SIGMA Events Programme for 2017
Meetings are held on the first Friday* of every month at Birnie Village Hall near Elgin (unless otherwise stated). Doors open at 7pm for a 7.30pm start. Non-members are always welcome and refreshments are provided (for a small donation).
SIGMA regularly holds public observing sessions at its dark site outside Elgin. Visit our Upcoming Events page to see what we have planned.
* Please note that the January meeting is held at Lhanbryde Community Centre and the July meeting is held later in the month.
| Friday 6th January | SIGMA Stargazing Night Venue: Lhanbryde Community Centre SIGMA’s annual Stargazing meeting. Another chance to hold a joint club night and public observing session. Held at Lhanbryde, the event will give members and visitors a chance to see many of the wonders of the local night sky and talk with local Astronomers. |

| Friday 3rd February 2017 | Universe in a Nutshell Tim Browett, Robert Gordon’s College This talk will explore our expanding and evolving understanding of the Universe. Tim will examine the development of science’s views on the Universe’s turbulent 13.8 billion years of history, what we currently believe the state of the Universe to be, and finally examine possible outcomes in it’s future evolution. A number of practical and novel demonstrations will be used to translate the potentially mind-bending theories into tangible and manageable concepts. |

| Friday 3rd March 2017 | How do They Know That? Bill Leslie, SIGMA How can anyone know the size of a planet, its distance from the Sun and its mass? Bill will be explaining the science that astronomers use to answer these questions. |

| Friday 7th April 2017 | Recent Curiosities on Mars Pauline Macrae, Highlands Astronomical Society Pauline will be talking about Mars, and the discoveries made by the Curiosity Rover during its four and a half year trek across the red planet. |

The Best-Observed Solar Eclipse Ever? Dr. Hugh Hudson, University of Glasgow August 2017 will see a total solar eclipse crossing the entire breadth of the continental United States. From several points of view this will be a milestone: a long period of totality, excellent infrastructure, and remarkable new technology (smartphones, GPS, and the Cloud, for example). This eclipse will be more than pretty pictures because of this, and Dr. Hudson will describe some of the hoped-for advances in our understanding of the solar corona, the Sun itself, and the Moon too. It is hoped that citizen science can play a major role in discoveries following the event itself, via the massive archive that will result. Visit eclipsemega.movie for more information. Dr. Hudson will also describe the activities of the team at the partial solar eclipse in Patagonia (February 2017) in preparation for the big event. |

| Friday 21st July 2017 | 2nd Prof. George Fraser Memorial Lecture Venue: Morayvia, North Road, Kinloss In 2014 SIGMA, in association with Morayvia, held its first memorial lecture in honour of Prof. George Fraser (22 July 1955 - 18 March 2014). Born and brought up in Burghead, George was Professor of Detector Physics and Director of the Space Research Centre of the University of Leicester. Though his work was recognised internationally, his achievements are virtually unknown locally. Prof. Martin Hendry, University of Glasgow, a renowned international scientist and regular speaker at SIGMA will deliver this 2nd memorial lecture. 2020 Vision: Multi-Messenger Astronomy and Cosmology From Earth and Space-Based Observatories The direct detection of gravitational waves by LIGO, (Laser Interferometer Gravitational-Wave Observatory), from the collision of two massive black holes more than a billion light years from Earth, has been hailed as the scientific breakthrough of the century, opening up an entirely new way to explore our Universe, and future prospects for simultaneously observing both electro-magnetic and gravitational-wave signals in the distant cosmos. This new field of “multi-messenger" astronomy offers rich opportunities to address some of the deepest unsolved mysteries in astrophysics - from probing the runaway expansion of the Universe to understanding how stars and galaxies formed. This lecture will highlight some of the exciting discoveries that might lie ahead and showcase some of the remarkable technology that underpins our efforts to explore the Universe across the entire electromagnetic spectrum and beyond. |

| Friday 4th August 2017 | TV Astronomy Robert Law, Mills Observatory, Dundee Robert will show how to use simple video cameras to get pictures of the moon and planets with small telescopes. He will also show pictures from the 16 inch reflector telescope at Mills Observatory. |

|
| Friday 1st September 2017 | Hunting the Dragon Prof. Andy Lawrence, Royal Observatory Edinburgh Mysterious and violent events take place in the very centres of galaxies - huge outpourings of X-ray and ultraviolet radiation, jets streaking out at nearly the speed of light, and erratic changes from week to week. Andy will trace the history of how we have pieced together the puzzle over several decades, with telescopes, detectors, and theory, and look at what we think we understand now. |

| Friday 6th October 2017 | Transiting Extra-Solar Planets: From Hot Jupiters to Super-Earths Prof. Andrew Cameron, University of St Andrews Extrasolar planets that transit their host stars are highly prized, because we can measure their radii as well as their masses. Prof. Cameron will describe some of the problems faced in extracting planetary parameters from the various types of astronomical observation needed to deduce planetary bulk densities, which offer clues as to whether planets are mainly rocky, icy or gaseous. A bewildering variety of planetary compositions is beginning to emerge, many of which are not represented in our own solar system. In particular, analyses of the planet population found by the Kepler/K2 space mission suggest that we may soon have an idea of the prevalence of Earth-sized planets around other stars. |

| Friday 3rd November 2017 | Astrophotography and Nightscapes Maciej Winiarczyk - wildnorthskies.com Renowned astrophotographer Maciej will be explaining how he captures his stunning images of the Northern lights (Aurora) and wonderful nightscapes from his dark sky advantage point of Wick. |

| Friday 1st December 2017 | Christmas Quiz and Prize Draw for SIGMA Members and your Families Another chance to bring along the family for a night of fun, questions and mince pies to end the year. There will also be the usual Christmas raffle and an update on future planned events for SIGMA in 2017. |
