Note: Observing is weather dependant -see Weather Information note at right.

BAS Meeting Locations: (not weather dependant)
Meetings happen at 7 pm at
ES Fox Observatory (ONLY on July 6 and Sep 7 in 2016) (washrooms are available) (map)
Tom Thomson Art Gallery Meeting Room Lower Level STARTING MAY 4, 2016

Observing Locations: (all locations are handicap accessible)

Our events happen mostly at the ES Fox Observatory (click for map) but there are other venues periodically. See the COMING EVENTS list for details.

observing locations are “remote locations” meaning there are NO permanent on-site washroom facilities. A portable washroom is located near the Fox Observatory for the summer only.

BAS Observing Events (dates listed below) will occur at the ES Fox Observatory (3092 Bruce Rd 13) at the Bluewater Outdoor Ed Centre. Viewing at the observatory is WEATHER DEPENDENT. See notes below for more about weather.

Best observing occurs during NM and LQ. When the Moon brightens the sky at FQ and FM fainter objects are not as easily seen. The Moon, planets, and star clusters are usually visible even during FM nights using our GOTO telescope.

Note: Some events are for BAS members and guests only, others are “public welcome” events and usually are admission by donation. School-aged children are always free and welcome to attend with parents or guardians. Refer to each listing in COMING EVENTS for details. If you are coming from a distance we will try to accommodate you. Contact us by phone (519-371-0670) ahead of time.


ALL observing events require clear skies. If it is overcast or raining, the observing event will NOT be possible. If you arrive at the venue, there may not be any BAS members there. Only BAS monthly meetings occur rain or shine.

If skies are partly cloudy, check the ES Fox Observatory
Clear Sky Clock for weather prospects or call 519-371-0670 to confirm the event.

This list was updated Aug 2 with events to the end of September 2016 .

Note: BAS meetings are NOT held in January and February but impromptu observing sessions continue on weekends at the Fox Observatory. Contact Brett T. at or John H. at to be put on the alert list for these.

Stargazing at the Fox Observatory is only possible weather permitting. When visiting the observatory, park in the lot near the Learning Centre and walk to the observatory please. Washrooms at the Learning Centre will be available for all ES Fox events and a portable washroom is on site for the summer.

Astronomical and BAS viewing events July to Sep 2016:

BAS meetings will be held at the Tom Thomson Art Gallery (May 4, June 1, Oct 5, Nov 2, Dec 7) or at Fox Observatory (July 6 and Sep 7 only).

July 2016

Jul 1 to 3 (Fri to Sun) Bruce Pen National Park Dark Sky Weekend Our annual Dark Sky Weekend at the Bruce Peninsula National Park. BAS has a group campsite where we get to relax during the day (or attend star talks) and star gaze at night, weather permitting. We generally set up in the parking lot at the Head of Trails for public viewing and laser-guided star shows. Members must register with Brett T. or John H to reserve a campsite. Camping starts Thu night Jun 30 until Sunday afternoon July 3.

Jul 4 Mon NM

Jul 6 Wed Regular Meeting 7 pm at ES Fox Observatory This is a movie night (or Speaker TBA) and may involve shorter astronomy movie segments(original videos or from the internet) or perhaps a longer presentation from the Perimeter Institute, for ex. You never know what you will get. Public Welcome

Jul 8 Fri Grey Roots Public viewing in the main parking lot starts at twilight around 9 pm or so. Above the western horizon, there is a crescent Moon to view right beside Jupiter AND Saturn and Mars in the southern sky. BAS members usually have a variety of scopes for viewing. Public Welcome

Jul 9 Sat Fox Dark of Moon Viewing night (BAS members and guests). If weather prevents observing, our backup night is Sunday (or even Friday night if weather looks poor for Saturday). Contact Brett T. or John H if you wish to be put on the alert list. Please park near the Learning Centre and follow the lane way between the barn and Centre to the ES Fox building. No vehicles are allowed at the observatory while we are hosting star parties. Bring a red flashlight if you have one.

Jul   11 Mon FQ

Jul   16 Sat Venus and Mercury close approach in twilight in western sky. The pair all be visible all day separated by about a half degree east of the Sun. By sunset at 9:04 pm, Venus/Mercury are about 6° high and drop to less than 2° about 30 minutes later. A flat western horizon will be required.

Jul    19 Tue FM

Jul 22/23/24 Fri/Sat/Sun Whispering Pines Stargazing Weekend is becoming our "go-to" event for the year. Camping facilities are excellent and BAS members camp for free. More information will be available soon. One of the nights (Friday or Saturday weather permitting) is a public viewing night for campers. BAS members should contact Greg Rodgers at asap to reserve a place.

Jul  26 Tue LQ

Jul  27 Wed  15:32 Delta Aquariid Meteor Shower: ZHR = 20. This is a rather sparse shower and peaks in the daytime.

August 2016

Aug  2 Mon: NM

Aug  3 Wed:  Starfest starts tomorrow and BAS exec will be busy getting ready so our regular meeting is cancelled.

Aug  4 - 7 Thu - Sun: STARFEST, the biggest and best amateur astronomy gathering happens this weekend and you can get a head start on the best camp spots by arriving Thu. Aug 4. BAS usually camps out at the top of the hill just past the checkpoint and just before the road curves towards the main site. Look for our sign. Starfest registration before July 1 is reduced by $10. See the Starfest website at

Aug  10 Wed: FQ

Aug 12 Fri: 07:26 Perseid Meteor Shower: Perseid Meteors are noticeable in our sky from July 17 through to Aug 24, so if you see a bright shooting star that seems to track from the head of Perseus, it was probably one of those, especially if it was fast. The peak night where 90 to 100 trails per hour are forecast is Aug 12 at about 9 am DST. Try viewing the night before or the night after, but note that the shower is over a month long and viewing around NM (Aug 2) will still be good. On peak night Aug 12, the FQ+2day-old Moon sets around 1:15 am so the sky is dark from then on.

Prepare for a cool/cold evening especially later in August when it can be very cool at night. The best way to observe is from your favourite lawn chair, a recliner preferably and wear a warmer jacket and head gear and perhaps lie under a damp-proof blanket or sheet.
Perseids are also famous for leaving persistent trains. Sometimes these will last for several seconds after the flash and once in a while they last for several minutes! If you have your binos handy, and can locate the trail, you can see them for a lot longer.
You can contribute to meteor science by keeping track of numbers of Perseids. Count how many are seen in a half hour, for ex. recording the start and stop time. More observers are better, and a circle of watchers can count the ones that a solo watcher would miss. Send your results in to John at and I will pass them on to those organizations looking for the info.

Aug  13 Sat:  BAS at Inverhuron Provincial Park -a public stargazing night. BAS members are asked to contact John H. if they can help out with telescopes. There is usually a big crowd if the weather cooperates and 4 or 5 telescopes are best so that there everyone can get a chance to see "Saturn, Mars and all of the stars!" (a gibbous Moon too).

Aug  18 Thu: FM

Aug  21 Mon: One Year Countdown starts to Solar Eclipse Monday, Aug 21, 2017. Check out the information under the 2017 SOL. ECLIPSE tab at the top of the HOME page.

Aug  24 Wed:   Mars 1.8° N of Antares; Saturn 4.3° N of Mars, Moon at LQ. This is the alignment of Saturn, Mars and Antares mentioned in SKY SIGHTS. Click the link to go there for all the details.

Aug  26 Fri: Grey Roots Public viewing (starts at dark). This public viewing night is weather dependant of course. If it is clear, we set up telescopes in the main parking lot at twilight around 9 pm or so. Above the western horizon, Venus and Jupiter are very close but in twilight. One day later they basically merge into a single point of light. Saturn and Mars in the southern sky are the feature planets and so are many of the nebula and clusters of the summer MW. BAS members usually have a variety of scopes for viewing. Public Welcome.

Aug  27 Sat: 16:53 Venus Jupiter separation 0.1° !!! See SKY SIGHTS for details of this very close approach of Venus and Jupiter. [In my 46 years of observing, they have never been this close! -ed]

Sep  1 Thu: NM: Annular Solar Eclipse (mid-Africa, Madagascar and into Indian Ocean). This is a less-than-perfect ring-type eclipse where the corona and prominences will not be visible (unless you are watching with an H-alpha telescope). No part of this, even partial phases are visible from Canada because it happens during dark hours in N. America.

Sep  2 Fri: Neptune at Opposition (magnitude 7.8) . At this time, the gas giant is closest to Earth and is visible all night long from sunset to sunrise. Located in Aquarius, Neptune requires a telescope to be seen.

Sep  3 Sat: Fox Dark of Moon viewing (BAS members and guests). If weather prevents observing, our backup night is Sunday (or even Friday night if weather looks poor for Saturday). Contact Brett T. or John H if you wish to be put on the alert list. Please park near the Learning Centre and follow the lane way between the barn and Centre to the ES Fox building. No vehicles are allowed at the observatory while we are hosting star parties. Bring a red flashlight if you have one.

Sep  7 Wed:  Regular Meeting at Fox Observatory at 7 pm: Beginner’s Astrophotography with the Mallincam and other cameras: Brett T. assisted by John H. We hope to have a live Mallincam viewing session during the second half of the meeting this night. The crescent moon will be on the viewing agenda as well as Saturn and Mars as well as the Messier objects in Sagittarius and Scorpius and other MW constellations.

Sep  9 Fri: FQ

Sep  16 Fri:     FM Penumbral Lunar Eclipse. Again not visible from N. America since it occurs over the eastern hemisphere. In any case only a very small part of the moon is eclipsed by the penumbra which is the almost invisible outer edge of the Earth's shadow. Don't make any travel plans as the view will not be worth it.

Sep  17 Sat:     HAPPY 5th ANNIVERSARY to ES Fox Observatory! Stay tuned for more news about a possible celebration of this anniversary.

Sep  22 Thu:    Autumnal Equinox 09:21. At this point the Sun has crossed the celestial equator and starts its trek to the southern extreme of its path in our sky. Summer is officially over and Fall has begun. Enjoy the colours and bug-free observing nights!

Sep  23 Fri:  LQ

Sep  30 Fri:    NM
