What is a Penumbral Lunar Eclipse? | Full Buck Moon 2020

A penumbral lunar eclipse occurs on the evening of Saturday, July 4th, for most of the Western Hemisphere. In this kind of lunar eclipse, the Moon only reaches the Earth’s outer shadow, so it doesn’t darken very much at all, and it won't look red like a total lunar eclipse.
As seen from Flagstaff, Arizona, the Moon will rise on July 4th at 7:41 pm PDT. The penumbral lunar eclipse begins at 8:07pm, when the Moon begins to enter the penumbra. In this eclipse, the Moon never makes it all the way into the penumbra. Maximum eclipse is at 9:30pm. The Moon leaves the penumbra at 10:52pm, and the penumbral eclipse ends.
Join Lowell Observatory at 8pm PDT on Saturday, July 4th, for a live stream of this penumbral lunar eclipse: • Penumbral Lunar Eclips... .

Great explanation and visuals. Thank you.

Thank you for the descriptive details. Many are anxious for the penumbral eclipse, not realizing the moon will barely darken. Still, we love viewing the Moon. Earth's little buddy.

Nice presentation. Thank you.

[@LowellObservatory1894]

Glad you liked it!

I was at Torch lake in Northern Michigan at 45 degrees latitude, 45th parallel and it was phenomenal 😮

[@prsnheretodo]

Very well explained, no complication. Thank you!

[@ShlisaShell]

Dang. I made one of my best Moon time lapses that night but I think I did it too late in the evening. Wish I had known. I love making moon time lapses. Thanks

[@sajalkrr]

Awesome explanation

"Syzygy"!! Great X-files episode..lol I stayed up and tried to watch, but really didn't notice too much

[@eunicekaranja3231]

This video is epic

[@HerRoyalKateness]

The cautious, contracting Capricorn moon energy will haunt us for months like a dark Edgar Allen Poe poem.

Classic presentation

[@johnsinger9156]

She speaks of the eclipse as seen from Arizona which is on Mountain Daylight Time - two hours behind those on the east coast. If it starts at 11:PM EDT and goes to !:PM I assume the optimum time to view the effect of the full eclipse would be around midnight EDT for those near the east coast, 11:PM for those on Central Time and 10:PM for the those on Pacific Time.

[@LowellObservatory1894]

Hi John, Arizona doesn't observe Daylight Savings, so we're currently the same as Pacific Daylight Time. For the East Coast, look at the second set of times at 0:07 in the video. Maximum eclipse is at 12:30am on the East Coast. Wishing you clear skies!

[@johnsinger9156]

Lowell Observatory; It looks like we'll have clear skies here tonight (Georgia) Thanks so much for taking time to give the heads up!

@@LowellObservatory1894 The moon is turning like a clock and for some reason some people think it is normal. The terminator line should be vertical except for libration.. kzbin.info/www/bejne/pJu8hJ1qp699q68

Nice

[@jacoboflaherty5282]

I heard it started at 11

[@pamelagardnerisenhour9933]

I was at Casper Wyoming August 21st 2017 during the TOTAL SOLAR ECLIPSE OF THE SUN IN TOTALITY. Next TOTAL SOLAR ECLIPSE OF THE SUN is southern America April 8th 2024. Take a train to Dallas Ft Worth which is in the path OF THE TOTAL SOLAR ECLIPSE OF THE SUN in TOTALITY. Party train

Very good video! Only one thing....you may want to state which time zone you're in. Because here on the east coast, it begins at 11:07pm.

[@jae15.]

I hope this doesn’t come off as snarky, but she clearly states she’s talking about Flagstaff, Arizona when she starts mentioning the times, and at the end she says “join us at 8pm pacific.” It seemed fairly obvious to me, but, to anyone who sees this comment and is also confused or wasn’t paying attention, she’s talking about Arizona’s time zone, which is talking about Pacific Time (UTC−08:00).

[@jborrelli34]

I still don’t fully understand the difference between this and the Moons regular phases?

[@rorysnow7937]

The moons phases have nothing to do with Earth’s shadow

[@Frankyouknow]

There was no penumbra the model failed big time.

[@elo5449]

Right the second you started with a globe earth you failed!

[@chasedagley775]

Bitch what?

[@filiplinhart9034]

Penumbral eclipses are not spectacular and often almost invisible, the only interest is to take a photo before (or after) the eclipse and another one at mid-eclipse (with exactly same exposure time) and to put the 2 pictures together.

[@colleenpenny6304]

Can't be the reason. Not possible to occur like that as earth is FLAT
