CNYO Observing Log: Transit Of Mercury, 10 May 2016

Poster’s Note: A post from mid-May of this year never made it to the website. Posting now for the 2016 observing record.

Greetings, fellow astrophiles!

The real-time global observatory that is the internet has made available to everyone, all the time, every particular astronomical event that occurs anywhere. That said, it’s always more fun to be able to turn the computer off and point a telescope to the sky to see something with your own eyes.

2016may12_Mercury_transitOur side of the planet was treated to one of the great joys of terrestrial observing – a transit of an interior (to us, anyway) planet across the face of our closest star, the Sun. The downtown Syacuse crowd for the Venus Transit in 2012 peaked at close to 350 people (far larger than the 2006 transit crowd of 10!) and was one of the best documented astronomical events in CNY thanks to local news reporters. The Transit of Mercury this past Monday, May 10th was comfortably smaller, perhaps proportional to the significantly smaller black spot that Mercury makes as it passes across the Sun. A wealth of access to internet and space science resources, however, has left some excellent lasting records of the event for us to enjoy (such as the picture at right, courtesy of Bob Piekiel.

2016may12_20308482_bob_largeWith the usual thanks to Glenn Coin at for promoting astronomy events here in CNY (and for taking the pic at right of Bob in action, click for a larger view), local folks were made aware of the Syracuse and neighboring sessions (see link). Schenectady, Hamburg, Rochester, Binghamton (thanks to our friends at Kopernik Observatory), and Marcellus (thanks to Bob Piekiel) were all on the docket. Those stuck at the office were made aware of viewing opportunities online thanks to an Associated Press post at as well (see link).

Glenn Coin took the trek out to Marcellus for Bob Piekiel’s session. His write-up can be found at:

Bob Piekiel reported the following:

Chris [Schuck, fellow CNYO-er] and I kept them busy at the transit program this morning. Lots of folks mulling around with questions, cell phone cameras, and non-stop desires to see the view every few minutes. Skies were near perfect, with only a few clouds. Also, got some nice views of Venus, only 8° from the sun. Venus is so far away it is only 11 arc-seconds in size, compared to Mercury’s 10 arc-seconds. They both look about the same size in the scope, but one is white, the other was black!

Freshly displaced to Rochester, I enjoyed the start of the transit from Farash Observatory, home of the Astronomy Section of the Rochester Academy of Sciences.

2016may12_davedaveI arrived at Farash Observatory with my Coronado PST in tow (in a small plastic box, that is) around 7:00 a.m. in time to set up, chit-chat with two Dave’s (manning the live stream in the image at right), Doug, and Bob, and catch the very start of the transit (by dumb luck at that. I started observing a minute before just to get things lined up and zoomed in). All were thrilled to see Mercury begin to transit at the same point that a bright prominence had grown (I overheard someone say “looks like Mercury’s got a tail”). ASRAS provided live streaming of the event on youtube through a CaK on the Farash grounds, then the dozen-or-so folks there early cycled through everyone else’s scopes for varying H-alpha and white light views of the transit. The transit through a solar-safe 16” Cave is quite impressive(!), with Sunspot 2542 visible below Mercury (below in the eyepiece and the flipped-around view the Newtonian scopes provide). Once home, I did what the majority of us were doing – checking NASA streams and the local club feeds for more sights until the transit’s end at about 2:42 p.m.

My own poor attempt at astrophotography (with an iPhone 6s and through the ASRAS 16″ Cave) is shown below, including a slightly smudged Mercury at upper right and Sunspot 2542 at lower right. For proper orientation, see the official NASA SOHO image of the Sun at its image repository (link here).


163186109.kpdILVVp.mercury_transit_4A few others with a bit more patience (and a bit more money) really made the transit memorable with some fantastic movies. One .gif passed around on Facebook is shown at right from Tom Polakis using a Lunt 100 (click for a larger view) that shows the tail end of the transit. This is the kind of stuff amateurs can do from their backyard with a good scope and a decent camera (wait for the 4.2 MB .gif to load. It is definitely worth it)!

On the other hand, those with a much larger budget can put telescopes into space and produce the following video – courtesy of NASA’s Solar Dynamics Observatory (SDO). Collective thanks to all for their tax dollars in bringing images like this to the masses.

Now we’re talkin’.

For those interested in taking in a more unobstructed view of the Sun, the next scheduled solar observing sessions in the Syracuse area are also being provided courtesy of Bob Piekiel and his considerable solar scope collection. The first is August 13/14 (Sat/Sun) at Clark Reservation, then August 27/28 (Sat/Sun) at Baltimore Woods.

We hope you don’t wait until another transit to take in some proper solar viewing!

CNYO Observing Log: Attempted Observing, Successful Lecture, And Maker Hall Session For January, 2016

Greetings fellow astrophiles,

A brief summary of events already had in January. For the most part, this is the time of year when most activities slow to a crawl (unless you’ve got a good few pairs of thermals to wear, in which case you’re observing is limited by conditions and the build-up of water vapor as you breath too close to an eyepiece).

Solar @ Green Lakes, Nighttime @ Baltimore Woods, January 9th

With the Friday night session a complete wash at Baltimore Woods, Bob Piekiel and I ran a double on Saturday, January 9th. The first event was a solar observing run at Green Lakes State Park (amid current construction around the main building). Sadly, this was the best-attended failed session yet, with considerable cloud cover only providing the most fleeting glimpse of the Sun before taking it away again. Attendance peaked near 25, though, which is great news otherwise. Bob will be running (and I wing-man’ing) a few more solar sessions, for which we hope the skies agree at least once.

I am pleased to mention that, near the end of the session, a few mountain bikers came by the scopes to ask what we were looking at. When I said it was a failed solar observing session, one of the bikers (in an SOS shirt) mentioned that he had learned some observing with “A guy named Stu.” Taking a few minutes to remember local amateur astronomer extraordinare Stu Forster was a treat that made my otherwise overcast day.

Later that night, during what was maybe-sort-of predicted to be an opening in the sky from 7 to 8, Bob and I waited patiently at Baltimore Woods for his monthly New Moon weekend session. We went with hope, then left with 90 minutes remaining in the session as the cloud cover only got worse-and-worse. Our loss was other’s gain, of course – as we’ve had a few previous January sessions that were painfully cold but clear. 2016 has started warm but painfully cloudy.

Ceres & Pluto @ DPL 4 CNY Skeptics, January 21st

The lecture given at DeWitt Community Library for our fellow science-minded friends in CNY Skeptics was a repeat (mostly) of the Ceres & Pluto lecture given at Liverpool Public Library late last year. With a few new pics and the benefit of one full pass of the lecture, this session went fairly well (minus at least one softball-stump-the-speaker question). Plans are already in the works for a few more lectures, including one at DPL for the non-affiliated library audience.

TACNY Maker Hall @ The Dr. King Community Celebration, January 30th

This past Saturday, CNYO hosted a strategically-placed table to talk astro-shop for a third MLK Community Day Celebration in a row (with continued thanks to STEM Superstar Mary Eileen Wood for the invitation to the event at Nottingham High School). With brochures, Prof. John McMahon’s graciously donated table-top scope (and a 38mm eyepiece to be able to get *anything* into focus in the background), Mars and Ceres pebbles, and a gyroscope in tow, we had about 50 kids and adults stop by over the course of the 2 hour 30 min event. Directly behind us, Dr. David Wormuth made a guest appearance and put his surgical skills to the test (well, not really) in a live demo for the attending audience.

CNYO Observing Log: A Summary Of The Last Few Months Of 2015 In Rapid Succession

Greetings fellow astrophiles!

In the interest of full documentation of the year’s events (but because we’re running short on time), a brief post summarizing all of the unsummarized Observing Logs for the past few months (we’re done with observing for 2015 unless something really interesting happens tomorrow night!). Despite mostly unfavorable conditions, we did manage to get a few decent sessions in.

Mid-to-Late 2015 Library Lectures

1. Hazard Branch Library, Syracuse – 20 June 2015

In advance of International SUN-Day on June 21st, CNYO hosted a combined solar astronomy lecture and nearly clouded-out observing session. Provided the sky is clear (which was mostly NOT the case for the 2015 SUN-Day festivities), we’ll be running a session for International SUN-Day 2016 somewhere around town.

2. Seymour Library, Auburn – 6 October 2015

A “general introduction to astronomy” lecture was the staff request for this session, including a bit about getting around the CNY Nighttime Sky (courtesy of CNYO’s handy-dandy brochures) and a little sneak-in of the New Horizons (Pluto!) and Dawn (@ Ceres!) missions. For the record, one of the aesthetically pleasing libraries in CNY.

3. Liverpool Public Library, Liverpool – 23 November 2015


After a rescheduling of the October 22rd lecture due to pending social obligations, CNYO returned for our twice-yearly (or more) LPL lecture, featuring a more complete session about Ceres and Pluto and all that it means to be dwarf planets in our always-interesting Solar System.

4. CNY Tech User Group @ LPL, Liverpool – 7 December 2015

CNYPCUG (but by “PC,” they mean “Tech”), which meets monthly at LPL, saw the announcement for the November 23rd session and asked for a tech-centric lecture of their own. Mixing up some of the recent dwarf planet discussion with the flurry of missions already active (with an extra emphasis on Hubble imagery), this session ran over 90 minutes and had lots of good discussions to boot.

Late 2015 Observing Sessions

2015 wasn’t a truly bad year for observing, but trying to get clear skies, little-to-no Moon, and short-notice organizing all together for some of our hoped impromptu sessions just didn’t work out too well. The four official sessions on the books are listed below.

1. Total Lunar Eclipse @ Baltimore Woods – 27 September 2015

This, THIS session was a treat. Driving out to Baltimore Woods around 8:00 p.m., the sky was completely overcast with only a few patches of anything clear-like in the distance. Within 5 minutes of BW, however, the sky just opened right up, with some of the last cloud cover making for some excellent final views of the obscured Moon before the whole sky went clear. Over 50 people were at the session, which culminated in a beautiful full lunar eclipse.


The best part of the whole session – and the one I made mention of for people to take a second look – was just how bright the restive the sky becomes when the Moon is dimmed so significantly. One could have had a full New Moon observing session, complete with galactic views and all the subtle highlights one could wish for, all while having this dark orange/red Moon *right there* in the sky. Bob Piekiel was kind enough to make a montage of the event, which I include above (click for a larger view).

2. North Sportsman’s Club, West Monroe – 10 October 2015

This session was mostly organized on our Facebook Group and even received a small but active (8) attendance (including a guest appearance by New Moon Telescope’s own Ryan Goodson) despite a clerical error in the organization itself not allowing us to make it through the gate (so, not wanting to waste a clear sky, we unloaded and observed from the long NSC driveway – the field being too far away to want to risk carrying scopes around).

3. Joint Nottingham/Corcoran Observing Session @ Corcoran High School – 6 December 2015


A shining example of Murphy’s Law of Astronomy – “If you schedule it, it will be cloudy. If you cancel, it will be clear.” The session was scheduled for December 4th, with the 5th and 6th as alternates. The 4th was a wash, and the 5th looked to be – until we cancelled the session, after which those who still attended reported having an hour of clear skies for observing. We set the 6th as a make-or-break session – which mostly broke. Despite a busy 70 minutes with 18 attendees, we were only able to catch a poor view of the Andromeda Galaxy and a moderately washed-out view of the Pleiades. The discussion more than made up for the weather, however, and we plan to return again to try our luck near the heavily lit Corcoran High School football field (sadly, Nottingham High School does not fare much better).

4. Geminid Meteor Shower @ Baltimore Woods – 13/14 December 2015

As far as reported observing, this session went solely to Bob Piekiel at his special session at Baltimore Woods. With a one hour clearing on the evening of the 13th, Bob and his two attendees managed six bright meteors and a number of deep sky objects before packing it up. The 14th, sadly, was not an option for observing due to increased cloud cover, meaning CNY, yet again, largely missed out on one of the great meteor showers.

The 2016 calendar is getting populated and plans are in the works for more sessions. Stay tuned and Happy New Year!
