General Info: PLEASE READ
Note: Observing is weather dependant -see Weather Information note at right.

Meeting Locations: (not weather dependant)
Note: We are back at Grey Roots Museum for the remainder of 2015.

Meetings happen at 7 pm at
ES Fox Observatory (June 3, July 8, Aug 5 and September 2 only in 2015) (washrooms are available) (map)
Grey Roots Museum (map) Meeting Room Side Entrance (March 4, April 1, May 6, October 7, November 4, December 2) (washrooms are available)

Observing Locations: (all locations are handicap accessible)

Our events usually happen at either the ES Fox Observatory (click for map)
or the
Grey Roots Museum (click for map) parking lot.

observing locations are “remote locations” meaning there are NO permanent on-site washroom facilities. A portable washroom is locaed 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.

To help with your observing plans with regard to moonlight, check the dates for moon phases given in the listing. Best observing occurs during NM and LQ. FQ and FM are times when the Moon brightens the sky so fainter objects are not as easily seen. Planets are usually visible even during FM nights.

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 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 Nov 23 for Nov and Dec 2015 events .

Note: BAS meetings are NOT held in January and February but impromptu observing sessions continue at the Fox Observatory (at BOEC) . 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 November 2015 to December 2015:

BAS meetings are held at the Grey Roots Museum or Fox Observatory and impromptu observing continues at the Fox Observatory on an individual or small group basis.

2015 Events Summary



Nov 3 Tue LQ and Mars and Venus conjunction in morning sky less than 1 degree apart. Last event of the grouping of last month. Mars, Venus and Jupiter now spread apart for the rest of the year.

Nov 4 Wed BAS meeting at Grey Roots Museum Topic: Members night/Gadget Night

Nov 7 Sat Venus, Mars and Last Crescent Moon appear in a nice 2° triangle below Jupiter in the dawn sky. zJust about the middle of the triangle is Zavijava, a 3.6 magnitude star in Virgo. A great photo opportunity of the weather cooperates.

Nov 11 Wed NM Remember to get your poppy and wear it today.

Nov 26 Aldebaran Occultation
The last such event for 2015 is a nighttime event but involves the moon just a day past full which makes it difficult to observe the events at the bright limbs. Disappearance at 5:38 am EST at the bright preceding lunar limb, reappearance is at 6:28 am EST but there may be a thin dark limb at the emergent point. Reappearance might be easier to spot than the disappearance. The elevation of Moon changes from 22° to 14° as the night goes on and Aldebaran is out of view for about 50 minutes -time enough to go for a coffee...


Dec 2 Wed BAS meeting at Grey Roots Museum Topic: Christmas wrap-up and recap of 2015

Dec 7
Comet Catalina US10 appears near Venus in the morning sky. The Venus - Comet separation is 4.5°, and right nearby is a thin Last Crescent Moon about 2° from Venus. You shoud start looking for Catalina in late November as it rises above the eastern horizon about this time. Comet brightness should be about magnitude 5 when it finally appears in the northern hemisphere. Note that it is on a track that will take it towards Arcturus with a very close pass to that star on Jan 1, 2016. The separation will be less than half a degree! What a way to celebrate the New Year!

Dec 7 Daytime Occultation of Venus
The last lunar occultation of a planet for 2015 occurs in daylight for Bruce-Grey and once again requires a GoTo alignment of your telescope the night before, unless you want to chance finding a thin crescent moon in daytime. The Sun and Moon are about 42° apart at disappearance on bright limb: 12:28 pm EST. Reappearance at 1:32 pm EST. The Moon is 3 days before new and is still 11° high when Venus reappears. Venus is occulted for 65 minutes, so again there is time for a coffee break.

Dec 11
Fri NM

Dec 14 Geminid meteors
peak at 120/h during daylight (1 pm) but the viewing on the nights of Dec 13 and 15 should be close to that number. There is only a thin crescent Moon brightening the evening sky so both nights should be good for meteor watching. Remember to dress for the weather. This may be the last BAS event for the year at the Fox Observatory, which does have amenities like a coffee machine and a warm room.
