BAS Observing Locations: (all locations are handicap accessible)
Observing happens mostly at the ES Fox Observatory (3092 Bruce Rd 13) 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) at other times.

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: Observing events at the Fox Observatory are open to the public on public viewing nights ONLY. We are not open during weekdays or evenings during the school year. Refer to each listing below for details. School-aged children are always free and welcome to attend with parents or guardians on public nights. Contact us by phone (519-379-7709) or email ahead of time. Donations to support our activities are gratefully accepted.>
BAS member impromptu observing also occurs at the Fox Observatory. These are restricted to current members who must notify the organizer that you are coming. Members wishing to be put on the notification list please email Brett T. at or John H. at
The list of Astronomy Events for 2018 is available here:
ASTRONOMY EVENTS 2018. There is a separate list of BAS CLUB events for 2018 here: 2018 BAS CLUB EVENTS


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

May 2018

02 Wed 19:00 BAS meeting at 7 pm back at OSDSS Bailey Hall in Owen Sound. Floorplan here: Bailey Hall. The speaker for the May meeting is Steve Irvine (“Finding My Way in Astrophotography”) showing his favourite night sky images many of which have appeared in Sky News and other national magazines, including National Geographic. Download a complete listing of our BAS club events here: 2018 BAS Club EVENTS. if you wish a preview of future sessions.

After May 2, BAS meetings are at the Fox Observatory Jun 6, Jul 4, Aug 1 and Sep 5. Meetings Oct to Dec will likely be Bailey Hall again but this is to be confirmed.

May 08 Tue 19:00 Jupiter at Opposition (magnitude -2.5!) Jupiter at opposition is closest to Earth and hence largest in our sky for a month or so either side of May 8. This is the best time to look for features in the atmosphere of this gas giant like the Red Spot , festoons, and barges.
Note that our Dark of the Moon viewing night May 19 features the Red Spot which will be centered on Jupiter that evening.

May 19 Sat 20:00 Dark of Moon @Fox (Jupiter Red Spot; Saturn viewing around 2 am) Jupiter’s Red Spot will be visible most of the evening after dark and if you stick it out to 2 am or so, Saturn and her rings will be visible once the planet clears the murky air and trees above the eastern horizon. Dress warmly as this will be a cool night but hot chocolate and coffee will be available. Please park at the Learning Centre parking lot and walk to the observatory.

26 Sat 20:00 Gibbous Moon Viewing/Imaging Night @Fox Bring your cameras and scopes to the Fox for a night of Moon gazing and imaging with our resident Moon “lunatic” John H. Cell phones are welcome and do a nice job of imaging the Moon with very little fuss.

27 Sun 20:00 Venus just misses 3rd magnitude ε-Geminorum (Mebsuta) this evening above the western horizon. The pair sets at 11:30 pm EDT so there is lots of dark sky time to watch Venus glide by. This star was occulted by Mars in 1976. Planetary occultations like this are very rare and you are lucky to see even one in your lifetime. Next Venus occultation is in 2035 and you need to travel to see it. The 16 minute separation of Venus and Mebsuta on May 27 is a nice view nevertheless. Start watching at dark and in the hour or two before they disappear, you can see the separation due to the motion of Venus change from 16 minutes 9 seconds to 16 minutes 3 seconds when they set.

June 2018

Jun 02 (Sat) 20:00 Star talk and viewing at Huron Fringe Birding Festival at MacGregor Pt. Prov. Pk.
Contact John H at if you can help out with a telescope for the viewing after the talk. Venus and Jupiter are early evening targets for viewing, weather permitting.

Jun 06 (Wed) 19:00 BAS meeting
at 7 pm at ES Fox Observatory at the Outdoor Ed Centre near Wiarton (MAP) . Speaker is Mike Reid, (via Skype) from the University of Toronto Astronomy Department. His topic is “Life in the Cosmos”. Come dressed for the weather since the Fox Observatory is not heated and if weather permits, there is observing after dark. Bring lawn chairs and bug spray as well.

Jun 09 (Sat) 21:00 Dark of the Moon viewing at Fox Observatory. Public welcome. The prime target tonight will be Jupiter and its Great Red Spot (GRS) which will be crossing the Earth-facing side of the planet tonight in the early evening. Venus will be the first “star” visible after sunset, and Saturn is also a viewing target but not till around midnight or so. It will be better towards the end of the month and in July, becoming higher in the sky earlier in the evening.

Jun 21 (Thu) 05:07 Summer Solstice occurs today.
The traditional celebration at Keppelcroft/Keppelhenge at Big Bay takes place from 11:30 am to 1:30 pm. The maximum elevation of the Sun (solar noon) occurs at 12:25 pm and the shadow will be its shortest at this time. Bring lunch and sunscreen and enjoy the first official day of summer, -this is a public event. Solar observing with both white light telescopes and H-alpha solar scopes will be provided, but don’t expect much in the way of sunspots on the Sun since we are in a solar minimum right now and for the next few years.

Jun 27 (Wed) Saturn is at Opposition. The ringed planet reaches opposition tonight when it rises in the east at sunset and sets in the west when the Sun rises in the morning. Saturn viewing is good for a month or more before and after opposition but even in the fall, Saturn will still be seen above the horizon in the western sky. Rings are tilted a maximum 26° or so and the planet shines its brightest at magnitude 0.0.
