The final Membership Meeting of the Cuyahoga Astronomical Association (CAA) for 2019 will take place Monday, November 11. The meeting will feature a presentation by member Steve Gallant entitled, “Catching the Sun: Robert McMath and the McMath-Hulbert Solar Observatory.”

Located north of Pontiac, Michigan and opened in 1929, after the initial attempts to study the moon, the main preoccupation of the observatory was the sun. McMath-Hulbert was once the second largest solar observatory in the world. Spears will fill us in on the observatory’s history and the current efforts to preserve and promote its continued use!

The CAA’s monthly meetings are held on the second Monday of every month except December at 7:30 p.m. in the Rocky River Nature Center; 24000 Valley Parkway; North Olmsted, Ohio, in the Cleveland Metroparks. Meeting programs are open to the public. Following the presentation and a brief social break, the club will conduct its membership business meeting.

October 21 Membership Meeting: “Apollo 11: Fifty Years Later” (rescheduled)

Jay Reynolds

Our monthly meeting originally scheduled for October 14 at the Rocky River Nature Center was canceled. The nature center parking lot was being resurfaced. The meeting was rescheduled for 7:30 p.m., October 21.

The October 2019 meeting of the Cuyahoga Astronomical Association (CAA) will feature a presentation by club member and Cleveland State University Research Astronomer Jay Reynolds. The historic 1969 Apollo 11 moon landing will be the focus of the talk which will progress into NASA’s next steps in crewed space exploration following the end of the shuttle program.

The CAA’s monthly meetings are held on the second Monday of every month except December at 7:30 p.m. in the Rocky River Nature Center; 24000 Valley Parkway; North Olmsted, Ohio, in the Cleveland Metroparks. Meeting programs are open to the public. Following the presentation and a brief social break, the club will conduct its membership business meeting.

September 9: Membership Meeting / Dark Matter and Gravity

The September 2019 meeting of the Cuyahoga Astronomical Association (CAA) will feature a presentation by Dr. Stacy McGaugh, Case Western University Professor and Chair of Astronomy. In “Dark Matter and Gravity in the Universe,” Dr. McGaugh will discuss his work on the search for dark matter and the possibility that it does not exist and we simply do not understand gravity! He has co-authored several papers outlining this controversial view.

August 12 Membership Meeting features talk on the European Scientific Revolution

Anne Kugler, Ph.D.

The August 12, 2019 meeting of the Cuyahoga Astronomical Association (CAA) will host featured speaker Anne Kugler, Professor of History, Associate Dean of Graduate Studies, and Director of the M.A. in Humanities, John Carroll University. Dr. Kugler’s talk titled, “Madame du Chatelet and the Origins of Science,” will describe how the Scientific Revolution challenged everything Europeans understood about humans and the natural world. The Enlightenment shaped how this new field of “science” was practiced in the social environment. The example of Madame du Chatelet shows how the development of physics and astronomy were grounded in the cultural context of eighteenth-century France.

The CAA’s monthly meetings are held on the second Monday of every month (except December) at 7:30 PM at the Rocky River Nature Center; 24000 Valley Parkway; North Olmsted, Ohio, in the Cleveland Metroparks. Meeting programs are open to the public. Following the presentation and a brief social break, the club will conduct its membership business meeting.

July Membership Meeting: LIGO Part 2

Madeline Wade, Ph.D.

The July 2019 membership meeting of the Cuyahoga Astronomical Association (CAA) will take place Monday, July 8, beginning at 7:30 PM.

Featured speaker for the evening will be Dr. Madeline Wade, Assistant Professor of Physics, Kenyon College. Dr. Wade writes: “The Advanced Laser Interferometer Gravitational-wave Observatory (aLIGO) has been making ground-breaking discoveries since the moment it turned on in 2015. The LIGO and Virgo Scientific Collaborations have published results for 11 total gravitational wave detections. We have detected gravitational waves from ten merging black hole systems and one merging neutron star system. In this talk, I will give an overview of gravitational-wave physics, the LIGO detectors, and give some highlights of the current discoveries. I will also discuss some of the current and ongoing research I am involved in, including calibration of the LIGO instruments and applications of machine learning algorithms to improve the quality of LIGO data.”

The CAA’s monthly meetings are held on the second Monday of every month (except December) at 7:30 PM at the Rocky River Nature Center; 24000 Valley Parkway; North Olmsted, Ohio, in the Cleveland Metroparks. Meeting programs are open to the public. Following the presentation and a brief social break, the club will conduct its membership business meeting.

The March 2019 Membership Meeting of the Cuyahoga Astronomical Association will take place on Monday, March 11 beginning at 7:30 PM. The evening’s program, “Gravitational Waves from Colliding Black Holes,” will be presented by Rob Owen, Associate Professor of Physics and Astronomy, at Oberlin College.

Dr. Owen is a member of the Simulating Extreme Spacetimes collaboration (www.black-holes.org), which carries out supercomputer simulations of colliding black holes and neutron stars. Such simulations are essential for relating gravitational wave signals (such as those measured by the revolutionary LIGO observatory) to the astrophysical sources that produce them. In this talk he will describe the work and the often misunderstood physics of black holes and how they relate to the structure of space and time!

The CAA’s monthly meetings are held on the second Monday of every month (except December) at 7:30 PM at the Rocky River Nature Center; 24000 Valley Parkway; North Olmsted, Ohio, in the Cleveland Metroparks. Meeting programs are open to the public. Following the presentation and a brief social break, the club will conduct its membership business meeting.

The Monday, February 11 meeting of the Cuyahoga Astronomical Association, will feature John Ruhl, Ph.D., Professor of Physics and Cosmology at Case Western Reserve University, as guest speaker. In his talk, “Looking for the Dark,” Dr.Ruhl will describe the latest findings from two new and unique projects designed to utilize gravity waves and the Cosmic Microwave Background (CMB) radiation to search for the mysterious Dark Energy that is causing our universe to expand!

Following the presentation and a brief social break, the club will conduct its membership business meeting.
