Pleasanton Middle School

Solar Eclipse - Monday, August 21st


Informacion in Espanol:

The Solar Eclipse: is TODAY!

Important Safety Information to Enjoy the Eclipse on Monday!   


Today, Monday August 21st, Pleasanton will begin to experience a partial solar eclipse at 9:01 am. In Pleasanton, approximately 80% of the sun will be covered by the moon for about 2 minutes and the entire eclipse will happen over 2 hours and 36 minutes.  This event presents many wonderful learning opportunities for our students.


It is very important to communicate the seriousness of eye safety with your children. Looking directly at the sun, even briefly, is extremely dangerous. It will not, at any point during the partial solar eclipse, be safe to look directly at the sun


School administrators and teachers in our district are aware of this safety information, and our science classes have activities planned around the eclipse on Monday. Some classes will be providing special solar eclipse glasses (regular sun glasses are not safe to view the eclipse), or other safe methods to experience the solar eclipse, such as a pinhole camera.  Every student has made pinhole viewers in their science classes and can use them to view the eclipse. Please remember to put them in your backpacks for Monday. Students that have science classes during 2nd & 3rd period will go out with their class to view – the students in science class will be provided the certified safe eclipse glasses (ISO 12312-2) to view. Other classes are invited to view the eclipse with staff supervision and their pinhole viewers or glasses. Our school will also be streaming the eclipse LIVE on our PMTV (Channel 16) for all to watch.


We recommend watching this short safety video from the Exploratorium with your students to help them understand the extreme danger of looking directly at the sun, and how to enjoy the solar eclipse safely.


The following two links describe how to make a pinhole camera, in case you want to make one (out of a cereal box or shoebox).
