FLEETVILLE — The grounds of Keystone College’s Thomas G. Cupillari Observatory were packed Monday afternoon, as people flooded in to catch a glimpse of the sun through the observatory’s telescopes. As the moon began to pass in front of the sun, some people watched through special solar eclipse glasses, while others peered through various filtered instruments. A projector was also set up indoors, showing a live stream of the eclipse on a large screen.

According to Keystone College spokesperson Fran Calpin, an estimate of close to 1,000 people were in attendance.

This was the first time since 1918 a total eclipse crossed the entire country from coast to coast. A solar eclipse occurs when the moon passes in front of the sun, casting a shadow on the surface of the earth. Locally, the sun was only about 70 percent covered, creating the need for filters for safe observation.
