This eclipse conveniently cuts across the continental US and a partial eclipse will be visible from every state. You can use this interactive map http://xjubier.free.fr/en/site_pages/solar_eclipses/TSE_2017_GoogleMapFull.html to find out what people in your hometown will see. What will you see from campus? At 1:15 on the first day of classes, the partial eclipse will start. You probably won’t notice much at first because the photosphere is so bright, but by 2:40, about 75% of the sun will be covered by the moon. This is the maximum amount you will see in Lewisburg, and the partial eclipse will completely end by 4pm. Like I said in my last post, never look directly at the sun without eye protection (again, sun glasses don’t count). Blocking ¾ of the photosphere is not enough to prevent eye damage because the sun is so bright.
For the same reason, a 75% eclipse is too bright to see the faint corona around the sun, which is why we need to travel to the path of totality to take our scientific data. From Lewisburg, the eclipse will look like a crescent sun. If you really pay attention, you might notice that it’s a little darker than it typically is on a bright sunny day, as if there are high atmospheric clouds over the sun.
Wishing you could see totality too? Luckily, we plan to stream it live on YouTube! Tune in the day of to watch the whole eclipse through one of our telescopes! In the event that we don’t have enough bandwidth to stream video, we will be updating with still images as quickly as possible so everyone following along will see what we see.
