BAS Observing Locations: (all locations are handicap accessible)

Observing happens mostly at the ES Fox Observatory (click for map) but there are other venues periodically. See the list below for location details.

Most o
bserving 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 months only and the washrooms are available at the Learning Centre (key required).

BAS Observing Events (dates listed below) 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: Most observing events at the Fox Observatory are open to the public (we gratefully accept donations to support our activities if you are inclined to do so). School-aged children are always free and welcome to attend with parents or guardians. Refer to each listing below for details. If you are coming from a distance we will try to accommodate you. Contact us by phone (519-379-7709) or email ahead of time.

BAS member impromptu observing also occurs at the Fox Observatory. To be put on the notification list email Brett T. at or John H. at
The list of Astronomy Events for 2017 is available here:
ASTRONOMY EVENTS 2017 -amended for Nov. There is a separate list of BAS events for 2017 available here: BAS 2017 Club Events (updated Aug 29)


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. However, BAS monthly (indoor) meetings occur rain or shine.

If skies are partly cloudy, check the ES Fox Observatory
Clear Sky Clock for weather prospects or call 519-379-7709 to confirm the event.

This list was updated Oct 8 and includes events to the end of Nov 2017.

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.

The next BAS meeting occurs on Nov 1, 2017 at 7 pm at the Tom Thomson Art Gallery.


Selected Astronomical and BAS Club events -Sep to Nov 2017:

(Times are in 24-hr format unless otherwise noted).

September 2017

Sep 06 Wed 19:00 BAS meets at Learning Centre classroom at BOEC . Solar Eclipse Recap -members images and stories.

Sep 15-17
Fri-Sun Inverhuron Dark Sky Weekend (contact John H. to register) free camping in return for public viewing on any clear nights during weekend.

Sep 16 Sat BAS Dark of Moon viewing (occurs at Inverhuron Park this weekend or individually at Fox for BAS member access only)

Sep 17
Sun 19:56 Venus 0.5°N of Moon: Venus is joined by Mars and Mercury in the morning sky for a nice photo opportunity. The thin crescent Moon is just under 7 degrees from Venus and Venus is only 3 degrees from Regulus. (Remember that star was right beside the Sun on Aug 21.) Below Regulus is the close pair Mars and Mercury only half a degree apart. Very nice! An even thinner crescent is between Regulus and the Mars/Mercury group the next night.

October 2017

Oct 04 Wed 19:00 BAS regular meeting 7 pm at Tom Thomson Art Gallery lower level. Tonight is a movie night, but there are still lots of stories to tell about the solar eclipse in August, so be prepared for BAS members to reminisce.

Oct 05 Thu 19:00 Venus 0.2° N of Mars.
This exceptionally close pass of Venus and Mars starts with the two planets 16 minutes of arc apart when they rise above the eastern horizon around 5:23 am EDT, and the two continue to get closer with a minimum separation of 12.5 minutes at 1:41 pm in daylight. Venus will be visible but Mars will be harder to see in daylight (though not impossible) since it is only 1.8 magnitude.

Oct 09 Mon 14:05 Aldebaran 0.6°S of Moon -occultation with Aldebaran and Moon below our horizon and not visible.

Oct 15 Sun 06:54 Regulus 0.2°S of Moon. Two months ago the Moon was occulting the Sun (solar eclipse Aug 21!) and Regulus was in the vicinity. This time our Moon occults Regulus from 5:48 am EDT to 6:30 am with the Sun in the next constellation over, Virgo, and below the horizon at event time, so it is still good and dark. Regulus is a blue star and an interesting contrast to the other star often occulted, Aldebaran, which has a reddish tinge.

Oct 17 Tue 06:04 Mars 1.8°S of Moon
17 Tue 20:21 Venus 2.0°S of Moon

Only the first event in the morning is visible in our morning sky. For the rest of the day, the Moon closes in on Venus but the group sets below the horizon so we do not see the close pass at 8 pm. Venus is over 6° below Mars and Moon in the dawn sky and all three are in Virgo.

Oct 19 Thu 13:00 Uranus at Opposition The second last planet in our current solar system reaches opposition tonight meaning that it rises at sunset and sets at sunrise. It is well placed all night long for viewing, so do go out and have a look. Magnitude is 5.68 and at higher power you can see a tiny disk at 3.7 seconds of arc across.

Oct 21 Sat 07:00 Orionid Meteor Shower
BAS Dark of Moon viewing night. As for good viewing conditions, if clouds stay away, this is a good meteor shower. Though numbers are not high, 20 shooting stars should be visible per hour once Orion gets higher in the sky. The Moon is a tiny 3% illuminated so there is no moonlight to hide the fainter shower meteors. The radiant is in the feet of Gemini at Orion’s club and is well up in the East by midnight or so. As for all viewing nights this time of year, come dressed for cold and dewy nights. A nice reclining lawn chair is perfect for meteor watching and bring a damp-proof cover to stay warm under.

Oct 24 Tue 07:54 Saturn 3.3°S of Moon. This is a nice view with Saturn and a 5 day-old crescent Moon in the Milky Way between Scorpius and Sagittarius.

November 2017

Nov 01 Wed 19:00 BAS regular meeting 7 pm at Tom Thomson Art Gallery lower level. Tonight is a members’ night, so there is no telling what interesting things will come up. Members are asked to contact John H. to reserve a 10, 15 or 20 minute slot ahead of time.

Nov 05 Sun 02:00 Eastern Standard Time begins. Set your clocks back one hour. Note that at 8 pm Eastern STANDARD Time later today, there is an occultation of Aldebaran by the Moon.

Nov 05 Sun 21:19 Aldebaran 0.8°S of Moon Another in the continuing series of occultations of Aldebaran by the Moon. Look for it to disappear on the bright Moon edge at 8:05 pm or so. Times can vary by several minutes depending on where you are located, so run a planetarium program like Starry Night or Sky Safari with the program set for your specific location to get your exact times. Reappearance occurs around 9:00 pm (Owen Sound) and Aldebaran will pop out into view in dark sky since the Moon is just past full and the trailing edge is in darkness.

Nov 13 Mon 01:00 Venus 0.3° N of Jupiter The two brightest planets in the sky get real close in the morning sky reaching minimum separation while the pair are still out of view. By the time Venus and Jupiter clear the eastern horizon, they are 17 min 11 seconds of arc apart and this slowly increases as twilight progresses. Both should be visible during daylight hours but a GOTO scope will help to locate them. The moons of Jupiter will be nicely lined up as shown on the diagram from Set Safari below showing the group at 6:05 am EST Nov 13 when they are less than half a degree above the horizon. The sky will brighten as the pair gets higher, but these are bright planets and should continue to be visible as light levels increase.

Nov 17 Fri 12:00 Leonid Meteor Shower peaks. This is an off-year for the Leonids and expect only 20/hour, but the Moon is pretty much absent from the sky (only 1% illuminated) so this is a good year to view Leonids since moonlight will not interfere. The Leonids parent comet, Comet Temple-Tuttle, has left a trail of debris and every 33-34 years, Earth encounters the main mass of dust and we get a Leonid storm of several thousand meteors per minute! That last happened in 1966, then a more subdued storm at the end of the millennium. Our next storm is predicted for sometime around 2031-32. [I can hardly wait!]

Nov 23 Thu 19:00 Mercury at Greatest Elongation: 22.0°E. Look for Mercury in the evening sky after sunset for most of November. It gradually climbs higher towards Saturn which is sinking into west all November. On the 28th Mercury is about 3 degrees from Saturn at sunset and both set at the western horizon around 6 pm.

A list of ASTRONOMY EVENTS FOR 2017 is available here: ASTRONOMY 2017 (amended for Nov). Note there are three events that have been added to the November listing due to an omission in the original listing.
