Our next BAS Wed meeting at the Tom Thomson Art Gallery is Dec 7, 2016 at 7pm. This is our year-end Christmas social so members are asked to please bring goodies to share. [The Christmas meeting is more informal, the only official presentation is a re-cap from the president and a look ahead to 2017]. Meetings usually consist of a short business meeting and include a speaker or presentation on an astronomy topic. More details can be found in COMING EVENTS.
More details for the events listed below can be found on the COMING EVENTS page. A list of astronomy events for 2016 is available here: Astro Events 2016. Note this list changes from time to time as additional astronomy events are added.
A list of BAS events (meeting dates, public observing sessions, etc.) for 2016 is separately available here: BAS 2016 Events Summary. This list may also change as events are confirmed, etc.

Naked Eye/Binocular Astronomy Events :
Venus is back as Evening Star -you can't miss it!
Venus now is the prominent Evening Star above the SW horizon after sunset. The image below was taken Nov 18, 2016 and includes Mars at upper left just inside the border of Capricornus. In this image, Venus has just passed Kaus Borealis and is just to the left of the top star of the Teapot with two of the handle stars visible through the hazy clouds. Venus watching will only get better as the winter wears on, and there two planetary appulses to watch for. On January 12, when Venus is only 50% illuminated, it will pass Neptune with only a half degree to spare but seeing both Neptune and the phase of Venus requires a telescope. A month later, on February 2, 2017, there is a close approach of Venus to Mars, -about 5 degrees of separation. After the close approach to Mars, both planets sink into the western sky and by spring of 2017 both Mars and Venus will be lost below the western horizon. The crescent Moon is near Venus and Mars on the first few days of each month Dec, Jan and Feb, making a nice grouping for photographers.
A thorough explanation of the current Venus appearance can be found on Brian Ventrudo's Cosmic Pursuits website here: Venus viewing Guide 2016-2017

Supermoon viewing was pretty super:
Image by John H. (St. Mary's Church)
Image above is a composite image taken Nov 14, 2016. Canon 60Da, 1.8 s, ISO 2000, 260 mm focal length. The FM image was 1/500 s at 170 mm. These images were taken looking across the Owen Sound harbour about 7 pm. The Full Moon reached its perigee about 9 am Nov 14 so this image is 10 hours "off". Other BAS imagers got a closer FM to perigee -only 2 hours off -image below.
Image below is Julian D's single image looking west over the harbour and misses the exact point of perigee by only 2 hours or so. Image was with a 200 mm lens on a Sony camera at 1/6 s, ISO 100. You can tell that this was taken at moonset (western sky)because the "Lady on the Moon" is looking up, not leftwards.

Thin Moon Challenge: Can you beat 21 h?
Image above is a 24-hour young crescent and was taken Mar 16, 2010. Canon 20Da, 0.5 seconds, ISO 400, 400 mm focal length. A 21-hour crescent is not much thinner than this if you are looking to spot one. There is a detailed listing of thin crescents, both before and after NM in the BAS Weblog which you should see if you are interested in breaking the 21-hour record held by Lorraine R. and Aaron T.

From Our Astrophotographers:
Frank Williams latest submission to the "BAS Hall of Astrophotographic Fame" is an image of M17, or the Swan Nebula in Sagittarius.
"worked on Swan Nebula M17 during Starfest week from my little observatory in Allenford, and with cloudy weather here got to processing it. This has Luminance 1 hour, red filter 90 minutes, blue and green filters 75 min [using a] 140 mm TEC apochromatic [refractor] sbig STL 11000 camera cooled to -20c (As cold as I could get it running peltier cooler flat out). Processed in Pixinsight slight crop (to remove misaligned frames)". All I can add is "WOW!"
The countdown to the Great Aug 21 2017 Solar Eclipse continues:

Auroral displays in our area are declining as we have passed solar maximum. There have been periods of "blank Sun" where sunspots have been totally absent for a time. However, at far northern and southern latitudes near the auroral ovals, sometimes magnetic disturbances from the sun produce auroras even without visible sunspots. So if the auroral oval in the graphic below is showing an intense RED, aurora borealis may be visible from your location. The graphic is updated regularly with time indicated at the top in UT so subtract 5 h to get local EST, or 4 h for DST. (Use the appropriate factor for other time zones).

A recent meeting of BAS showed images from the CFHT on Mauna Kea. By popular demand, this space will be devoted to showcasing some of these. Have a look at this site for more: CFHT Image Of Month
