Lunar Eclipse by Steve Rismiller

Partial Lunar Eclipse November 19

Will Be TOTALLY Cool

On the morning of November 19, the Sun, Earth, and Moon align and will give us a lunar eclipse. The Moon probably won’t turn blood red like other lunar eclipses, but it is still one of the greatest shows in the heavens and it will be visible across the entire United States. 

       November 19 (before sunrise)

  •        2:18am Eastern Time: Eclipse Begins
  •        4:02am Eastern Time: Maximum Eclipse
  •        5:47am Eastern Time: Eclipse Ends

The eclipse will begin when shadow of the Earth makes its first appearance on the Moon at 2:18am Eastern Time.  Then the darkness will slowly cover more of the Moon until 4:02am when 97.4% of the lunar surface will be dimmed.  Although not technically a total lunar eclipse, you may still see some colorful shades of gray and hints of pink along the darkest portions of the Moon that is deepest in the Earth’s shadow. The eclipse will end when the Earth’s shadow finally leaves the lunar surface at 5:47am returning the Moon to its full brilliance. 

You don't need any special glasses or equipment to view it.  It is best seen with the naked eye.  And my favorite part is watching when it first starts.  I yell, "There it goes!"  I just love the precision!

If you are clouded out on November 19, the next lunar eclipse will be May 15, 2022.  But try to watch them all.

Dean Regas will be Grand Canyon's Next Astronomer in Residence

The Astronomer in Residence program offers professional and amateur astronomers, educators, scientists, writers, and visual and performing artists the opportunity to practice and share their discipline under one of the most pristine night skies in the United States.

As the next Grand Canyon Astronomer in Residence, renowned educator, author, and astronomy expert Dean Regas will live and work at the South Rim of Grand Canyon National Park from November 16 to December 8, 2021.

The program is modeled after the Artist in Residence program popular in parks across the country. The park hosts a chosen applicant on-site for a short-term residency; the resident, in turn, completes projects in their medium through direct experience of the park’s resources. Some amount of finished product is donated to the park and some amount of visitor outreach is agreed upon based on the nature of the residency. The difference is that this program focuses on night skies, astronomy, and the various disciplines studying natural darkness.

Cincinnati Libraries to Loan Telescopes

Cincinnati Observatory Astronomer Dean Regas is partnering with the Cincinnati and Hamilton County Libraries to offer the stars to library patrons.  Telescopes may be checked out from certain branch libraries starting this month.

Regas donated 10 telescopes to the libraries so that patrons can borrow them like checking out a book.  “My hope is that people will be inspired by their views through the telescopes and the universe,” Regas said.  

With just your library card you can sign up to reserve a telescope for a three-week period.  The telescopes are small but powerful and can show the craters on the Moon, the planets, and stars and star clusters up close. 

“I wished I had this at my local library growing up,” Regas said.  “Everyone should be able to explore the universe like this with friends and family.”

Partial Solar Eclipse 

Thursday June 10

I chased the eclipse in search of clear skies and better views and traveled to Mackinaw City, Michigan.  Luckily the clouds stayed away and I was able to get capture this video of the partially eclipsed Sun just above Lake Huron at sunrise. 

It is so awe inspiring and such an amazing sight to see the Moon block out part of the Sun.  The next solar eclipses visible from the United States will be October 14, 2023 and April 8 2024.  Mark your calendars and don't miss them!

Moon + Venus Conjunction

The slimmest crescent Moon was about 1 degree from the planet Venus on the evening of Wednesday May 12, 2021. And astronomer Dean Regas was there to capture it. The video was taken with a camera phone attached to a small portable telescope.

Happy Birthday Mitchel Telescope!

The Cincinnati Observatory's main telescope turned 175 years old last April 14 and we'd like to look back at how Astronomer Dean Regas gave a virtual tour of the scope last year.  So wish us a happy 176th birthday today!

Mae Among the Stars

Dean reads the children's book about astronaut Mae Jemison and her dream to become an astronaut.  Thank you to the Cincinnati Museum Center for including this in their Story Tree Time program. 

Jupiter and Saturn Come Together

On the nights of December 20, 21, and 22 the largest planets in our solar system, Jupiter and Saturn, appeared closer together in the sky than they have since 1623.  In fact they were so close that you could see the two planets in a telescope at the same time!  

To the right is video captured by Astronomer Dean Regas through the Cincinnati Observatory's 175 year old telescope on December 21.

100 Things to See in the Night Sky

Dean takes you inside his new book, 100 Things to See in the Night Sky, Expanded Edition and then shares his tips to observing the Sun safely and finding a lot of planets, stars, and constellations this week.
