A limited supply of Solar Eclipse glasses will be available through the MCLS and OWWL Member Libraries. Please contact your Local MCLS or OWWL Member Library to ask about how and when you can get glasses through the library. Please be respectful of how each library has chosen to distribute glasses to meet the needs of as many community members as possible and consider that family members/friends can share glasses.

The only safe way to look directly at the partial eclipse phases of the Sun (even at 99.9% coverage) is through eclipse glasses. Alternate projection methods can be used to view the partial phases of the eclipse.

I have a strip of film which I was trying to project onto a wall using a torch. I noticed the image was out of focus, but I don't understand why.
