Naked Eye/Binocular Astronomy Events


Summer, 2018
Venus -a Bright Evening Star in the West until Fall
Venus is now the only Evening Star in the west as Mercury slips behind the Sun in the first week of April. Venus at magnitude -3.9 far outshines any other object (except maybe the ISS on occasion) in the western sky.

Venus continues to track eastward and has passed the Pleiades continuing its trek into Taurus. By the end of May it has crossed into the centre of Gemini. Before the summer is over it will make a close pass at Regulus in Leo as well.



Three 3 am Planets Across the Milky Way
-Jupiter Opposition May 9
-Saturn June 27
-Mars July 27

If you are observing after midnight these mornings you have seen the preview of the summer sky with three planets strung across the Milky Way. In May Jupiter came up shortly after sunset and it reached opposition on May 9 rising at sunset, reaching maximum elevation at midnight (1 am DST) and setting at dawn. The jovian Red Spot is on the viewing agenda for the BAS Dark of the Moon viewing nights this summer. Next to clear the SE horizon is Saturn and its rings are well displayed by the time Mars rises an hour later. Saturn’s rings are tilted nearly the maximum they can be (26° in June and July). As summer progresses, Mars too becomes bright and prominent with the diameter steadily growing. It is about 15 seconds of arc across at the end of May and by Aug 1 will be 24.3 seconds. This is bigger than the disk of Saturn (which ranges from 15 to 18 seconds at opposition) but not as big as Jupiter (31 to 45 seconds across). Surface features on Mars will become detectable more easily this month.

From Our Astrophotographers:

Image below shows the spread of the planets Mars, Saturn and Jupiter along the ecliptic from Libra to Sagittarius that we see this summer. The Milky Way will be straddled by Mars (lower left) Jupiter (right at tree edge) and Saturn hiding above the Sagittarius teapot. This image was taken at the Bruce Peninsula National Park while BAS members provided views with telescopes to campers. Image taken on July 14, 2018 at 11:30 pm. The Webster-28 inch is in the dark below the green laser beam. Image by John H. with Canon 6D, 120 s ISO 6400, with 12 mm Samyang f/2.8 wide angle image.

Mercury Spotted July 14
Mercury made a faint appearance in the sky during the BPNP weekend as well. Three observers located it with binoculars just below the crescent Moon in deep twilight around 9 pm or so. Lorraine R. took this image with a Samsung smartphone camera (1/17s, f/1.9,foc.len. 3.7mm, ISO 200). Mercury appeared to have been captured on the camera (Canon 6D on tripod in image) but it turned out to be a hot pixel in the end.

Whirlpool Galaxy!
Local astrophotographer defeats cloudy weather (again)!
m51-11-hours--v3_630K

Frank Williams just keeps churning out the images! I know that each one is a lot of work having dabbled in it myself, but Frank has his workflow organized and keeps amazing us with the results. This image of M51 is possible since its location near the tip of the handle of Ursa Major is pretty much at the zenith right now at midnight and there is little atmospheric turbulence in that direction. In winter, M51 skims the horizon and there is no point in imaging or looking at it then. Do get out now and have a look with whatever telescope you have available.

Frank W. provides the following description:
This image is 11 hours with Canon 6d (modified) and cooled to -9C and a 12” F/8 RC *mallincam branded GSO truss scope (no field flattener) cropped to remove the ragged edges of stacked images. It is ~ 11 hours: 60 images 3 minutes each at ISO 800 and 159 images at 3 minutes ISO 3200 (found that cooled 6d is clean enough to increase the ISO). Calibrated, aligned, stacked and processed in Pixinsight. You can boost the saturation to your liking, but I have tried not to go overboard in processing. Many images of M51 (to my taste) are a bit gaudy.

BTW the [tiny] edge-on galaxy upper right [above the companion] is 230 Million ly away! M51 is only 30 million ly years away….

Auroral Displays

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). For more information click here: NOAA home website.

Current Auroral Oval not available right now
