2015 Meeting Journal
 
December 6
LHAG Christmas Party at Kilaga Springs
Members enjoyed a luncheon buffet, a raffle and an astronomy quiz (with prizes).

how to locate them in the winter sky using Astronomy apps on cellphones, tablets and automated features of
members' telescopes.  Contact Bob Collins bobpcoll@community.net  (916-253-9890) for more information.
November 16 CIG DVD Lecture Series      "Cosmology - The History and Nature of our Universe" by Professor Mark Whittle
Lecture 29 - Back to GUT - Matter and Forces Merge
Lecture 30 - Puzzling Problems Remain
Lecture Discussion and Q & A
November 4 GM "Infrared Astronomy" by John Combes
Celestial objects such as gas and dust clouds, protostars and exoplanets are easily detected using the infrared part of
the spectrum. The Earth's atmosphere limits detecting infrared light which requires high altitude and space telescopes
to carry out the task. John described how astronomers view objects using the infrared portion of the spectrum.
October 22 TIG Ron Olson gave a presentation on locating planets, stars and deep sky objects that can be seen from Lincoln by
members using their own telescopes.  Contact Bob Collins bobpcoll@community.net  (916-253-9890) for more information.

September 2 GM "Saturn's F Ring: What We Know and How Do We Know It" by Robert French (SETI)
The most dynamic of Saturn's fascinating rings, the F Ring, was not seen until Pioneer 11 in 1979. Further observations by Voyager, Cassini and the Hubble Space Telescope have shown the F Ring to be astoundingly dynamic even on an hourly basis. Rob presented how we discovered these interesting facts and what we know about he ring structure, particle size, dynamics, chemical composition, environment, evolution over time, and the causes of rapid change. Many of these facts have just recently been published.
August 27 TIG The August meeting began with a Sky and Telescope video on "How to use a Telescope"
followed by members Al
Witten and Ron Yelton demonstrating how to align and use Alt/Az and equatorial telescopes. Contact Bob Collins bobpcoll@community.net (916-253-9890) for more information.

Lecture 24 - Understanding Element Abundances
Lecture Discussion and Q & A
August 5
Planetarium Show and Presentation      Professor David Dunn - "Eclipses in My Life"
Sierra College Professor David Dunn gave an excellent planetarium show and the presentation "Eclipses in My Life."
He described the various types of eclipses, when and where past eclipses occurred and when future eclipses will occur. A Total Lunar Eclipse will occur on Sept. 27 this year. This Lunar eclipse can be viewed at the LHAG Total
Eclipse of the Moon Viewing Party behind the Orchard Creek Lodge.
June 25 TIG The June meeting began with a Sky and Telescope video "How to Buy a Telescope.
This was followed by Al Witten
showed and described his two telescopes: a Dobsonian and a Schmidt-Maksutov. Contact Bob Collins bobpcoll@community.net  (916-253-9890) for more information.
June 11
Blue Canyon Star Party    
A large group of LHAG astronomers enjoyed clear, dark skies and warm weather at our Star Party at Blue Canyon
through a variety of telescopes with lens/mirror sizes ranging in sizes from 5.5 inches to 11 inches. Starbucks coffee
and cookies provided by Nina Mazzo were enjoyed by all. We saw Venus, Jupiter and three of its moons, Saturn and a
couple of its moons, double stars, galaxies, star clusters and nebulae objects.
June 3
Community Forum    "The Search for Extraterrestrial Civilizations" by Sierra College Professor Barry Rice
In his presentation, Professor Rice entertained the audience by having fun speculating about life in our galaxy. Why
isn’t it the case that we’ve detected aliens? (Or have we?) And you’ll learn why you should never again utter the
foolish phrase—“I think they’re out there, they just haven’t gotten here yet.” Prof. Rice discussed a comprehensive
list of factors including interstellar travel times, reported sightings, cover-up theories, conditions for life, and active
search.
May 28 TIG The initial meeting was very successful, and the group will have its second meeting on June 25.
This group will focus
on all aspects of owning and using personal telescopes. This will include purchasing a telescope for those who wish toown their own telescope, assistance on how to operate their personal telescope, and learning the basics of finding objects in the night sky to make the viewing experience more enjoyable.

program he initiated at the Cameron Park Rotary Community Observatory with the goal of teaching safe solar
astronomy to school children. The LHAG has scheduled a Solar Observing trip to the observatory on Thursday, May
21. RSVP to bob Collins, bobpcoll@community.net, 253-9890

March 4 GM "The Kepler Mission: 1000 Exoplanets and Counting" by Edna Devore
Edna Devore,
Director of Education and Outreach at the SETI Institute, took us on a tour of exoplanet discoveries made by NASA's Kepler Mission. Launched in 2009, the Kepler Mission space telescope has collected the light from almost 200,000 distant stars in search of their planets. As of 2015,more than 1,000 exoplanets have been confirmed out of more than 4,000 candidate planets. We learned about these discoveries, and what they tell us about our home galaxy.
What's New in Astronomy - Nina Mazzo presented an update on the Dawn Mission to the dwarf planet Ceres.

Lecture Discussion and Q & A
February 4 GM The Mars and Volatile Evolution (MAVEN)
The Mars and Volatile Evolution (MAVEN) was launched in Nov. 2013 and it had arrived and is orbiting Mars! It will
orbit the planet and study the top of its atmosphere and how it interacts with sunlight and with the Solar Wind. The
goal is to understand where the water and CO2 from an earlier atmosphere went. In this video, at a public lecture at
the American Geophysical Union Fall 2014 meeting, speakers discussed the mission concept, science observations
made during the cruise to get there and observations of comet Siding Spring (which made a close approach to Mars in
October 2014) as well as early observations of Mars' upper atmosphere. They also went into detail about how the
spacecraft was developed and launched and the day-to-day operations as it orbits Mars.

GM "Roswell Incident" by Don Wilson
Don presented the results of his investigation which revealed the truth behind the "Roswell Incident" in New Mexico's high desert.  The overall investigation encountered multiple erroneous interpretations of the observations which was further complicated by the relentless military cover-ups.
