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.
Mars has been tracking across the sky towards Saturn and Antares and finally is passing through the gap. By mid-September it is in the Milky Way and appears in front of the millions of stars of our home galaxy centre. Look for it just below the Lagoon Nebula in the last week of September.

Naked Eye/Binocular Astronomy Events :
Perseid Meteor PEAK of 180/hour predicted for Aug 11-12!
More here: EARTHSKY.org
There is a prediction from meteor specialists of a possible peak of 200 Perseids per hour in the dawn hours of Aug 12. It may last a few hours and Aug 11 after midnight (Aug 12 am) is favoured. If your skies are clear, it will be worth a look! And also try the night before and after as the shower actually continues for several nights.

May 9: Mercury Transit SUCCESS!
Special Issue Here: Mercury Transit 2016
May 9, 2016, dawned with clear blue skies that lasted all day long! The silhouette of Mercury passed in front of the Sun and BAS members, elementary students on program at BOEC and their adult chaperones watched the event from the Fox Observatory. Images presented here are from various members who took the time to snap a picture while others were busy with observations. Actually the event was slow enough that there was no rush. The die-hards who watched the whole event are shown in the first image below. Mercury Special Issue available by clicking on cover page here.
Mars continues (relatively) big and (still) bright:
Mars reached opposition on May 22 and is the brightest and largest in our sky in the last 2 years. At best, it will be almost as bright as Jupiter at mag -2.0 (presently, Aug 1, it is -0.7), Mars is found near Antares and Saturn in Scorpius. It is largest and brightest at opposition, when Mars is opposite the Sun in our sky and is highest at midnight, but good viewing can be had a month before and after. In the diagram below note how large the planet appears -the disk is about the same as the disk of Saturn at the end of May. With a telescope you can make out features on the surface of Mars like the polar ice caps. There is excellent and detailed information at the ALPO site here: 2016 Mars Apparition
Also Brian Ventrudo, has a very detailed Mars observing guide at this site: Mars Observing Guide
Saturn in Scorpius:
The famous Ringed Planet is also in prime viewing territory less than 20° east of Mars. Make sure you take a look at it with your telescope. The rings are tilted as fully as they can be to our line of sight and just like Jupiter, Saturn has a retinue of moons that can be seen around the planet. Five can be seen with medium sized telescopes and range in brightness from 8.4 to 11.8; Titan is 8.4, Rhea is 9.7, Dione is 10.4, Tethys is 10.3, and Enceladus is 11.8. Watch Mars slip between Saturn and Antares on Aug 24/25.
Sky and Telescope’s informative viewing guide to Saturn is here: Saturn Viewing Guide
Jupiter Watching -Catch it before it is GONE!
Jupiter watching continues and if you need to bone up on the King of Planets try Brian Ventrudo’s informative article here: http://cosmicpursuits.com/575/observers-guide-to-planet-jupiter/
Jupiter is past opposition but it is still reasonably high once it is dark. By the end of July it is setting in the west before 10:30 pm, but even in twilight, Jupiter is a fine sight. There is no excuse for not having a look at it and its contingent of moons before you start on the other objects farther to the east. The Red Spot has taken on a fine reddish hue which makes it stand out even more than usual. You will have no trouble seeing it (if the planet's rotation brings it into view. And in August, Mercury and Venus are in the same part of the sky, so there are three planets to hunt for in the West after sunset. See SKY SIGHTS for more.

From Our Astrophotographers:
Frank Williams continues doing some excellent work capturing astronomical targets. His latest is the leo Triplet below. Frank is now using a CCD camera (SBIG STL 11000) with colour filters RGB.
This is a total 1.5 hour exposure that was taken through his 5-inch TEC refractor. Impressive. This image was taken May 6 and by cosmic coincidence a supernova erupted in M66 (galaxy centre left side) about 2 weeks later so Frank missed getting to be the discoverer! See this site for more on the M66 supernova: M66 SN
The countdown to the Great Aug 21 2017 Solar Eclipse continues:

ES Fox Observatory Clear Sky Chart
BACK TO TOP
Auroral displays in our area are declining as we have passed solar maximum. There have been periods of "blank Sun" where sunspots have been totally absent for a time. However, at far northern and southern latitudes near the auroral ovals, sometimes magnetic disturbances from the sun produce auroras even without visible sunspots. So if the auroral oval in the graphic below is showing an intense RED, aurora borealis may be visible from your location. The graphic is updated regularly with time indicated at the top in UT so subtract 5 h to get local EST, or 4 h for DST. (Use the appropriate factor for other time zones).
