Upcoming Events 2017

August 21, 2017, Solar Eclipse - More information to follow

July 21-23, 2017, Star-B-Q - More information to follow

May 19, 2017, Raj Dixit, Will Present on Hubble vs Your Scope at 8pm at Sacramento City College (SCC), in Mohr Hall Room 3. Meeting Directions
Raj will discuss the difference between the beautiful images you see on TV, in books and magazines, and on the internet, compared to what you actually see through a telescope!

April 21, 2017, Bill Goff, Will Present at 8pm at Sacramento City College (SCC), in Mohr Hall Room 3. Meeting Directions
will discuss some of the types of variables, why amateur observations are important, opportunities for pro/am collaboration and some exciting recent developments.

Bill began his venture in astronomy in the late 1950s with a small telescope observing Messier objects from his family's backyard. By the time he’d graduated from high school, he had completed grinding a mirror and made his first telescope. He has built several over the years.

In the 1980’s he met some observers from the AAVSO and liked visual variable star observing right away. It offered a structured way to plan observing that he found interesting. And besides, there were many types of variable stars to observe. He’s been a member ever since.

Later, as the technology improved he adopted CCD camera’s, and began a path of making precision measurements of variable star brightness changes.

February 17, 2017: Caitlin Everhart, Presentation on delta Scuti star components in eclipsing binary systems, 8pm at the Powerhouse Science Center - 3615 Auburn Blvd Sacramento, CA
Caitlin Everhart currently works in the museum education field, but once upon a time she was an astronomy intern at Juniata College in Huntingdon, PA. Her work involved searching for delta Scuti components in eclipsing binary systems, and the results of that research were ultimately presented at the 221st meeting of the American Astronomical Society.

Come hear Caitlin at the Power House Science Center for what is sure to be a Fascinating experience:

"When you look into the night sky, many of the “stars” you are seeing are actually multiple star systems: two, three, or even four stars orbiting around each other. Some estimates place 85% of the stars in the Milky Way in multiple star systems. A system with two stars is called a binary system. These systems can be very difficult to study from Earth since even our best telescopes usually cannot resolve these stars as being separate, but in one special case it becomes possible to study these systems. With two stars are orbiting each other such that their orbital plane lies in the line of sight of the observer, they eclipse each other. This results in a change in brightness for the system which is regular and observable. The size of that change can reveal information about the stars which might not have been possible to know without the special circumstance of an eclipsing binary system.

One piece of information is whether one of the component stars is a delta Scuti variable star. These stars are found by looking for small, regular changes in the light from that star and that change is extremely hard to find. In the special case of an eclipsing binary system, however, these stars are easier to identify!"

January 20, 2017: Jeff Baldwin, of the Stockton Astronomical Society (SAS), and Dr. Larry Grimes
Both are scheduled to fly on the NASA SOFIA mission this fall, and have agreed to share their experience with the SVAS members this January. More info will be coming soon. Check out their website at: SETI-Educators.
