Spring is Realm of Galaxies Time!


Frank Williams sent in this spectacular shot of M81, a galaxy in Ursa Major. Also in UMa, near the tail star, Alkaid, look for M51, the Whirlpool Galaxy. In Virgo and Coma Berenices, the Realm of Galaxies are in the best position (highest in the sky) this time of year as well. Go galaxy hunting, (at least until the cluster and nebulae of the MW are back)!

Say Goodbye to Orion.

Aaron Top sent in this image of the Orion area showing all the interesting nebula visible in the vicinity of this winter constellation. Check out Barnard's Loop, the Horsehead gas cloud and the Rosette Nebula near the left edge. The colours of Betelgeuse and Rigel (red/blue) also are obvious in this image. Orion is still visible but it is fast receding into the western horizon, so have a look while you can.

The Bluewater Astronomical Society is a group of amateur astronomers that love stargazing and sharing the hobby with others. We promote astronomy education in the Bluewater counties of Bruce and Grey by holding star gazing sessions, lectures and astronomy events for anyone interested in learning more about the night sky. We have a large, modern facility, the ES Fox Observatory on the grounds of the Bluewater Outdoor Education Centre of the Bluewater Education Foundation. There we show, to young and old alike, views of the moon, planets, star clusters, galaxies and nebulae. Join us at our public stargazing sessions (see below or click on COMING EVENTS for dates to have some heavenly views at one of the last truly dark sky locations in Ontario.

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.


Comet Lovejoy continues to be visible throughout April and May.

Check out the close pass to Polaris on May 28!

Featured Comet:
C/2014 Q2 Lovejoy – still hanging in at magnitude 7.

Since the first observation of Comet Lovejoy by BAS members on Jan 13, it has continued to be present in the sky. Now, it's the "oh yeah" comet as in "Oh yeah, it's still there!" The most recent observation was prompted by a binocular view by one of the observers at the Fox Apr 18. Then we had a look at it through the 28-inch Webster and a faint tail was still detectable. The finder chart is available here: (finder chart to June 3 HERE), or click on the diagram above. Current magnitude is 7 and dropping but very slowly.

A good article from Sky & Telescope is here:
and here for a more recent article:

Our Next GREAT COMET is overdue!
Tim Reyes writes for His most recent piece is an excellent article called "When is Our Next Great Comet?" An interesting read!

OTHER COMETS (potentially) VISIBLE IN OUR SKY Right Now:

Comet PanSTARRS C/2014Q1 coming this summer for a brief showing maybe magnitude 2! More coming...

Comet Catalina C/2013/US10 in last part of 2015...another Christmas Comet...stay tuned.

Comet Master C/2015G2 is a new comet now at magnitude 9 and expected to brighten to 6 in May. For up-to-date information on all the recently discovered comets, check this excellent website: .

Screen snap below is from Seiichi Yosida's website (link above) and illustrates the brightest comets in the sky presently. More information including brightness prediction graphs are found at the website. All graphics and information is by Seiichi Yoshida. (Screen snap below was obtained Apr 22).

EVENTS May 2015 to July 2015

BAS meetings are now back and impromptu observing continues at the Fox Observatory on an individual or small group basis. To be put on the notification list email John H. or Brett T. at More details about the following events can be found in COMING EVENTS. Some of the more interesting sky events are also described graphically in SKY SIGHTS.

Re: Comet Lovejoy:
Comet Lovejoy continues to be visible this month and into May as it crosses Cassiopeia and heads up towards the Pole Star. It is now circumpolar and does not set below the horizon all night. The Moon is full in the first week of May but it brightens the sky less and less in the latter half of the month. Lovejoy has declined in brightness but is still visible on binoculars and medium to large telescopes. See Comet News above for more info and links to finder charts.

BAS meetings have resumed at the Grey Roots Museum at 7 pm. Regular BAS meetings happen the first Wednesday of the month from March to December. Please enter the meeting room at the west doors (nearest the pioneer village) because the main part of the building is not accessible to us.
Meetings usually consist of a short business meeting and include a speaker or presentation on an astronomy topic. See the meeting dates below for more details. Contact for more information.

Note that this year, since Canada Day falls on the first Wednesday of July, the BAS meeting will be the second Wednesday in July, i.e. July 8 and will occur at the ES Fox Observatory. The June, July, August and September BAS regular meetings will be at the Fox Observatory. All others occur at the Grey Roots Museum.

[Note: Canada Day is July 1 and not June 1 (as previously listed and the BAS meeting is on July 8 not June 8). Our sincere apologies for the error. ]

More Details for the events listed here can be found on the COMING EVENTS page. A full list of the remaining events for 2015 is provided here: 2015 Events Summary Note this list changes from time ot time as dates are confirmed, etc.
