President's Comments
If you’re like most people around here, you must have
joyfully greeted the change in weather that has finally
come to us here on Long Island. It has been notably
one of the longest winters that we’ve had in quite some
time. I hope that it’s not going to be the new norm here
because it was so bad that my observing time was
severely restricted for the last 6 months. Our Spring
hopefully will run for a while more so that we can enjoy
the weather for a time at least.
Now that it is Spring, it’s time to think about nominations
for the election to be held at the Annual Meeting on
June 7th at the end of the season. Nominations were
accepted through April 23 for all open positions. You can
contact any one of the three election committee persons,
John Speroni, Annette DeGiovine-Oliveira or Rich Huber,
with any questions. John has been holding his cards
close to the vest even with me, but he did reveal that we
have at least one person running for each of the open
positions and one contested position so far. It is noteworthy that there has been one change in the constitution to allow for the process to be more transparent and
that is the part that basically says that all nominations
have to be done before the annual meeting so that members will have time to know who the candidates are well
in advance of the vote.
There will be one notable change and that is the position of secretary, Justine Haupt has graciously taken
over the helm of Custer Jamboree Chairperson and is
dedicating herself to putting on another great event in
the Fall. Thanks Justine and if there is anyone else out
there who would like to get in on the action and hasn’t
said so already, please contact her. Let’s not forget to
give George Lamonga a big thank you for getting the
ball rolling for the last two years either. It’s not easy and
at times probably quite a stressful responsibility.
Despite the weather there have been a few new things
by Bill Bogardus
happening. Our invitation to the Amateur Radio enthusiasts to come share their passion with us at Custer has
been accepted. In much the same manner as we share
space and fellowship with AOS and ASLI, the members
of PARC (Peconic Amateur Radio Club) will be present from time to time using the radio equipment and the
tower to put antennas. We’ve been working out a few
minor details as things have been going well so far. We
need to remind ourselves that we do more than just
astronomy and in fact, the amateur radio has been a big
part of Custer in the past. PARC recently made a $200
donation to Custer and we are truly appreciative to them
for their generosity.
Another big thank you goes to Dave Barnett for taking
the lead in getting our new telescope storage shed for
all those extra telescopes that we are blessed to have
around for outreach. We now have a place to keep yet
another Obsession “Big Dob” telescope at our facility. In
addition to the 25” in the Dome loaned to us by Suffolk
Community College, we have a mutual agreement that
allows us to use Tom Pennino’s 20” on the grounds too.
This is great to have another big scope to help with the
crowds.
Another project that is in the works, is to finally have live
video using the Mallincam on the Rowan scope which
is now mounted in the North Bay, With a little help from
others, Dave Barnett has done it again and gotten it all
together and running.
Finally, slowly but surely, Ricco has been getting his
twin refractors back together after the long hiatus.
Here’s hoping that it won’t be much longer. With all of
this, it’s fair to say that things are looking up at Custer.

Calendar of Celestial Events
May 5, 6 - Eta Aquarids Meteor Shower.
The Eta Aquarids is an above average shower. In the
Northern Hemisphere, the rate can reach about 30
meteors per hour. It is produced by dust particles left
behind by comet Halley, which has known and observed since ancient times. The shower runs annually
from April 19 to May 28. It peaks this year on the night
of May 5 and the morning of the May 6. The first quarter moon will set just after midnight leaving fairly dark
skies for what should be a good show. Best viewing
will be from a dark location after midnight. Meteors will
radiate from the constellation Aquarius, but can appear
anywhere in the sky.
May 14 - Full Moon.
May 24 - Possible Meteor Storm.
In the early morning hours of Saturday, May 24, the
Earth will pass through the debris field left behind by a
small comet known as P/209 LINEAR. Astronomers are
predicting that this interaction may result in a brief but
intense burst of meteor activity that could range from
dozens to hundreds of meteors per hour. Nothing is
certain, but many mathematical models are predicting
that this could be the most intense meteor shower in
more than a decade.
May 28 - New Moon. (Nice and dark for observing!)
May 10 - Saturn at Opposition. The ringed planet
The Moon will be directly between the Earth and the

Astronomers aren’t the only evening vistors at Custer!
A sneak peek at the Jamboree and a message from the Jamboree Chairperson...
I’m excited to be leading the Jamboree organization
this year and I expect it to be a noteworthy event. I’m especially
pleased to announce that this year (and possibly subsequently), we will place an emphasis on radio astronomy. While the
momentum that led to this change could be described as happenstance, I believe this might have the effect of carving out a
niche for the Custer Jamboree in a region that already has access to events like NEAF and Stellafane. This may be particularly timely considering Custer’s new affiliation and friendship
with the Peconic Area Radio Club, which while not astronomyrelated per se, represents a parallel and engaging avenue for
STEM interest and outreach.
festivities would return to Custer before the last talk of the day,
which will take place immediately following a banquet catered
in Stokes Hall at Custer, and not at a restaurant as has been
past tradition.
The main Saturday events will once again take place at
the Eastern Campus of Suffolk Community College, and talks
throughout the weekend will entail a mixture of both radio and
visible light astronomy. What’s more, after a recent productive
Jamboree planning meeting, it was decided that the Saturday
I hope to see everyone there October 17-19th, and if
you have an interest in helping make it a success please contact me or attend our next meeting (keep an eye out on the
“listserv”: http://www.custerobservatory.org/yahoo.htm).
The weekend will naturally kick off on Friday evening,
at Custer, with a group poetry reading by Bob and Steve Chapin (bring your favorite astronomy poems, or write one of your
own), and will conclude on Sunday with a relaxed day of talks
and solar observing at Custer, including a bagel breakfast. Personally, Sunday was my favorite day last year and I hope we
can recapture that air for this year.

Type 1A Supernova, SN2014J,
in Galaxy M82 (NGC 3034)
For the first time, since 1987, a star has
exploded in a “nearby” galaxy!
The supernova in 1987, SN1987A, in the nearby dwarf
galaxy, the Large Magellenic cloud, was an important
step in the understanding of the physics inside of stars.
It was the first, close supernova since the invention of
the telescope. There were theories that many neutrinos would be released during the core-collapse, and
should have reached earth prior to the photons (visible
light). This was confirmed by looking back at the data
collected, on dates before the light of the supernova was
discovered, from three underground neutrino detectors,
Kamiokande II under the Japanese Alps, IMB in a salt
mine in Ohio in the United States, and Baksan under the
Caucasus. The supernova was discovered by Ian Shelton and Oscar Duhalde at the Las Campanas Observatory in Chile on February 24, 1987. It brightened to
magnitude 3 and was visible to the naked eye for those
in the Southern Hemisphere.
Of the 1058 neutrinos produced inside the star, and
1015 per square meter that passed through the earth,
only 12 neutrinos were detected by Kamiokande II, 8 by
IMB ad 5 by Baksan, for a grand total of 25 neutrinos.
That’s it. 25 neutrinos. And all over a span of several
seconds. But that was all that was needed to prove the
by Steven Bellavia
theory. It could have easily been missed.
This recent supernova, SN2014J (“J”, for the 10th supernova discovered in 2014) was discovered by accident
on January 21st, 2014, by astronomer Steve Fossey, of
University College London while training four undergraduate students, Ben Cooke, Guy Pollack, Matthew Wilde
and Thomas Wright, on the use of a 14-inch telescope
and CCD camera at University of London Observatory.
This new supernova may also provide valuable data,
through spectroscopic and visual analysis. I don’t know
if neutrinos have been detected. Though the galaxy
M82 is close, at “only” 12 million light years away, it
is still much further than the Large Magellenic cloud,
which is only 168,000 light years distant. At 70 times the
distance, we would be 5,000 times less likely to capture
the neutrinos. And for SN1987A, only 25 neutrinos were
recorded. I am sure much data will be pouring in over
the next several weeks.
I was fortunate that I had just imaged galaxy M82 just
three weeks prior to the supernova in M82, so I have a
“before” and “during” photo. The recent photo was taken
on January 23rd, when the supernova was about magnitude 11.5. It is predicted to brighten to as much as 8.0
by January 29th.
Types of Supernovae
Supernovae are divided into two basic physical types:
Type Ia.
These result from some binary star systems in which a carbon-oxygen white dwarf is accreting matter from a
companion. (What kind of companion star is best suited to produce Type Ia super novae is hotly debated.) In a
popular scenario, so much mass piles up on the white dwarf that its core reaches a critical density of 2 x 109 g/
cm3. This is enough to result in an uncontrolled fusion of carbon and oxygen, thus detonating the star.
Type II.
These supernovae occur at the end of a massive star's lifetime, when its nuclear fuel is exhausted and it is no
longer supported by the release of nuclear energy. If the star's iron core is massive enough, it will collapse and
become a supernova.

Video Astronomy Installation
On Saturday April 5, 2014, visitors to Custer
were introduced to Custer’s reconfigured
north bay in the white Observatory Shed. A
Mallincam video camera was installed on the
north bay pier. The Mallincam takes the place
of an eyepiece and allows multiple people to
simultaneously view the same target on a
television.

sky. Visitors with limited mobility who have
difficulty climbing two flights of stairs to the
main dome, or cannot safely enter the small
doorways of the ASLI and AOS domes, may
be able to access the ground-level Observatory Shed.
The original Mallincam installation was done
using a Schmidt-Cassegrain Telecope (SCT)
and f3.3 focal reducer. This setup functioned
but Custer volunteers concurred that the 8”
fast Newtonian astrograph built by Steve Bellavia would be a better pairing with the Mallincam. The astrograph was relocated to the
north bay on April 19 and successfully used
for views of Jupiter, Mars, and double stars in
spite of hazy observing conditions.
Continuing improvements include painting
the walls black and adding curtains at the door
to keep light from the television from interfering with observing on the south lawn. We are
also considering adding a second telecope
to the mount, so visitors can view the same
object on the television and through an eyepiece to directly compare video astronomy to
visual astronomy.
This new video astronomy installation benefits Custer guests in many ways. Visitors now
have one more instrument to look through on
busy nights, decreasing queues at other telescopes. Video astronomy can display deep
sky objects that are to dim to see in an eyepiece. Custer lecturers can point out details
on the screen while talking about the night
Many Custer members assisted with this
project. Thank you to all who helped with
planning, cleaned clutter from the north bay,
and installed equipment. This progress is especially welcome after the cold, icy winter.
The remainder of the shed is also being improved. Rico Verticchio’s homemade big
binoculars (“big” is an understatement; see
photo) in the center bay were recently refurbished due to damage from Long Island
humidity. We also plan to improve the flow
of foot traffic and refurbish the south bay 14”
Schmidt-Cassgrain telescope.

Keith Rowan
(9/8/1960 – 4/8/2010)
Astronomer - Teacher - Friend.
I met Keith in Holy Ghost elementary school, on 46th
street and 17th avenue in Brooklyn.
I don’t remember what grade we became friends. I think
it was around 6th grade. We both had an interest in
science and astronomy. There was another friend, Gary
Laverty, who also had this same interest. The three of
us quickly bonded and spent much time together. People called us “The Three Musketeers”.
by Steven Bellavia
For all of us, astronomy was our passion. I kept it as a
hobby, but Keith followed that passion much further, and
earned his bachelors and masters in astronomy, going
to school at night while working as a park ranger by day.
Keith ultimately became an astronomy professor and ran
the observatory at the College of Staten Island.
We made our own telescopes, purchasing Pyrex mirror blanks from Edmund Scientific Company, along with
grinding powders and books, etc. We made our own
equatorial mounts out of plumbing pipes. Even under
the light-polluted skies of Brooklyn, we would observe
the planets, the moon, the sun, and sometimes even the
Orion nebula.
We entered science fairs together, taking many firsts,
always as a team.
I know all the students and faculty had tremendous
respect and admiration for Keith. His thoroughness and
enthusiasm, in everything he did, was inspiring.
His license plate and E-mail were both “SKYGAZER908”, 9/08 being his birthday, which oddly enough
was the last time I spoke to Keith in 2009.
We would take train rides into Manhattan to go to the
Hayden Planetarium. We tried to watch every science
show there was on television, usually annoying our
parents and siblings, who would rather watch something
else, and we would have to negotiate which house we
would watch them at, often taking turns.
As we grew older, we went our separate ways. Gary
went to California, I moved to Long Island to work for
Grumman Aerospace, and Keith became a New York
Park Ranger. I heard that many of the manuals and
books he produced, cataloging and describing various
aspects of fauna, flora and geology of the state parks,
are still used as training material for new hires as well as
reference sources for seasoned veterans.
Gary left us very early in life, and that was sad for Keith
and me. And in 2010, Keith left us too. He was only 49.
He had planned a trip to China for the July, 2009 eclipse,
but a heart problem kept him from going. He had successful bypass surgery, but died, unexpectedly less than
a year later, in his sleep.
I built the 8-inch astrograph in dedication to Keith, my
first and oldest friend on this earth.
