Events:

Friday December 13th isn't a day of bad luck, it's the best day to see the Geminid Meteor Shower during the Friday Night Free Public Observing at Observatory Park, Turner Farm.  Observing will extend to 11pm at the park.  Bring a chair or blanket or ground covering to watch the sky for meteors.  Best seen with the unaided eye...no binoculars or telescopes required.  Note:  the moon will be close to full, so its light will wash out the fainter meteors.  Come into the observatory and get a close up view of the moon through one of the Roll-Top observatory's telescopes. Remember to dress for cold weather.
