Eclipse Report from Ohio

 I am thankful we were in the path of totality and that there were only very light thin clouds, and that I got to see this rare event.

On the other hand, I have had many far more interesting, beautiful and photographic sunsets down by the lake shore.

What I found most interesting about the experience is its three-dimensional quality. One really had the sense of a physical body, the Moon, passing in front of the Sun. 

My iphone photograph:




The most enjoyable part was getting out my old telescope which I haven't used much since I was in high school. I did a practice set up on Sunday afternoon which helped much.


The telescope is a 2.4" refractor. Unfortunately my parents could only afford an altazimuth mount which means that one has to move the telescope in two directions. An equatorial mount aligns the telescope with the North Pole so that one only has to move the telescope in one direction as the earth rotates. 

Fortunately I have a lot of old carboard boxes. One just the right height to project the sun's image into, and the other put around the eyepiece to shade the larger box from ambient light.



 
Inside the large box is a white piece of cardboard duck taped to a flap of the box which unfortunately had to be hand-held in place.




Below is the telescope on eclipse day about halfway toward totality. Notice the small finder telescope on this side of the main telescope. Both cast shadows on the small box which shields the larger box into which the sun's image is being projected. Inside the dark shadow of the small telescope is a bright image of the partially eclipse Sun.




Here is a large picture of the finder shadow with the partially eclipsed Sun inside. Now the earth is constantly moving as the image of the Sun moves outside the shadow on the outside of this box, the image inside will also be moving out. The trick is to always constantly readjust the telescope to keep the Sun centered in the shadow of the finder telescope.



Below is the control center of the telescope.

The arrows indicate the wing nuts that control the up and down (top arrow) and right-left motions of the telescope. Loosing the wing nuts permits large movements to aim the telescope at the Sun. 

Once the wing nuts are tightened fine movement control is made by turning the two knobs inside the circle.  Since the Sun's apparent movement in the sky over an hour is quite large both the wing nuts and the fine controls have to be used in alternation.




Unfortunately, since someone (Betty) had to hold the cardboard in place in the large box, and someone (myself) had to be at the controls most of the time, I did not get many pictures of the images inside the box.  Those, like the large collection of sunset photographs might have made the event more exciting and memorable.

A SUPER SPREADER EVENT?

They were talking about a huge number of people coming into the Cleveland area with potential traffic jams afterward. Maybe that happened on the Interstates. What happened locally was the everyone stayed home to view the eclipse.  Actually, there was so little traffic that a silence descended upon the event much like during the pandemic. 

There was no school of Monday. Lakeland Community College closed its campus as did our parish with its school. Some communities did use their school stadium for a community event, however some restricted the unpaid admission to hometown residents.

The pandemic began in Cleveland before lockdown when a bunch of Republicans came back from a CPAC meeting in DC which had been a super spreader event. That continued a pattern during the pandemic of downtown Cleveland becoming infected which spread to the suburbs. Maybe that will happen again with this event? 

Of course if it happens the general population will not notice it, it will only be noticed in the spike of Covid related admissions among the elderly and immunocompromised.

  1. Jack that's neat that you were able to experience totality. Also it was an ingenious set-up with your telescope.
    I have seen comments by other people who were in the totality zone that there was a noticeable temperature drop. Did you notice it getting cooler?

  2. Looks like you had fun, Jack! We got free glasses from the local library. Totally clear day. Raber came out a couple times for a looky loo, but was engrossed in tax forms. We were at 98%. Noticeably darker, cooler, breezy. But no interesting shadow effects this time.

    Some evangelicals were predicting the Rapture with Jesus set to show up in southern Illinois where the paths from the eclipse seven years ago intersected with Monday's event. The East Coast earthquake just before the eclipse was a sure sign!

    1. Oops, meant to post here: PS on covid spread: Seems like good news for Ohio, as the Wash Post reports covid is declining in most places, at least for the season. Plus outdoor events, even in stadiums, might be far less spread-y than in indoor conference centers. A friend asked us to go to Luna Pier, but we didn't want to fight traffic. He said I75 was backed up by 10 a.m., but the city park wasn't too crazy.

    My eclipse photographs. I built a solar tracker like Jack's setup but had spotting telescope and box mounted on same arm. Used sticks for elevation and moved base for azimuth. Hole in box was used as a finder scope.
    Used my Iphone when eclipse went total. One short video when sun re-emerged. You can see some red. Apparently that's from a cooler upper layer in the sun's photosphere. Thought my expedition was toast when the clouds moved in but they parted enough and lent more beauty and strangeness to the photos. I used my iPhone when the eclipse went total. Whole experience was amazing. The ten degree drop in temperature, the 360 degree horizon aglow as if dawn would come from everywhere. And some dog barking in disapproval of it all. Worth it even with the doubled travel time (6.5 hours) home due to the eclipse watchers.
    Compliments to Jack on his setup. You have some optical engineer in you.

    1. I couldn't get to your photos, but enjoyed yr report! We're you able to see solar flares at totality? Maybe only the big scopes could pick that up. I tried looking at the eclipse thru my Celestron binoculars with the lenses covered with glasses, but I didn't see flares, and it was too awkward.

      I didn't notice change in bird activity. The cats just slept thru it. They also slept thru the little earthquakelet we had about 10 years ago. Half the time I can't even find them. They rematerialize from whatever point on the time-space continuum they've been visiting only if they hear me shake their treat bag or roll out the yoga mat. They think the mat is for them.

    2. Nice photos, Stanley. Thanks for sharing. I'm glad you got to see the totality. Did you manage to find a hotel room that wasn't booked, or did you just do all the driving in one day?

  5. Katherine, I did rent a room Sunday night at a fisherman motel but only smoking rooms. I guess fisherman need to smoke to cancel out all that fresh air. I drove home after the eclipse. 6.5 hours of driving instead of the usual 3.25.
    Jean, binoculars usually run about 8X and not enough to resolve the prominences. But the ring of fire can be seen.

  6. Jean, It seems that red dot visible just before totality ended might have been a prominence. I may try to post some pictures and a video so you can see it but I have to figure out how to get from point A to point Z.

    1. Neato! We were only at about 97 percent, so we didn't really get any spectacular visual effects. Was still fun. Plus didn't have to leave my front yard. We have had some crystal clear days with very low humidity, so using the binoculars nights has been fun.

    2. Red dots = plasma eruptions, not solar flares. Love this stuff! More here: https://www.livescience.com/space/the-sun/no-you-didnt-see-a-solar-flare-during-the-total-eclipse-but-you-may-have-seen-something-just-as-special

  7. If you have the time and money here are your options in the next few years.

    1. Total solar eclipse of 2026 – August 12, 2026 the path of totality will pass over Greenland, western Iceland and northern Spain. The place to experience maximum totality will be on a cruise ship off the coast of Reykjavik, Iceland. The chances of a clear sky are much higher in northern Spain, but the eclipse will be much lower, so sight lines will be key. From the Spanish island of Mallorca, it will even be possible to see a "sunset totality" featuring a golden corona (as long as there are clear skies).

    2. Total solar eclipse of 2027 The next one is on Aug. 2, 2027, with Luxor, Egypt, destined for a clear view of 6 minutes, 23 seconds of totality. Other options include southern Spain; Gibraltar; Tangier, Morocco; Tunisia's Kerkennah Islands; and Jeddah and Mecca, Saudi Arabia.

    3. Total solar eclipse of 2028 – July 22, 2028 This solar eclipse — the second of five in 15 years for Australia — will be visible from remote locations such as the Bungle Bungles and Karlu Karlu (Devils Marbles) in Western Australia and the Northern Territory, respectively, as well as Dubbo, the Blue Mountains and Sydney, where observers will get to witness 3 minutes, 48 seconds of totality. The South Island of New Zealand — including Milford Sound, Queenstown and Dunedin — will also experience totality close to sunset.

    1. Well I won't have the money, but if I did, my choice would be the one in 2026, on the island of Mallorca, to see the "sunset totality".

  8. We had free dark glasses from the local library. I dashed into the front yard for a few seconds several times between work calls. We were at something like 94% of totality in Chicago. Didn't get as dark as we were hoping.

    Jack, during a prior eclipse, when the kids were at home, we did a poor man's version of your viewer - I think we used a shoebox and a pinhole. It worked pretty great.

  9. My daughter's elementary school watched the eclipse (or 94% of it). Apparently the school district came up with eclipse glasses for the entire school. She said that, after returning to the classroom, the kids were so excited about it that she had to skip their writing lesson so they could talk more about the experience.

    1. That's so great they were interested! If her kids wanted to donate their eclipse glasses, she could get them to write little notes to future recipients about how to be careful about viewing, what they saw through the glasses, and how they felt about it. Then have them read their noted before sending them off. (Yes, I still miss teaching a lot!)

  10. Anybody who wants to recycle or donate eclipse glasses can do by mailing to your state's collection center for Astronomers without Borders: https://astronomerswithoutborders.org/programs/solar-glasses-distribution

  11. My eclipse story was that our area was only about 70% and we didn't make an effort to find some eclipse glasses. So my plan was just to stay inside. But one of my friends phoned me that her cat was sick and she needed help loading her into a carrier for her vet appointment. Which was in the midst of the eclipse. I had heard so much about the possibility of eye damage that I asked her if she could get the appointment moved later. So she called the vet office, but they didn't have any openings later. The vet tech said, "Tell your friend to just not look at the sun, she'll be fine." Which I suppose I knew, I was just being too hyper. So I went over and we got the cat loaded ( I suppose she'll hate me now!) and took her to the vet. And my friend gave me her eclipse glasses and said "Have a look." I did manage to see the little crescent shape, and it was kind of neat, even though we didn't see much darkening. I took the glasses home so my husband could also have a look.

    1. Yes, the cat is doing better. She had a urinary tract infection, and they gave her an antibiotic shot. It's long acting, and my friend won't have to give her pills. Getting cats to take pills, not fun!

    2. I don't recall us ever succeeding in getting any of our cats, ever, to actually swallow a single pill.

    3. Glad cat is ok. Our cats vary on their cooperativeness with meds. Edgar would just lie there and purr while you dumped his pain meds down his throat. Geoffrey would eat anything ground up in food. Sadly, the boys have died. Flora gives us one try at a pill and then turns into a Tasmanian devil. We "inherited" Daisy after Mom died, and she is even worse. Thank heavens for those long-lasting shot antibiotics.

    4. I once got a liquid med from the vet for one of our cats, thinking I could put it in cream and he would drink it down. Nah. He took one sip and turned his back to me for the rest of the day. Nothing like getting cancelled by a cat!

      Delete
    5. Haha! Now that you mention it, my whole life has been spent getting cat-cancelled. Daisy always sniffs her food and gives us one if her "whatever you're trying to pull here, I'm on to you" looks before she eats it. Raber, even after 40 years of my dragging home cats, still expects gratitude from them, poor man.
