CNYO Observing Log: The Winter Of Lovejoy – Green Lakes, Jamesville Beach, And New Moon Telescopes HQ – January 9 to 14, 2015

A re-post from the CNY Observers website (


Caption: Comet Lovejoy imaged on January 10th by the ever-impressive CNY astrophotographer Stephen Shaner. From his CNYO Facebook Group post: Last night was the first in over three months it was clear enough to shoot, but it worked out well because Comet Lovejoy is at its peak. Here's a quick process of about 40 minutes of exposures between 8-9 PM as it crossed the meridian. FOV is roughly three degrees. Distinct pale green coma in the eyepiece but unable to make out a tail or see it naked eye.

The 2015 skies are going to be full of comets. Well, at least six, to be exact, that will be either naked eye- or binocular-visible. That's still quite a few to those keeping track! The amateur astronomy community has taken heroic efforts to scientifically identify and track new comets in the last, say, 400 years. The rise of, for instance, the Panoramic Survey Telescope & Rapid Response System (or panSTARRS) as a method for finding and tracking both comets and near-earth asteroids (or, lumped together, "objects," for which you might hear the abbreviation "NEOs") has greatly increased the number of accounted-for fuzzy objects in our fields of view (and provided us a giant leap in our existential risk assessment infrastructure to boot). Quite simply, we've more + better eyes on the skies, meaning we're bound to continue to find more and more comets and asteroids. You can even subscribe to NASA twitter feeds that announce the passing-by of these hopefully passers-by (see @AsteroidWatch and @NasaNEOCam).

The discovery of NEOs may or may not qualify as a modern John Henry-ism, as amateur astronomers are still discovering objects at a decent pace thanks to improvements in their own optics and imaging equipment. Comet Lovejoy, C/2014 Q2, is one such recent example discovered by famed modern comet hunter Terry Lovejoy (who has five comets to his name already).

Comet Lovejoy And More In CNY

Comet Lovejoy has made the winter sky that much more enjoyable (and below freezing cold that much more bearable) by reaching peak brightness in the vicinity of the prominent winter constellations Taurus and Orion. Visible soon after sunset and before the "really cold" temperatures set in (after 10 p.m. or so), Lovejoy has been an easy target in low-power binoculars and visible without equipment in sufficiently dark skies. Now on its way out of the inner solar system, its bright tail will shrink and its wide coma (that gives it its "fuzziness") will disappear as the increasingly distant Sun is unable to melt Lovejoy's surface ice. Those of us who dared the cold, clear CNY skies these past few weeks were treated to excellent views, while the internet has been flooded with remarkable images of what some have described as the most photographed comet in history (a title that will likely be taken from it when a few other comets pass us by during warmer nights this year).

The first observing session around Syracuse this year happened at Green Lakes State Park on January 9th. Bob Piekiel, one of CNY's best known and most knowledgable amateur astronomers, had his Celestron NexStar 11 in the parking lot behind the main office, which was fortunately kept open for attendees hoping to warm up between views. To Bob's C11 was added my Zhumell 25×100's, providing less magnification but a wider field of view to take in more of the comet's core, tail, and nearby stars.

The Friday night skies were only partially on our side, offering a few short-lived views of the Orion Nebula and Lovejoy. Jupiter was just bright enough to burn through some of the cloud cover to our East, giving us slightly muddled but otherwise decent views of it and its four largest satellites for about 10 minutes. By our 9 p.m. pack-up and departure, the skies were even worse – which is always a good feeling for observers (knowing they didn't miss a chance for any additional views by packing up early).

The night of Saturday, January 10th turned into a much better night for observing, offering a good opportunity for some long-exposure images to try to capture Lovejoy just past its luminous prime. The following image was taken from one of the parking lots at Jamesville Beach – the same spot where Larry Slosberg, Dan Williams and I observed the nova in Delphinus. Light pollution aside from the 30 second exposure, the brightest constellations are clearly visible and a fuzzy, bright green star is clearly visible in the full-sized image.

The imaging continued in Marcellus on January 10th, with Bob Piekiel producing a zoomed in view of Lovejoy.

As with all astronomical phenomena (excluding solar viewing, of course), the best views come from the darkest places. A third Lovejoy session was had up in West Monroe, NY on Wednesday, January 14th with fellow CNYO'er Ryan Goodson at New Moon Telescopes. Putting his 27" Dob to use, the green-tinted Lovejoy was almost bright enough to tan your retina. With dark skies and no observing line, we then attacked some subtler phenomena, including the Orion Nebula in Orion, the Eskimo Nebula in Gemini, and the Hubble Variable Nebula in Monoceros. The images below are our selfie with Lovejoy and the best of Winter, a snapshot near the zenith (with Jupiter prominent), and the Northern sky (click on the images for larger, unlabeled versions).

A Clothing Thought…

As we can all attest to, the nighttime temperatures this month have oscillated between bitterly cold and painfully cold. The pic of my Element's thermometer at my midnight departure from West Monroe read -12 F (and the tire inflation warning light stayed on until I hit 81 South), yet with the exception of the tips of my toes, I wasn't very bothered by the cold.


2015jan22_nmt_layersIt's one of the cold realities of amateur astronomy – you never realize how cold it can get outside until you're standing perfectly still at a metal eyepiece. The solution is as old as the sediment-grown hills – layers! The top half of my outfit for the evening is shown below, featuring six (yes, six) layers from turtleneck to final coat. My bottom half featured three layers that decorum permits me from showing here. For those wondering how the blood still flows below the belt, the answer is simple – buy yourself an outer layer two or three sizes larger than you usually wear. In my case, my outer coat's a bit baggy and my outer pants are a very tightly-meshed pair of construction pants with a 40" waist (from a trip to DeJulio's Army & Navy Store on Burnet Ave. in Syracuse).

And don't worry about color coordinating. The nighttime is the right time for the fashion unconscious.

Some Light Science Reading. The Constellations: Draco

As first appeared in the May 2012 edition of the Syracuse Astronomical Society newsletter The Astronomical Chronicle.

Image generated with Starry Night Pro 6.

We return to our circumpolar constellation discussion begun with the Jan/Feb/March 2012 issue (our first "quarterly" report) by scaling up the Northern Horizon towards Draco the Dragon.

Draco, like all reptiles, is a bit on the dim side. Most of its constituent stars are in the 3 to 4.5 Magnitude range, making it an easy target in dark skies but a bit of a hunt near larger cities. If you've never looked for it before, it rivals Ursa Minor (the Little Dipper) in terms of "meh" apparent brightness in the sky (so it is far less pronounced than the Big Dipper or Cassiopeia, the two most prominent Constellations in this part of the sky).

Your best bet for identifying the stars in Draco may be to start right at the head and work your way down (and around, then over, then up, then way over the other way). One of my recent discoveries is that the head of Draco is, itself, a noted asterism (or noteworthy arrangement of stars that are not of the proper 88 Constellations) referred to as "The Lozenge" ("1" in the image above). I had been subconsciously thinking of Monty Python references to throw into this article and realized that saying "The Lozenge" several in a low John Cleese voice a la "The Larch" just about does it. The head of Draco is made from the brightest stars in the Constellation and does make for a reasonably easy target, as it sits between the two bright stars of the Little Dipper's bowl ("2" In the image at right) and Vega ("3"), the ridiculously bright star making its triumphant return to Spring skies (if you're at Darling Hill near sunset, you will see Vega as one of the first stars to appear above the Eastern Horizon well before it gets really dark). For those of you familiar with the Keystone (another famed asterism) that makes up the torso of Hercules ("4" in the image above), simply drive your eyes to the left-ish during the early night.

The historical origins of Draco as a lizard of any kind are localized to the Mediterranean, and these origins go back far enough that Draco is one of the Almagest's Original 48. The Greeks, and so the Romans, saw Draco as a Dragon (or, at least, lizard) of generally ill repute. Draco was seen by the Greeks as a guard of Hesperides' golden apples and/or a guard (or target, depending on how you read the sentence) of Jason's mythical golden fleece. The Romans saw Draco as the remains of the dragon killed by their goddess Minerva. It is perhaps fitting that, if you imagine Ursa Minor (the Little Dipper) as an ax on a questionably straight handle, then Draco is precariously on the celestial chopping block preparing to be cleft in twain.

The body of Draco is a healthy mix of single and double stars. In the boring single star category are Giausar, Thuban, and Nodus I. The double star list includes Edasich, Aldhibain, Altais, Rastaban ("eh mahn!"), Eltanin, and Grumium.

Thuban is one star in Draco to spend a bit of time on. In fact, it's one to spend several thousand years on. As late as 2700 B.C.E., Thuban held the place of Polaris as our North Star. The Earth may seem reasonably unchanging with respect to the seemingly unchanging arrangement of stars of our 100-year-ish lifetimes, but on the geological or cosmological timescales our Earth is as dynamic and fast-moving as that famed clay dreidel. The 26,000-year cycle we know as the precession of the equinoxes (shown above) is one of those processes that requires nearly the entire history of what we know as civilization to mark significant timespans for, but it is reported in several places that Thuban was of significance to the Egyptians in their building of the pyramids over 5 millennia ago (I would be happy to report that Thuban was the North Star that the main shaft of the great pyramid of Cheops was aligned to, but I've found conflicting reports online from otherwise reputable locations, so will simply report that the Egyptians very likely knew that this star appeared to move far less over the course of the night than any other and, therefore, held it with great regard).

For those observing at Darling Hill or anywhere south of Syracuse, Draco is a tough reptile to sustain one's astronomical appetite on. At least two comets are currently passing through Draco at the moment. One, LINEAR (C/2011 F1), is just off the Spindle Galaxy M102 (we'll come back to that) and, at 3 a.u. and closing, may improve beyond its apparent magnitude of 12.5. Draco also hosts Garradd (C/2008 P1) far beyond its tail star. At an apparent magnitude of 21.30, you have absolutely NO chance of seeing this comet from Darling Hill.

Draco is regrettably light on deep sky objects as well. The local color (at about 3400 light year) is provided by NGC 6543, known as the Cat's Eye Nebula (above). This is regarded as one of the most structurally complex nebulae in the Night Sky, although this complexity is only revealed through astrophotographic studies. NGC 5866 (below), also known as the Spindle Galaxy (which is very likely Messier 102, although some debate exists), is one of the great photographic sights in astronomy to my eyes. This edge-on galaxy view produces amazing density of material and spindly, fibrous clouds of dust and stars along the plane of the galaxy and a bright glow of stars all around this dense, dark line.

Now, the long curving body of Draco and its positions near the North Star does afford it one benefit in the Northern Horizon. Satellites! There are many bright (brighter than magnitude 4.0) satellites that follow paths over the Earth's poles, meaning those Constellations near the North and South poles are constantly getting pierced by manmade weather, communications, and "other" satellites. Simply letting my copy of Starry Night Pro go at high-speed with Draco at the center reveals over a dozen of these satellites over the course of just a few hours.
