San Francisco Amateur Astronomers (SFAA) are hosting two events in the coming days, both open to the public at no charge.
The monthly meeting of the SFAA takes place on Wednesday evening August 19th at 7:30 pm at the Randall Museum in San Francisco. From the SFAA: "Jack Welch of the Robert Ferguson Observatory in Sonoma gives a presentation on how we measure time and how time measurement is handled in various astronomy and space situations. Welch will explain how our understanding of time measurement has changed as technology and theory have developed, and will explore some of the special challenges satellites and spacecraft have when it comes to timekeeping."
The monthly SFAA event on Mount Tamalpais in Marin features a speaker and a public Star Party. It takes place at the Mountain Theater on Mt. Tam on Saturday August 22nd at 8:30 pm (lecture) with the star party immediately following the lecture. From the SFAA: "Dr. Anthony Coloprete of NASA-Ames will fill us in on all the details of the LCROSS mission. Two spacecrafts are on their way to the moon, and the impending impact on October 9 will be visible even with small scopes from Earth. Why crash into the moon? Dr. Coloprete’s talk 'Prospecting for Water on the Moon' reveals all."
The SFAA welcomes all to their events each month. I hope to see you at one of these events.
