The October 2014
from Colleen O'Hare...
Penticton meeting Thurs. October 2
Talk about first hand astronomical discoveries! A previously unknown interaction between old planetary nebulae and the interstellar medium which was recently discovered by Ryan Ransom and his radio astronomy team, and described by him at the September meeting in Penticton, prompted a question about how scientists select a subject for study? This question will be addressed at the October meeting by retired radio astronomer Chris Purton who with Sun Kwok were the discoverers of the 'Slow and Fast Winds which account for the appearance of Planetary Nebulae'. Chris will explain how they came up with the idea in the 1970's and how they proved their theory. The meeting will be held at 7.15pm in the regular C O2 meeting room in the Sunoka building of the Penticton campus of Okanagan College.
Kelowna meeting Tues. October 7
'Gravity', it's not just a good idea, it's a law. In the presentation at the Oct. 7 Kelowna meeting, Colleen O'Hare will be taking a look at gravity. After the PowerPoint we will be encouraged to get hands-on with a gravity well brought in for the occasion. Sound intriguing? Then be sure to attend and see for yourself what it's all about. Colleen will use both the main presentation as well as the Constellation of the Month time to cover different her subject.
The meeting will be held at 7:30pm in the Lab Building at the Okanagan College Kelowna Campus in Room C368.
Vernon meeting Wed. October 29
The main program for the October 29 meeting in Vernon will be 'The Mariner 10 Mercury Mission' by Jerry Thompson who played a part on the mission team. Also on the program will be the 'Mystery Constellation and Observing Challenge' which will be led by John Karlsson and Jim Kanester. The topic for the pre-meeting Beginners Telescope Session which starts at 6.30pm is to be announced. The regular meeting will start at 7.15pm, also in the basement of the main building of the Okanagan Science Centre on the east side of Polson Park just off Highway 6. The entrance to the nicely appointed room is from the rear of the building.
Picture of the Month
This month it was Mark Force who was riding solo for his Picture of the Month Selection Committee colleague Frank Stariha. Mark commented that a worthy candidate was selected "after reviewing the wonderful selection of pictures, reading my tea leaves and consulting the Oracle of Peachland" The October Picture of the Month is a view of NGC 7023 - The Iris Nebula, which was sketched by John Karlsson on August 3, 2014 at the Mount Kobau Star Party. Mark commented that the sketch of NGC 7023 pulled ahead in the final stretch, noting, "This is not the easiest object to see, let alone capture the delicate nature of the Iris itself. I still remember looking at this object at Mt. Kobau several years ago and noting that it is most obvious due to the lack of anything around a fuzzy star. It was only after studying it (plus some extra oxygen) that the subtle nature revealed itself." Other candidate pictures included pictures of the Moon by Vlado Neykov, pictures of the green and blue flash taken in Hawaii by Hugh Pett, a new picture of M31 by David Player, and pictures of moonrise taken in Cuba following Hurricane Karen in 2013 by Patricia Reid.
These as well as other pictures by Jim Failes (Aug.) and Dave Gamble (Sept.) which were ineligible due to our two month waiting period can be seen at http://rascoc.zenfolio.com/f166015629.
Editor Hugh Pett welcomes submissions of astronomy observations, experiences and other ideas and topics. Deadline for material is the 8th of the month, to be published on the 15th; September to June.

The club website is updated by Andrew Bennett and Dave Gamble with a view to providing everything you ever wanted to know about Okanagan Centre RASC. As well as Outreach and many other club activity pages, the What's Up page provides heads up notes of what is in the sky on particular nights. The About Us page links to the club Library and other services. The website is also a portal to many links including our Zenfolio Image Gallery.
Remember to check out Dave Gamble’s ‘What’s Up’ page for a whole month full of observing musts as well at pictures contributes to by Jim Failes.
As well, Dave will be regularly sending What’s Up information to everyone on the AstroOkanagan email discussion group. Another great reason to join in!
The Google Discussion Group is a real-time link between members of our OC RASC meeting groups. A message might give you a heads-up on a new celestial
phenomenon, an alert about an Outreach event you could take part in or other timely news. You can start to receive the messages by contacting Guy Mackie at firstname.lastname@example.org or Mikkel Steine at email@example.com.
