Jan 20/21, 2019 TOTAL LUNAR ECLIPSE!

The recent lunar eclipse was clouded out locally, but lots of BAS members and others were spread out across Canada and many found at least a short break in the clouds to capture one or more images. There were enough submissions to put together an additional page for the Feb StarGazerNews which will be available soon. Meanwhile, here is a composite taken of images off the monitor during a live view over the internet provided by Griffiths Observatory. Telescope there was a veteran 12 inch Zeiss refractor and it provided excellent views as the eclipse progressed through its various stages. The composite below used 7 frames at various stages and shows a view of the entire eclipse in one image.

If you missed this eclipse due to clouds where you were, you only have to wait until May 2021, a bit longer than usual, but then, we get another one in November the same year!

Comet Wirtanen finder chart (updated): Comet 46/P Wirtanen has now become circumpolar and is in the sky all night long. The Moon again be less obtrusive in the sky after Jan 28 or so when it becomes LQ so have a look and see if you can still pick it Wirtanen as a faint greenish glow. Wirtanen slows down in motion considerably in Jan, and the comet is well up in the sky by midnight and away from horizon turbulence. Chart below shows comet at 8 pm starting Jan 13 with daily markers after that until Feb 20. The bowl of the Big Dipper is at bottom and Ursa Minor is at left off the diagram.

Look to the Morning Sky for Planet Action
Venus is now spectacular as Morning Star and Mercury has now become a morning sky object as well. Jupiter has also re-appeared as a morning object and all three are visible before sunup this winter. Saturn replaces Mercury later in January when Mercury decides to return to the evening sky in February. Most of the planetary action has switched over to morning skies so look for nice groupings of the thin last crescent Moon with the naked-eye planets all winter.

One Bright Evening Planet and two binocular gas giants.
-Mars, Neptune and Uranus

Only Mars remains in the evening sky as a naked eye planet. Mars will hang high above the SW horizon (50°!) until June of next year as it is moving to the east about as fast as the sky is “moving west” on a daily basis. Seeing surface features on the planet is difficult now and it is shrinking in size as we separate from it. In June 2019, when Mars disappears into the solar glow, it is less than 10 arc-seconds across, less than half what it was at opposition. However, over the next several months, Mars can be spotted near first Neptune, (Dec 7) and then Uranus (Feb 12) so the Red Planet acts as a marker for those two less-observed planets. Might as well go for the two-for-one on those dates.

From Our Astrophotographers:

Comet Wirtanen Hanging in!
Frank Williams image below shows the green colour of Comet Wirtanen well in the image, but colour is not evident visually. Another observer reported seeing a faint tail (Lorraine R. Dec 29) and another (John H.) spotted it on two occasions (Dec 29 and Dec 30) in both 4 inch refractor and 9.25” Celestron Edge and did not see any tail or colour. The comet is fading fast, and no longer easily visible in binos but still right on track. It is now circumpolar (up in dark sky all night) and the Moon is less bright, so this is your last chance to spot 46/P. See updated finder chart below in Naked Eye/Binocular Events.

comet 46 Wirtanen 35 min dec 29

Frank Williams’ Dec 29 image of C. Wirtanen shows how much it has faded even in long exposure images. No tail was detected visually, nor in this 35 minute total exposure. Image above was a stack of several 1, 2, and 3 minute exposures taken with a Canon 6D through TEC 140 mm apochromatic refractor, ISO 3200, total exposure 35 minutes. Frank writes that the comet moved between exposures, so the stacking was not simple and required isolating the comet from the star field, stacking the comet images separately and then combining them again. He apologizes for the “artifacts” [I can’t see any…-ed].

Binocular Sights below and WEBLOG or VIS. COMETS have maps and more.

Whirlpool Galaxy!
Local astrophotographer defeats cloudy weather (again)!

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
