The BOEC was declared Canada's 15th Dark Sky Preserve in Nov, 2012. At the ES Fox Observatory, we have a large reflecting telescope (a 28-inch Webster) and a 10-inch SCT on a GOTO mount that we use regularly in our public viewing sessions.
January/February 2017 astronomy events are now listed below and in COMING EVENTS
Observing at Fox Obs. for Jan and Feb is not scheduled but may occur on an impromptu basis, weather permitting. See BAS Calendar of Events below for contact info if you would like to join us. Public is welcome!
Next BAS club meeting is Mar 1, 2017 (7 pm) at Tom Thomson Art Gallery.
See Meeting Recap for a review of the Dec 7, 2016 meeting.

BAS CALENDAR OF EVENTS
Jan/Feb 2017 (the short list)
BAS regular meetings are the 1st Wed of the month at 7 pm at the Tom Thomson Art Gallery in Owen Sound (there are no regular meetings in January and February). Check the calendar here: [BAS 2017 Events Summary coming soon] for meeting dates and other events like public viewing nights at the Fox Observatory.
If you would like to be included in our list for impromptu observing nights contact Brett T. firstname.lastname@example.org or John H. email@example.com Some of the more interesting sky viewing opportunities are also described graphically in SKY SIGHTS.
NOTE: ALL observing events require clear skies. If it is overcast or raining, observing will NOT be possible. If you arrive at the venue and it is overcast or raining, there may not be any BAS members there. See COMING EVENTS for more details and instructions including a contact phone number if you are unsure about whether to attend due to weather. When visiting the Fox Observatory, please park at the main lot by the Learning Centre. Parking near the Fox is reserved for disability access and equipment drop-off.
NOTE: BAS Meetings and public viewings are open to the public at no charge. BAS viewing at ES Fox Observatory is also generally open to the public (dates in monthly listing below and in our BAS 2017 Events Summary coming soon). We welcome out-of-town guests on all of our listed observing nights. Individuals or groups may request private tours on other dates (subject to availability of guides) by contacting John H. at: firstname.lastname@example.org . We also offer private tours/observing on a fee basis.
Our next BAS Wed meeting at the Tom Thomson Art Gallery is Mar 1, 2017 at 7pm. This will be our first meeting of 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 remaining 2016 events and Jan/Feb 2017 events listed below can be found on the COMING EVENTS page. A list of ASTRONOMY EVENTS FOR 2017 is available here: ASTRONOMY EVENTS 2017. Note this list changes from time to time as additional astronomy events are added.

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. Look for Venus (and Mars, too) crossing Capricornus in December, then through Aquarius and into Pisces in January 2017. Both will be near the “Circlet” or "Western Fish" by the third week of January. All winter long Venus will be playing catch-up with Mars and eventually the faster Venus gets closer but then it stops its own eastward motion and starts retrograding to the west. Date of closest approach is Feb 2 or so when the pair are about 5.5° apart. This is not that close as planetary appulses go and not the closest that these two get this year. On Oct 5, 2017 in the morning sky, they are a mere 0.2° (15 minutes) apart when they rise in the east around 5:30 am DST. Now, that’s better!
The image below was taken Jan 1, 2017 (my first astro-image of 2017!) and shows Mars (magnitude 0.9) at upper left, Venus is pretty obvious at magnitude -4.3 and the 3.5 day old crescent Moon is at lower right. It was a bit hazy that night and glows are seen around the brightest objects. The nice diffraction spikes are produced by stopping the lens down, in this case it was at f/5.6.
Image by John H. Canon 6D at 100 mm at f/5.6 ISO 3200, 16 s exp. on tripod
Venus watching will get even better as the winter wears on, and there are 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 5° close approach of Venus to Mars. After this, the normal westward motion of the sky will carry both planets lower and by spring of 2017 they 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
A comet for Christmas and New Years: Comet 45P/
Finally a comet visible in binoculars has returned to our sky! Comet 45P/ will be visible for the rest of 2016 and into February 2017. Read all about it here: Comet 45P A finder chart is available on our VIS.COMETS page.

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).
