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.

Naked Eye/Binocular Astronomy Events :
Crescent Moon and Mercury in West at end of March
Venus disappears below the western horizon by mid-March leaving Mercury to take over duties as Evening Star in the west. A lovely crescent Moon appears near Mercury March 29, then near Mars on March 30 and at the tip of the nose of Taurus on March 31. It will be a nice sight as it gradually increases its phase but earthshine should be prominent until FQ around Apr 4. Mercury does not last long in the sky. Mercury disappears first around mid-April and Mars will be in solar glare by the end of April and too close to observe by the end of May. Have a look at Mercury in a telescope, it should exhibit a crescent phase getting thinner and thinner rather quickly. Mercury viewing will last only a few weeks. Don't miss it.
The diagram below is from Starry Night c/o Simulation Curriculum and shows the crescent Moon on March 29, 30 and 31 about 8:30 pm DST. Sunset is around 7:50 pm DST so there is not much true dark sky before the group itself sets. A flat western horizon is highly recommended. Click on the image to download a copy.

From Our Astrophotographers:
Frank Williams latest submission to the "BAS Hall of Astrophotographic Fame" is an image of M17, or the Swan Nebula in Sagittarius.
"worked on Swan Nebula M17 during Starfest week from my little observatory in Allenford, and with cloudy weather here got to processing it. This has Luminance 1 hour, red filter 90 minutes, blue and green filters 75 min [using a] 140 mm TEC apochromatic [refractor] sbig STL 11000 camera cooled to -20c (As cold as I could get it running peltier cooler flat out). Processed in Pixinsight slight crop (to remove misaligned frames)".
All I can add is "WOW!"

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).
