low in the sky in the west at sunset.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EST, UT –5 hours). They may be different for your location.

Addendum

The first quarter Moon and the Pleiades
The first quarter Moon and the Pleiades as they might appear tonight at 8 pm, February 16, 2024, in binoculars. I’ve increased the brightness of the Pleiades which will be pretty much wiped out by the bright moon as far as the naked eye is concerned. However, they should be visible in a pair of binoculars. The brightest of the Pleiades stars, Alcyone, is third magnitude, and the dimmest here would be fifth magnitude Pleione, which is the upper-leftmost star. Created using Stellarium.
