A shallow partial lunar eclipse is on faucet for the night time of September seventeenth/18th.
The eclipse is a slight one to make sure, however might be noticeable because the northwestern limb of the Moon simply slips previous the darkish internal umbral shadow of the Earth.
The eclipse is simply over 8% partial at its most, that means the Full Moon will look slightly ‘smushed’ on one facet at mid-eclipse.
Timing and Visibility
The eclipse might be seen in its entirety across the Atlantic Ocean area, together with western Africa and Europe, japanese North America, and all of South America.
Japanese 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) part 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.
All the penumbral part of the eclipse begins at 00:41 UT/8:41PM EDT, and runs about 4 hours and 6 minutes in length.
A Sophisticated Celestial Affair
That is additionally a posh 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 seemingly result in cries of a ‘ Supermoon eclipse’ throughout ye ‘ole internet. 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 referred to as the Harvest Moon.
Not solely did the illumination from the Full Moon give farmers within the pre-industrial period just a few additional 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 night time to the subsequent, rising solely barely later.
I keep in mind rising up selecting potatoes in Northern Maine in September, working our means dwelling on foot underneath 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 night time on the appointed time. Fashionable telephones zoomed in will produce a transparent picture, as will a telephone digital camera aimed by way of 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 part. Then, the Moon could appear to have a little bit of a tea-colored tint.
In direction of the partial part, the ragged umbral shadow of the Earth will simply brush the Moon. The curve of the shadow solid by the Earth will grow 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 area as nicely. A lot 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 in the future, human astronauts will stand on the Moon and witness this occasion.
Tales of the Saros
Eclipses (lunar or photo voltaic) happen in teams referred to as saroses, with members spaced 18.04 years (223 synodic months) aside. A number of saroses are energetic at any given time.
That is eclipse member 52 of 74 for lunar saros collection 118, that means this cycle is previous its prime on its means out. Lunar saros 118 started waaaaay again on March 2nd, 1105. This saros produced its first complete lunar eclipse on August 22nd, 1393, and remaining one on June 22nd, 1880.
In case 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 collection (a barely perceptible penumbral eclipse) happens on… (mark your calendars) Might 7th, 2403.
This marks the beginning of the remaining eclipse season of 2024. That is book-ended by an annular photo voltaic eclipse two weeks any longer 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, be sure you give this remaining lunar eclipse of 2024 a glance Tuesday night time.
