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 some heavenly views under one of the last truly dark sky locations in Ontario.
The BOEC was declared a Dark Sky Preserve in Nov. 2012, Canada’s 15th DSP. At the ES Fox Observatory, we have a large reflecting telescope (a 28-inch Webster) and we use it regularly in our public viewing sessions.


ROSETTA UPDATE: Oct 13, 2014

Oct 13: From

When the European Space Agency's Rosetta probe arrived at Comet 67P/Churyumov–Gerasimenko in August, one of the biggest surprises was the boulders: The comet's core is littered with them. Rosetta's OSIRIS camera photographed this specimen, a 45-meter-wide behemoth named "Cheops," on Sept. 19th:


On Nov. 12th, Rosetta will drop a lander onto the surface of the comet, and these boulders are a key hazard Philae must avoid.
But are they really boulders? "Maybe they only look like rocky boulders," says Art Chmielewski, the US Rosetta Project Manager at JPL. "Some scientists believe that they are 'flimsy' boulders. They may be more like dirty snow balls made in very cold weather. If so they are very fragile and would collapse under the lander. I hope Philae will
not find out if that is true."
Claudia Alexander, the Project Scientist for the US Rosetta Project says the boulders could be telling us something new about the way comets "sublimate"--that is, the way sunlight converts cometary ices into jets of gas. "I personally wonder if we've gotten the sublimation process understood in the reverse. In other words, instead of sublimation coming forth from a crack or fissure in the ground, sublimation emerges from cliff-sides, or 'spires' or vertical features, and then these features collapse when the vapor has been evacuated." Boulders could be debris from such a process.
"Obviously Rosetta is perfectly poised to make the measurements that will help us understand the physics of this process, and better understand cometary geology!"

Sep 30 Update
ESA Rosetta mission planners have selected November 12th, one day later than initially planned, for the historic landing of Philae on a comet’s surface. The landing on 67P/Churyumov-Gerasimenko will be especially challenging for the washing machine-sized lander. While mission scientists consider their choice of comet for the mission to be an incredibly good one for scientific investigation and discovery, the irregular shape and rugged terrain also make for a risky landing. The whole landing is not unlike the challenge one faces in shooting a moving target in a carnival arcade game; however, this moving target is 20 kilometers below and it is also rotating.

The comets listed below will all probably stay binocular objects.

Comet Jaques (C/2014E2) has now faded to around 10th or 11th magnitude and is presently in Aquila and getting lower in the sky in the west. Finder chart for Comet Jacques from Oct 1 to Nov 8 is HERE

Comet PanSTARRS (C/2012 K1) has entered the morning sky and is now visible at around magnitude 7.5 . It has passed out of Hydra into Puppis, the constellation just east of Canis Major. It is good early in late September during NM and also for the first two weeks of October because the brightening Moon will set before PanSTARRS rises in the pre-dawn sky. Finder chart for Comet PanSTARRS is HERE or on our Maps/Charts page. Note that both comets will be morning sky objects in the fall.

Comet PanSTARRS will be rounding the Sun in early August. Later in the month it becomes visible in the early morning hours before sunrise. More info for PanSTARRS can be found in our
WEBLOG and here: C PanSTARRS Universe today article.

Comet Oukaimeden (C/2013 V5)
This comet will become visible later in the year and into 2015. Predictions are that it will reach magnitude 5.7 or so around Sep 20, 2014. However the path of this comet keeps it near the Sun and it will be difficult to observe except for a few weeks in the early morning hours in late August and early Sep. Finder chart for Aug 14 to Sep 18 HERE:

Comet LINEAR (C/2012 X1) is fading and under magnitude 9 presently. Another comet, visible earlier this year, Comet Lovejoy, (C/2013 R1) has faded to below magnitude 11.
