A shallow partial lunar eclipse is on faucet for the evening of September seventeenth/18th.
The eclipse is a slight one to make sure, however shall be noticeable because the northwestern limb of the Moon simply slips previous the darkish inside umbral shadow of the Earth.
The eclipse is simply over 8% partial at its most, which means the Full Moon will look slightly ‘smushed’ on one facet at mid-eclipse.
Timing and Visibility
The eclipse shall be seen in its entirety across the Atlantic Ocean area, together with western Africa and Europe, jap North America, and all of South America.
Jap Europe and Africa will see the eclipse in progress at moonset in direction of dawn, whereas western North America will see the eclipse already underway at moonrise/sundown.
The umbral (partial) section of the eclipse lasts not fairly 63 minutes in length, and is centered on 2:45 Common Time (UT) Sept 18th/10:45 PM U.S. East Coast Time (EDT) on the night of Tuesday, September 17th.
The complete penumbral section of the eclipse begins at 00:41 UT/8:41PM EDT, and runs about 4 hours and 6 minutes in length.
A Difficult Celestial Affair
That is additionally a fancy occasion, earlier than and after the eclipse. First up, the Moon occults (passes in entrance of) the planet Saturn for western North America, simply over 15 hours prior.
Then, the Moon reaches perigee (its closest level to the Earth) simply 10 hours after the eclipse. It will doubtless result in cries of a ‘ Supermoon eclipse’ throughout ye ‘ole net. Do not buy into any purported ‘ Blood Moon‘ hype; the Moon will not go far sufficient into the umbral shadow of the Earth to show pink.
Lastly, the Moon additionally occults Neptune for North America simply over 5 hours after the eclipse, a difficult occasion certainly.
The September Moon nearest the Equinox (which falls on Sunday, September 22nd, for 2024) is also called the Harvest Moon.
Not solely did the illumination from the Full Moon give farmers within the pre-industrial period just a few further hours to get the harvest in, however the angle of the ecliptic is shallow sufficient in September that the Moon appears to linger from one evening to the following, rising solely barely later.
I keep in mind rising up choosing potatoes in Northern Maine in September, working our manner dwelling on foot beneath the sunshine of the Harvest Moon.
Catching This Week’s Partial Lunar Eclipse
Observing and imaging the eclipse is so simple as following the Full Moon Tuesday evening on the appointed time. Fashionable telephones zoomed in will produce a transparent picture, as will a cellphone digital camera aimed via the eyepiece of a telescope.
You in all probability will not discover something is amiss with the eclipse till about half-hour into the penumbral section. Then, the Moon could appear to have a little bit of a tea-colored tint.
In direction of the partial section, the ragged umbral shadow of the Earth will simply brush the Moon. The curve of the shadow forged by the Earth will turn out to be obvious, visible proof that our honest planet is certainly spherical.
Cloud cowl prospects for the contiguous United States appear to favor the central and southern U.S. round eclipse time:

The Partial Lunar Eclipse…As Seen From Area
The spectacle extends out into house as effectively. Many of the Earthward face of the Moon will expertise a partial photo voltaic eclipse, besides the very northwestern limb, which is able to see a complete photo voltaic eclipse. Maybe sooner or later, human astronauts will stand on the Moon and witness this occasion.
Tales of the Saros
Eclipses (lunar or photo voltaic) happen in teams often known as saroses, with members spaced 18.04 years (223 synodic months) aside. A number of saroses are lively at any given time.
That is eclipse member 52 of 74 for lunar saros sequence 118, which means this cycle is previous its prime on its manner out. Lunar saros 118 started waaaaay again on March 2nd, 1105. This saros produced its first whole lunar eclipse on August 22nd, 1393, and last one on June 22nd, 1880.
When you caught the September 7th, 2006 partial lunar eclipse centered over the Indian Ocean area, you caught the final member of this saros cycle. The ultimate member of saros sequence (a barely perceptible penumbral eclipse) happens on… (mark your calendars) Could 7th, 2403.
This marks the beginning of the last eclipse season of 2024. That is book-ended by an annular photo voltaic eclipse two weeks any more October 2nd. This occasion spans Easter Island within the South Pacific, and the southern tip of South America.
The subsequent lunar eclipse is a complete lunar eclipse on March 13-14th 2025 favoring the Americas. This ends the present ongoing ‘lunar eclipse drought,’ because the final one occurred on November 8th, 2022.
If skies are clear, make sure you give this last lunar eclipse of 2024 a glance Tuesday evening.
