Come see the Night Sky at Knightsen Elementary!

Tuesday, March 7 @ 6:00-8:00 PM on the blacktop

We have a wonderful opportunity to have the Mt. Diablo Astronomical Society, MDAS, come to our school. The volunteers will share their time and telescopes to bring the Universe to our students. We will begin with a short introduction at 6:00 on the blacktop and then spend the rest of the time looking for different objects in the night sky.

Rain or Shine!‚Äč We will have alternate indoor Astronomy activities if the weather does not cooperate.

Please join us for an evening of fun and exploration! Students must be with an adult at all times. We need to let MDAS know how many people will be here, so they can have enough telescopes set-up for us. Please return the notice to attend by Friday March 3!
