President's Message April 2012

By Tom Thibault

First, let me thank all of you for your support over the last two years as your President. It has been your support that has made my term so enjoyable and rewarding. It seems like only yesterday I became a member of this wonderful organization. While my active interest in astronomy has been rather short when compared to that of other long-time members, I have found the willingness of our members to advise their fellow astronomers invaluable to my continued interest and advancement in astronomy.

Prior to joining the organization, my interest was a somewhat solitary pursuit. My days were spent soaking in all the information relating to astronomy I could learn from magazines, books, and the web. When evening arrived I found myself, for the most part, alone behind the eyepiece. I found this time as my sanctuary, and the stressful activities of the day would melt away.

Over time I found I wanted to share my love of astronomy with others as well. Astronomy is a broad subject with many branches of interest. What better way to expose yourself to these than to meet and discuss with those with similar interests who are actively involved.

This was the reason I joined Skyscrapers. After researching the organizations in the area, Skyscrapers seemed to be the best fit for me. As luck had it, Chris, an acquaintance of my wife Lisa and I, told us that her husband Bing was a Skyscrapers member. Bing invited me as his guest to a Skyscrapers Monthly Meeting. I joined Skyscrapers following that meeting and have been a member ever since. What I have found is a wonderful group of individuals with a deep love of astronomy. The long and deep history of the society is matched by the sum of its membership. Skyscrapers are individuals that range from the casual observer to those that have a wealth of knowledge in specific and or varied aspects of astronomy.

My advice to all current members and those considering membership is to make the most of what Skyscrapers has to offer. I personally have a somewhat outgoing personality and find it easy to approach people. Those that do not, I would urge to make that effort. I have found our members to be very friendly and happy to share their experience with anyone whom inquire of it.

I began as a strictly visual observer, and over the years, have expanded to Astrophotography. I have found the advice and knowledge of a number of our members invaluable in improving in this endeavor. Our membership is diverse with members of all aspects of astronomy and willing to share with others. We all have an interest in continuing the success of our organization. It takes all of us to accomplish this, so participation by our membership will insure the continuing success of Skyscrapers.

Professor Tim Barker returned in March as our featured speaker. Professor Barker’s presentation of the Apollo Missions was well received. Professor Barker’s previous presentation was a hands-on event, and we were provided with another at our March Meeting. Professor Barker set up a microscope for everyone to view NASA’s thin-sliced lunar samples. He also displayed a number of full samples from other heavenly bodies from our solar system. Thank you, Professor Barker for another great presentation.      

Our business meeting followed. Nomination Committee Chairperson Dave Huestis announced the committee’s nominations and also accepted nominations from the floor. Dave was followed by the presentation of the proposed revisions to our Constitution and Bylaws, Membership Dues structure, and our 2012-2013 Operating Budget. All received motions for discussion and vote at our April Meeting. Copies of the March presentation and supporting documents are available on our web site and hard copies will be available at the April Meeting to aid in your decision.

I am looking forward to seeing all of you at our April 13 Meeting. We have a full agenda: our featured speaker will be Professor Brandon Murakami of Rhode Island College. Professor Murakami will provide us all with some insights into the world of particle physics and the work surrounding this field of science.

Our business meeting will follow and will include discussions and vote in regards to our Membership Due structure, 2012/2013 Operating Budget, and Constitution and Bylaws. The results of our Annual Elections will also be announced resulting in the installation of our society’s newly elected administration.

While this will be my last Monthly Meeting as President, I look forward to continuing as an active member of this great organization.

Rare muon decay in the Large Hadron Collider era

Brandon Murakami

The muon is a particle differs from electrons only by virtue of having roughly 200 times the electron's mass and being unstable, but is otherwise identical. 100% of experimentally observed muon decays result in an electron and two neutrinos, another exotic particle. Meanwhile, the primary mission of the Large Hadron Collider is to observe and measure the properties of the Higgs boson, a particle responsible for generating all known particle masses and bestowing light with its fundamental properties. A compelling technical problem with the Higgs boson requires solutions with hypothetical particles that lead to predictions of rare muon decays. Specifically, muons are generically predicted to decay to an electron and photon -- a phenomena marked by the absence of the usual accompanying neutrino

Algieba: Double Star in Leo

Algieba: Double Star in Leo

: By Glenn Chaple
One of the finest double stars in the spring sky – indeed, in all the heavens – is gamma (y) Leonis. Its proper name, Algieba, comes from the Arabic Al Jabbah (The Lion’s Mane).

April Meteor Shower

: By Dave Huestis
I haven't written about the April Lyrids for a few years now because the shower had been in decline, and the observing conditions were always poor to fair at best. Well, this year the shower peaks at around midnight on the night of April 21-22, and, best of all, the Moon will be New and will not blot out any of the meteors.

Astronomical Events Determine Easter Observance

: By Dave Huestis
The motion of the heavens is a precise clock and calendar that can be used to determine when to celebrate special events. One doesn’t have to observe the sky for too long a period of time to notice the cyclic phases of the Moon, or the changing position of the Sun relative to the horizon over the course of a year.

Solar Activity Primer

: By Dave Huestis
With the increase in very energetic solar flares, I thought it was prudent to provide a basic primer on our Sun and the reasons for its recent outbursts.

Northern Lights Primer

: By Dave Huestis
As the Sun’s activity continues to climb to solar maximum in 2013, you can expect the frequency and intensity of geomagnetic storms to increase as well, and with it the chance to witness a beautiful display of the northern lights from right here in southern New England.
