Presented by RASC member Jay Lavender.

Technology continues to advance the capabilities of the amateur astronomer, and as a result so has it progressed the concomitant of solar observing. We will discuss some of the methods from simple to complex for safely observing the Sun as well as the amazing variety of passband filters currently available to the amateur solar astronomer. We will then wade into a little greater detail about the Sun itself and some of the solar phenomenon and features of interest to the solar observer. If we have clear skies following our discussion, please join me for some Hydrogen-alpha and Ca II K solar observing. Hope to see you there!

My Personal Five-Year Chase of NLC/Searching for NLC with Airport Cameras

My Personal Five-Year Chase of NLC/Searching for NLC with Airport Cameras

Presented by RASC members Mike Noble and Mark Zalcik.

Noctilucent clouds (NLC) are a sky-high phenomenon best-suited for observing right here in northern Alberta. The ideal dates to look for them are mid June to mid July, so come and celebrate the start of NLC peak season on June 22! The evening kicks off with a brief overview of NLC. Next, learn about Mike Noble’s earnest NLC-searching regimen, driving to many sites to catch NLC displays with his bevy of cameras. Then find out about searching for NLC on images generated at numerous airports across the country. If the weather looks good, stick around for evening twilight and we’ll collectively scan the sky for these mysterious clouds. The terrain just north of the community hall drops off into the Sturgeon River valley, yielding a nice flat horizon to view the NLC. See you there!

RASC Regular Meeting June 12, 2017 The IceCube Neutrino Observatory: Chasing Particles in Antarctica

7:30 PM Guest Speaker

Dr. Claudio Kopper
The IceCube Neutrino Observatory: Chasing Particles in Antarctica

The IceCube Neutrino Observatory is a particle detector built into a cubic kilometre of natural Antarctic glacier, located deep beneath the South Pole. It searches for interactions of a nearly massless subatomic particle called the neutrino. The IceCube observatory has a vast scientific program including searching for neutrinos from the most violent astrophysical sources such as exploding stars, gamma-ray bursts, and neutron stars as well as looking for signals from possible dark matter sources like the galactic centre. It is also a powerful tool to study the neutrino itself.
I will introduce neutrinos, describe the IceCube detector and highlight some of the recent results obtained from the data taken by the detector. I will also explain how IceCube could help solve the 100-year old mystery of the origin of “Cosmic Rays” – a flux of immensely high-energy particles, mainly originating from somewhere outside the Solar System.

How to Use A Telescope

Do you need help using your telescope? It’s a common complaint among first-time telescope owners: “I’ve got this new telescope and I can’t see a thing through it”. The aim of this Astro Café is to help you get the most out of your new telescope.

Bring your telescope to this Astro Café and experts from the RASC will help you learn how to use it. Let us show you how to make the most out of your telescope. Discover how to properly set up your telescope, how to find objects in the sky, what accessories would be useful to you and how to take care of your telescope.

This Astro Café starts later in the evening, so that if skies are clear, we can head outside and we will have the Moon and Jupiter as bright targets to view through your telescope.
