Four of Six!  A fabulous Adirondack Astronomy Retreat

  

            This year’s Adirondack Astronomy Retreat was our most successful yet.  Out of six possible nights, substantial portions of four of them were dark, sharp, and clear during our 7th annual Retreat held August 6-12.  Of these nights, the final one was the best.  It didn’t start that way, however; in fact during that whole lazy afternoon, thick cirrostratus clouds seemed unwilling to break up.  Moreover, all the forecasts we checked that afternoon  agreed that the clouds would stay.  I disagreed with all of them.  I thought that these clouds were not thickening, and often when that happens the clouds dissipate towards evening,  And that is precisely what happened.  At 9:30 that evening the sky was completely cloudy, by 10 there were small holes in the cloud cover; by 10:10 there were large holes in the cloud cover, and by 10:30 the sky was completely clear!  Nice.  

            Not only was the last night clear, but also it marked the maximum of the Perseid Meteor Shower for 2010.  This was far from a scientific count—it was really just for fun.  Our observer count ranged from one to six or seven as the night went on.  These meteors came in spurts; we would see several within a few minutes, then enjoy breaks during which the sky was quiet.  Although at no point did the numbers of meteors reach storm levels (1 meteor or more per second), there were several periods during the night when the rates reached a few per minute.  Over the course of that last night we counted 271 meteors—an extraordinary number.

This was not the only night we counted meteors.  

Vince Mateo took this marvellous piucture of a Perseid streaking over the retreat, night of August 6/7, 2010. 

 

During the two retreats that week we informally counted meteors on several nights.  Our second night of the first retreat, during which we counted 92 meteors, coincided with what we call “VIP night” when senior officials of the University that owns the camp, the State University of New York at Plattsburgh, joined us for a fancy evening meal.

At this event we also officially opened, after a long seven-year wait, the David H. Levy Observatory’s Cutting pavilion, named after the family of an amateur astronomer who  built the building and used it for many years.

  It was a very good, emotional ceremony.  In my remarks I expressed the strong sense of accomplishment I have whenever a new observatory, a new member of my astronomical family, is dedicated.  We even had a contest to name the telescope; the winning entry was Aart, for Adirondack Astronomy Retreat Telescope, and thus a new “child” telescope begins to inspire people to look toward the sky.

 

I could’ve sworn it was Heaven.

Just about everyone who has visited Twin Valleys Camp has been struck by its sheer majesty.  This year, as Wendee and I drove up the road, the observatory building was the first thing we saw.  “Now that’s where the observatory belongs!” I said when we first caught sight of it.   “Front and center.”   The observatory reinforces the profound impact the site has.  The “Twin Valleys” name implies that the site consists of two valleys, one which contains the camp, the other which is empty save for the foundations of a long-deserted farm.. In between the two valleys are a series of low mountains across which hikers enjoy walking long well-marked trails.   One of these trails leads upwards to the rim of Ferguson Mountain, where Horseshoe Ledge offers a stunning view of the entire camp.  I’ve been up there several times over the years, even taking some pictures to prove it.

You can experience the magic of this place yourself next summer.  Our retreat dates will be July 31-August 6.  Contact This e-mail address is being protected from spambots. You need JavaScript enabled to view it for details.

As wondrous as the camp is, its real magic comes at sunset.  As the sky begins to darken the place takes on an eerie, otherworldly mood.  As I look around the same thought invariably enters my mind:  I love this place.  I love everything this place offers, especially its peace, relaxation, and a sense that all is right with the world.

 

Sharing the Sky Web Log 17: The Summer of 2010 begins.

CN3y Sharing the Sky Weblog No. 16
The Summer of 2010 begins
            Sharing the Sky becomes very active during the summer months, particularly when we conduct our annual Adirondack Astronomy Retreat. In a few days, people and telescopes will start to arrive at the Twin Valleys Campsite for a week of friendship, discussion, and most of all, observing. 
            If the sky is clear on Saturday, August 7, we will gather at dusk to begin observing what could be one of the best Perseid meteor showers in years. The radiant rises just after dark in the northeast, and climbs higher and higher with each passing hour. Thus, our count of meteors should also increase as the night goes on. The Perseids and I go back a very long way; I first observed them on the night of August 12, 1962 from the original Jarnac Site in Quebec, and over the course of the night I counted 112 meteors. The meteors sometimes came in pairs as if one speck of dust broke into two as it entered the upper atmosphere. The Perseids are the best shower of the year in the northern hemisphere; with summer nights being warm and pleasant, the sky show is often outstanding.
            The Perseids are not the only activity for the retreat this year. Many participants will have their own telescopes and cameras, and so astrophotography should be a big part of what we do. In fact, Wendee has arranged a slot of time each afternoon for anyone who has pictures to show to display them for all to see. Since our first Retreat in 2004, each year a group of men including Vince Matteo, Greg Taylor, Bob Masterson, Bill Olear, Steve Durham, Martin Rice, Bradley Feldman, and others have come, observed visually, and taken some of the most stunning photographs I have seen. They normally remain nameless, but Wendee calls them “the guys”, in honor of their having been part of the retreat since its beginning. 
            This year, Saturn will also be in the evening sky, pretty close to Venus. Saturn is a favorite object because of its ring system. “Exquisite!” seems to be the best word to describe this magnificent sight of a planet surrounded by “a thin, flat ring, nowhere touching” as Christian Huygens wrote when he discovered them in 1655.   I remember arguing the point a few weeks ago with someone at the Royal Astronomical Society of Canada, who insists that Galileo discovered them. Neither his telescope nor his eyesight were good enough to see Saturn as other than a triple-planet which gradually turned into a single object, then reemerged as a triple years later. Looking at Saturn is one of the most satisfying things that one can do with a telescope.
            I’ll write more about this year’s retreat when it ends. In the meantime, let’s hope this one comes with a clear sky and lots of fun.

CN3y Sharing the Sky Web Log 16-- A Fabulous General Assembly

A Fabulous General Assembly


Getting together with fellow stargazers is one of the best things about being a stargazer. Yesterday, while flying home from the General Assembly of the RASC, I realized how much fun I had in the preceding few days. This year, the 10-year-old New Brunswick Center sponsored the General Assembly. Held on the University of New Brunswick campus in Fredericton, New Brunswick, the program updated its delegates on astronomical advances, on the latest trends in observing hardware, and a lot on needs and methods of astronomical education. One of the highlights of this meeting was a presentation by the astronomy group at the Miramachi Rural School. These young people, with the help of Adam Hayward, their enthusiastic teacher, have built an observatory, installed a telescope, and have turned their astronomy class into an interactive project that has most of Miramachi under the stars. These children presented something so magical and exciting that their presentation earned them a standing ovation from the delegates.
Most of us stayed at the Joy Kidd residence on the University of New Brunswick campus, which was also the site of the BBQ dinner and the several parties that featured astronomical songs sung by Peter Jedicke and his sidekick, me. The Wu Center, where all our meetings were held, was comfortably air conditioned.
At lunch on that day, I was honored to be able to present my paper “A Nightwatchman’s Journey: My Life and Hard Times” as a comet seeker.” It was a retrospective of the 45 years I have spent comet hunting so far. For the first time talking to a national audience, I also recounted the highlights of the observatory crisis in 1967, when, at the age of 18. I was nearly expelled from the RASC. I do recall deciding to give up astronomy at that time, but I am glad I didn’t. The crisis was precipitated when Isabel Williamson accused me of bresaking the centre’s antique barograph. My repeated denials were ignored, and I was nearly expelled. It was a difficult time, but ten years later I began a correspondence with Miss Williamson that turned into a friendship that lasted to the end of her life in 2000. That friendship included a conversation about the RASC National awards during which I discovered that she had never received the RASC service award. Miss Williamson did receive it a few months later. All in all, Isabel K. Williamson was one of the central figures in the RASC during the generation before ours. Her efforts and strength of character have recently been noted by the Society.
A real highlight was a visit to what is likely the first astronomical observatory in Canada. The Brydone-Jack observatory is named after William Brydone-Jack, a professor of mathematics and later president of the university. Thanks to Brydone-Jack’s efforts, Fredericton was the first location in Canada to have its longitude accurately calculated.

There was a central personal reason for this meeting, said Chairman Paul Gray. It was a thank you party for two of his mentors, outgoing national President David Lane and incoming President Mary Lou Whitehorne. He ranks these two highly on his list of mentors who helped him get into astronomy and keep him there, and especially into his beloved hobby of supernova searching, which has now yielded several discoveries of supernovae shining from distant galaxies.

However, more than anything else, Gray sees the RASC as a national family, filled with people who love the sky and love to watch it.

This is the key to enjoying the RASC. Besides looking up at the night sky, it is the people we meet and the friendships we make that render it all worthwhile.

Sharing The Sky WebLog 14-- Star Night Near Sleepy Hollow

Star Night at Mercy College

 

David H. Levy Doveed

 

            On April 19, 2010, 49 years after my Bar Mitzvah in 1961, Sharing the Sky celebrated its first Star Night at Mercy College.  Located in Dobbs ferry, a town north of New York City and next door to the Village of Sleepy Hollow, site of Washington Irving’s famous legend from 1820, this institution is the recipient of the first telescope STS has been able to give away in a number of years.  The telescope awarded was a “David Levy Comet Hunter” 6-inch f/5 Maksutov-Newtonian reflector.  It has a near perfect primary mirror whose secondary is supported by a correcting lens.  The well-constructed tripod arrived a few days before I followed with the optic tube.   

            Unlike the big event we have every spring in Tucson, this Star Night was designed for a small audience.  About 25 people showed up for the event and for the lecture that preceded it.  The purpose was to announce the availability of a new course about astronomy, literature, and music, and also to promote the general astronomy course the college already has offered for several years.

Though small, this audience was highly motivated.   They were attentive and interested in the story of how astronomy and literature can be related by means of a personal story.  To them, it seemed perfectly natural that a passion for one field, like astronomy, should not preclude an interest in a second area, like literature.  Using examples from literature I have studied, I told them about how Jane Eyre, in order to catch an early morning coach to Lowood School,`could not have dressed by the light of a half-moon setting in the west, unless she was dressing at midnight.   I was proud to point out this Bronteian slip, which was really not an error at all from someone familiar with the phases of the Moon.  One participant suggested that Brontë included this “mistake” on purpose, to test the alertness of her readers.  It would be interesting to find other tests scattered throughout the great novel.  I also mentioned how Lord Byron, in Canto X of Don Juan, predicted how

“…full soon

Steam-engines will conduct him to the moon.”  

 

In these two simple lines Byron predicted the mighty December 1968 launch of Apollo 8, the first craft to carry humans to the Moon, 150 years later.  

During the lecture I described a number of things we would be doing together at Mercy.  At the top of my list was the idea of evening observing sessions.  A first step: naming the telescope.  A telescope’s mirror is its beating heart, and to award it that piece of individuality one must give it a name.  After a year of trying to eke out a name for the Meade 14 at Corona Foothills Middle School, the best the kids could come up with was “Uncle Guy.”  The folks at Mercy had loftier goals, and quickly suggested Athena, the Greek goddess to whom the Parthenon was dedicated.  After the lecture was concluded, Athena and the group went outdoors for our first observing session.  We gazed first at Saturn.  Even though the eyepiece yielded an abnormally low power, we could still make out the thin ring emerging from last year’s ring plane crossing during which the planet, in its 29-year orbit of the Sun, caused its ring system briefly to vanish.  Our second target was a field of stars between Pollux and its neighbor Castor.  To me it is a field with which I was quite familiar, for that is where I turned a different telescope on my first night of comet searching, on December 17, 1965.  Next came the bright star Pollux, one of the two bright twin stars of Gemini. We closed with a look at Mizar, the magnificent double star in the Big Dipper’s handle.

Mercy has plenty of space from which one can enjoy the stars.  We began on the field between the library and the Hudson River, and then headed to the east side of the library and finally found a spot surrounded by trees that was comfortably dark.

I hope this particular Star Night will be the first of many.  Mercy College has a very good astronomy program, one that is trying to merge the purity and beauty of the night sky with some of humanity’s ageless accomplishments in literature and in music.  As we listen to the simple notes of Beethoven’s Sonata in A (Moonlight), or imagine Shakespeare viewing the great new star of 1572 (which he hints at in the opening lines of Hamlet), we gaze at the starry sky with renewed enthusiasm and optimism.
