Generally, about 60 degrees over the horizon in the south-southeastern sky.

What’s special about Lewellen, Nebraska, and eclipses?
According NASA, it is one of two areas that have not seen a total solar eclipse in more than 1,000 years. The other is Fort Morgan in eastern Colorado.
Is it safe to watch the eclipse?
Viewers must exercise extreme caution to avoid damaging their eyes. During the partial phases, viewers must wear special eclipse glasses. Even the darkest sunglasses won’t do. Lenses of eclipse glasses are extremely dense, blocking harmful rays. According to NASA, four manufacturers have certified that their eclipse glasses and hand-held solar viewers meet the ISO 12312-2 international standard for such products: Rainbow Symphony, American Paper Optics, Thousand Oaks Optical, and TSE 17.
NASA recommends that even people wearing eclipse glasses should look away frequently to cool and rest their eyes.
During the brief period of totality, when the sun is completely covered, the eclipse can be viewed with the naked eye. But viewers should look away and put on their glasses as soon as the sun emerges again.
Since Omaha won’t see the total eclipse, Omahans will need glasses for the entire event, unless they use a pinhole camera. By making a hole with your fingers or in a sturdy card, you can project the eclipse onto the sidewalk or a piece of paper.
