To view a solar eclipse, it is essential that you have appropriate protective eyewear! Sunglasses are not sufficient for this purpose. You will need glasses with special filters designed for viewing the sun. MCPL was lucky enough to apply for and receive a supply of eclipse glasses from Starnet Libraries through a grant funded by the Moore Foundation. Several MCPL branches are hosting eclipse-related programs. Some of those branches will offer a limited supply of eclipse glasses for programs.
Friends of the Library bookstores are selling eclipse glasses at both of their locations in Rockville and Silver Spring. The glasses have been in hot demand, so please contact the Friends directly to check on current supply. There are also several reputable companies manufacturing eclipse glasses recommended by NASA - American Paper Optics, Baader Planetarium (AstroSolar Silver/Gold film only), Rainbow Symphony, Thousand Oaks Optical, and TSE 17. The most important thing to look for in your eclipse glasses is that they meet the ISO 12312-2 international standard. For more information on safely viewing the eclipse, head over to NASA’s Eclipse Safety website.
Tips for enjoying the eclipse:
• In Montgomery County, the eclipse will peak at approximately 2:42pm.
• Always wear protective eyewear! Make sure your eyewear is not damaged or scratched and that the lenses are completely secured to the glasses. Check that they meet the ISO 12312-2 requirement.
• Do NOT view the eclipse through a camera, telescope or binoculars even if you’re wearing your eclipse glasses. A specialized filter is needed for optical devices.
• Be prepared for the long haul! The eclipse can last about 2.5 hours from start to finish. If you plan to be outside, bring sunscreen and water.
• Check the weather forecast. If we luck out and it’s cloudy during the time of the eclipse, you can live stream the event on the internet. Some libraries may also do this if views are obstructed.
