Using our box pinhole projector about 18 minutes before totality, in addition to the one intended image of the sun from our nail-hole in an index card, a couple very small holes in the box have also produced two more images of the crescent sun over on the right. Photo by Eric Hadley-Ives. |

Using a box pinhole projector one can see the shape of the crescent sun. |
Any patch of light squeezed through a sufficiently small hole will form a pattern that takes the shape of the crescent sun; here we are holding a mesh above some paper and observing the many crescent shapes, just about a minute or two before totality. |
Whether you look at the sun through a solar filter or see the image projected in a box pinhole projector, the same crescent appears. |

Just seconds before totality, only a thin sliver of sun remains unobscured by the moon. It was still far too bright to observe directly, so this photo is taken through a solar filter.

In the last twenty seconds before totality the change in light from an eerie dimness to night-time darkness suddenly comes over the land. While it is as dark as night on the land, in the distance the clouds still have sunlight, as if it is sunset or sunrise in all directions, and the sky is only as dark as it is a few minutes after sunset, with only Venus and a few of the brighter stars easily visible up near the sun, and no stars visible on the horizons, which are brighter than the sky more directly above, and far brighter than the night-time darkness over the land.

We decided not to go near the place of longest duration. We had about two seconds less of toality, but saved nearly two hours of being stuck in traffic going and returning, and as we were nearly directly on the line of maximum eclipse, we actually had more totality than people who were a few kilometers north or south from the point of greatest totality duration (e.g., Carbondale), about 60 kilometers from where we were. This was our observation station, and you can see Arthur sitting here a few minutes before totality. |

View of the corona about two minutes into totality. With this Canon PowerShot image, you can see a little light on the moon around the rim, if you look at the large image. Photo by Eric Hadley-Ives (with Canon PowerShot SX720 HS. 1/250th second shutter speed; f/6.3; ISO 800).
|
About 20 seconds into totality I took this photo with my Canon EOS Rebel T2i and a good 400mm lens. With 1/200th of a second shutter speed the corona appears very large. Photo by Eric Hadley-Ives, Camera: Canon EOS Rebel T2i; Lens: Canon EF 100-400mm, f/5.6; 1/200th second; ISO 6400.
|
A longer shutter exposure (1/100th of a second) allows a different view of the corona. Photo by Eric Hadley-Ives, Camera: Canon EOS Rebel T2i; Lens: Canon EF 100-400mm, f/5.6; 1/100th second; ISO 6400.

First of three photographs of the moon and the sun’s corona. The changes in the corona take place over the scale of many seconds or a minute or two. Compare these images to ones taken in South Carolina, Wyoming, or Oregon to note how the corona changed over time.

Second of three photographs of the moon and the sun’s corona. It was taken about one second after the photo to the left. All these photos in this row were taken with a shutter speed of 1/4000th of a second, allowing more detail from the corona closest to the sun’s surface.

I notice that photos of the corona taken atop Casper Mountain, Wyoming several minutes before we took this photograph show similar patterns in the corona.

The moments after totality gave us another opportunity to play with shadows and projections of the sun’s crescent shape, observed here on some paper under the willow tree at the base of the levee. |
This shadow of my hand demonstrates that the pinhole light effect where light takes the form of the crescent sun requires very tiny holes for the light to squeeze through: the gap between the base of my fingers is small enough to produce the crescent, while further up my fingers the gap is too wide or long, and the crescent shape is malformed or absent.

The sun returns, and we must look at it and photograph it through a solar filter.

The Beisners, who let us look through their solar glasses; Tammy took some of the photographs on this page. |
There were several cars up on the levee near our car, and we met the Beisners during the eclipse. |

This little grasshopper is missing one of his jumping legs, and his wings are very small. It enjoyed perching on my iPhone.

The drive down to our observation post from our home in Springfield was about three hours. Here I am driving us back home.

As we drove on State Route 153 past Lively Grove, Illinois we saw a cumulonimbus cloud rising up in the north ahead of us and anticiapted the lightening and rain we would encouter a little later on our drive home.

One issue with driving on rural routes is the possibilty of getting stuck behind farm equipment. Photo by Eric Hadley-Ives.

Sometimes planters, cultivators, and other farm equipment are so wide that it is very difficult to pass by the tractor, especially with oncoming traffic as a threat. Photo by Eric Hadley-Ives.

The storm clouds were admirably dramatic as we drove home. Photo by Arthur Hadley-Ives.
