Volume 342
COMET IS DEAD
Comet ISON dies in Sun’s fiery embrace.
The comet raises hopes, dashes them, raises them again and then wafts off into history as a “coulda been”.
Proving once again- if such proof is needed- that comets are
the contrariest of creatures, Comet ISON made its dash into
the glare of the Sun- seemed to hesitate long enough for us to
assume that it had been destroyed- and then reappeared. The
joy of seeing what might have been a magnificent sight for
Northern Hemisphere observers soon turned to disappointment as its short-lived brightness evaporated in a few hours.
The remnants of the comet, mostly dust and small rubble, will
now drift slowly off into history, while astronomers and comet junkies scan the skies for the next Greatest Comet Known
To Mankind. We live in hope.
ISON (C/2012 S1) was, naturally enough, expected to be
brightest around the time it was closest to the Sun; but since
it was less than 1° from the Sun it couldn’t be seen, except by
the satellites that were watching the Sun. They provided dramatic images of the passage of the comet, its disappearance,
re-emergence and then dissipation.
Although we have not had mass suicides as a result of the
comet’s appearance and early demise, we have still had the
crazies out there. Grabbing the comet and shaking it like a
rag doll for all they can get out of it, they still try to explain it
away as a sign of the Coming, or the Harbinger of Whatever.
Thus, the gibberish from one silly website:
For thousands of years, civilizations have believed that
Comets were signs that strange changes were inbound. For
the last 30 years or so, Astronomers have tried to ‘debunk’
that idea. Well, it’s 2013. You’ve got America, the bastion of
Freedom getting involved in another civil war in the middle
East, Central banks controlling the Economy, Oil companies
satisfied the best energy of the day is still from 1880, Banks
have been declared too big to prosecute, Honey Boo Boo and
Kim Kardashian fill the American Boob Tube mind as Reality Television assimilates everything, Volcanoes popping off
like prom dresses after the dance, strange Solar activity in
the double peaked minimal Solar maximum, Lazarus comets
returning to life from the grave yard, Sink holes galore, Gold
Iphones, Skynet growing larger, Drone armies expanding by
the hour, animal deaths in mass quantities, bizarre weather,
over all anger and confusion amongst the masses......,”
Above: SOHO’s images of the comet at the end of November. After swinging too
close to the Sun ISON sped away, flinging debris widely and brightening before dissapating into hsitory. Fustibus stellae mortuus est. Icarus knew a thing or two.
Below: the comet in October on its way to its eventual fate near the Sun.

With the school holidays upon
us shortly it should be a good
idea to take the kids along to
the local Observatory for an
evening. All major cities have
at least one- and many astronomical societies arrange ‘open
nights’ occasionally.
* * *
Some frankly amazing images
are filtering out from amateur
astronomers using the latest
imaging devices mounted on
remotely-controlled automated telescopes. Astro-imaging
should best be described as a
multi-disciplinary challenge.
There are increasing numbers
of people up to the challenge. It
gets better all the time.
* * *
Who is the first amateur astronomer to be immortalised as the
subject of a question in Professor Shatterini’s famous quiz?
* * *
Some people need to change their medication. It was just a
lump of ice and rubble. There’ll be another one coming along
soon...... and maybe it will be the Comet of the Century.
CHINA SENDS THE JADE RABBIT TO THE MOON.

Well, that was something of a
disappointment, wasn’t it? After all the hype, all the expectations and all the crossed fingers the comet fell to pieces just
when things were beginning to
look good. Ah well, there’ll be
another ‘world’s greatest ever
comet’ coming along sooner or
later.
China has launched a lunar probe, the Chang’e-3, carrying their first Moon
rover which is named after the mythical rabbit that lives there.
Jade Rabbit, has six wheels and will survey the Moon’s geological structure
in the northern hemisphere. The rover is the most advanced ever sent to
the Moon and is equipped with ground-penetrating radar When the probe
lands on the surface of the Moon’s northern hemisphere in mid-December
it will be the first ever Chinese spacecraft to soft land on an extraterrestrial
body, the first Moon lander launched this century and will be carrying the
first (remotely controlled) telescope to be sent to the moon.
This mission presages a new era in space exploration. China intends to have
astronauts land on the moon within ten years. China will launch its first
lander towards Mars within twelve months. In June this year it launched
the Shenzhou 10, its fifth manned spaceflight and successfully returned the
three astronauts to Earth two weeks later. They had practised docking with
the Tiangong unmanned space station. The slow and steady pace of their
space exploration is a noticable feature of Chinese astronautics.

With the Chinese space administration fixing its eyes firmly on
the Moon, it won’t be too long
before the Americans ramp up
their efforts to get back there.
What’s the betting that there’ll
be a Maccas in the next crater
from the local Chinese restaurant within twenty or so years?
Nothing like a bit of competition to make people ramp up
the effort.

WHAT’S YOUR REAL STAR-SIGN?
Your star sign is supposed to be obtained by finding when the Sun is in
your ‘house’. Problem is that the Sun, and everything in the galaxy is slowly
moving. The Sun and all the stars are slowly moving around our galaxy in
a stately merry-go-round. It takes two hundred and thirty million years for
this to happen. As a consequence everything changes, including the constellations. So, look up your birthday date below and find your new star sign!

COMET-EATING SUN GETS
BUSY WITH STRONG FLARES
The Sun poses many puzzles – some yield to a bit of sleuthing; others remain inscrutable. We recently saw a complex group that survived its transit
of the Sun’s ‘far side’ to become much more active during its second passage
across the visible disc (AR11890).
Now (November) we are seeing a group that has survived its far-side transit
to become an enormously large spot, but has been stripped of most of its
earlier complexity. This is AR11899 – once part of October’s large and active group, AR11875.
During this earlier disc crossing (as AR11875) it hosted two GOES
class-X flares (the strongest kind) and many lesser ones; a dramatic X2.3
flare with the group just behind the NW limb showed a range of amazing
H-alpha transients, discussed here earlier. Would it return we then asked?
Yes- it would!
AR11899. On Nov 12 (21:19 UT) a truly huge spot was logged at
the eastern limb - as a long thin ellipse due to our line of sight. The next day
allowed a more informative view (Fig, log 2).
“Helio” freeware sited the newcomer at +6,39 and gave it the huge
area (for a single spot) of 550units! What was the giant’s story?
Activity ‘nest’. In H-alpha there
were signs of complexity: a long filament (arf) stretched from the spot
northwards 5 degrees and faculae
covered much of the disc east of
the big spot. This showed that the
big spot was part of a large activity area, now mostly spotless - and a
GOES C3.1 flare erupted along the
filament at 23:08UT: clearly the site
was not dormant.
It was soon clear that the
newcomer was the return of the
large preceding (p) spot of AR11875
– and that all (or most) of the many
following (f) spots of that group
were now gone: yet the ‘old’ group
was still capable of flaring!
The Fig, log 1, shows the large (p)
spot of AR11875, 17 days earlier,
with the few remaining (f) spots
omitted for clarity: its area was then
420 units. When it passed the west
limb 3 days later the few (f) spots
were gone. Note that all the small
spots attending the big ‘smiley’ spot
were of violet polarity.
During its October transit of the disc the (p) spot of 11875
had very strong violet polarity, V26
(2600G). As it passed the west limb
there were some signs of new red
polarity near the big (p) spot and
a striking light-bridge had divided
its umbra (not shown). Then - it was
gone for two weeks.Return. During ‘far-side’ transit it seems the
group had changed and new flux
(spots) of opposite ‘sign’, i.e. ‘red’,
had emerged near the old (p) spot
(see log 2) on the eastern side, with
values R13 – 15 in a tiny cluster of
spots. And east of the main spot was
the large filament that hosted the C
class flare. The returnee was now
dubbed AR11899.
A stronger M1.0 flare erupted in
it on Nov 15 at 02:29UT but was
missed by the writer. By the 17th Mt
Wilson logged a very strong 2700G
(V27) field in the main spot: the
strongest umbral field for any spot
group in SC24 thus far.
Unseen events. Is this strong field
the start of a revival of sunspot
fields for SC24? I hope so – but
guess it is just a surprising ‘oneoff’. Still, somehow during its time
hidden from view, the big (p) spot
of AR11875 not only survived but
also grew larger and its field grew
stronger! This is not quite the norm
for relic (p) spots.
Also, recall that it had 6o of westward proper motion during that
time – more than is usual, suggesting other unseen events.
As I write the flaring in AR11899
seems to have waned – but I’ll be
keeping one eye on it when viewing in H-alpha, just in case! Note
how big and dark it is on the Sun’s
disc (WL filter users only). I suspect
more action is yet to come.
Clear skies! Harry

MEL GETS ALL ARTY AND
TRIES HER HAND AT SCULPTING
High in the southern December
sky is the constellation Sculptor,
which was created by the French astronomer Abbé Nicolas de Lacaille
in 1752. It was originally named
L’Atelier du Sculpteur – ‘the sculptor’s workshop’ and many Latin
variations of this name appear on
19th century star maps. Sculptor
contains the southern pole of the
Milky Way, which is 90° from the
plane of our Galaxy.This means that
when we look in the direction of
Sculptor we can see many faint galaxies, unobstructed by the stars, gas
and dust of the plane of the Milky
Way. Amongst these faint galaxies
is a member of our Local Group,
the Sculptor dwarf, but before you
go peering down your nearest large
aperture telescope, this galaxy can
only be seen in long exposure photographs on very large telescopes.
The stars that make up sculptor are
relatively faint, with Alpha Sculptor is shining at magnitude 4.3, but
there are a few worth a good look:
Eplison (ε) Sculptoris is a binary
system with the main star having a
magnitude of 5.3 and its companion
8.6, making it visible in small aperture telescopes. It is estimated that
the stars have an orbital period of
approximately 1,200 years and this
system lies 89 light years from us.
Kappa1 (κ) Sculptoris is a close binary star of magnitudes 6.1 and 6.2.
These white/yellow stars lie about
224 light years away and a telescope with an aperture of 10cm or
greater is needed to clearly resolve
this pair.
R Sculptoris is a semi-regular variable star that ranges in magnitude
from 5.8 to 7.7 over a period of
about one year. It’s deep-red colour
makes this star quite distinctive and
it is within the reach of binoculars
and small aperture telescopes. It lies
about 1,500 light years away.
S Sculptoris is another variable star.
It is a red giant, Mira type variable
that ranges from magnitude 5.5 to
13.6 over a period of a year. At its
brightest it is well within the reach
of binoculars and small aperture
telescopes, however as it dims a
medium to large aperture telescope
would be required. It lies about
1,500 light years from us.
While Sculptor has some interesting
stars, it is best known for its galaxies, many of which make wonderful
telescope objects and respond well
to astrophotography from dark sites
with modern astro cameras.
NGC 253 is the jewel of Sculptor.
It is a magnitude 7, nearly edgeon spiral galaxy. It is nearly half
a degree long and while it can be
picked up in binocular, an aperture of at least 100mm is required
to just make out the smudge of
the spiral arms. A medium aperture telescope will start to resolve
detail in the spiral arms and the
dark dust lanes in the arms, especially on the western side of the
galaxy. There are 3 distinct stars
that surround the galaxy, which
is often referred to as the Silver
Coin galaxy. NGC 253 lies about
13 million light years away.
NGC 55 is a magnitude 8 spiral
galaxy. Like NGC 253 it is nearly
edge-on. One half of the galaxy
(western side) is brighter than
the other. Medium aperture telescopes show more detail in the
spiral arms and a brighter, elongated central region. An Oxygen
III (OIII) filter will reveal three
bright Hydrogen II (H II) regions,
just visible as hazy spots near the
centre of the galaxy. It lies about
6 million light years away.
NGC 288 is an unusual, irregular
group of stars, that is a globular
cluster, proving that appearances
can be deceiving. Most of the
globular clusters which orbit our
Milky Way have tightly packed
cores, however NGC 288 is in a
minority of low-concentration
globular clusters whose stars are
more lossely packed. A 10cm aperture telescope will reveal faint
stars amongst the haze of the
cluster. NGC 288 is about 30,000
light years away.
ESO 350-G40 is best known as
the Cartwheel Galaxy. It is a small
ring galaxy, with faint spokelike features that radiate from
a bight nucleus. The Cartwheel
has 2 companion galaxies, one of
which is the cause of the amazing
appearance of this galaxy. This
object is very faint even through a
30cm aperture telescope and the
companion galaxies are barely
visible on a good night. An aperture of 40cm reveals a hint of the
outer ring with a small nucleus.
Now that the warm weather is
here, spend a few nights hunting
down a few marvelous faint fuzzies this summer. Oh and don’t
forget to look out for that yearly,
one-night-in-December phenomenon - Santa and his reindeer of
course! Seasons Greetings to all!

Neptune: is in Aquarius
in the western evening

it looks tiny it has seventeen times
the mass of the Earth but just slightly
more gravity.
Pluto: was given a noncore promise of permanent
status which was promptly withdrawn
after the election. He’s looking for
somewhere to stay until Snowden
finds him a nice hidey-hole.
ISON was not a core promise, so we
can delete it and move onwards. It is
officially gonski. Next please!
Comet Lovejoy is next in line, making its dash around the Sun just
before Christmas. It isn’t going as
close as ISON and will therefore
probably survive its trial by fire.
However, its path outward from
the Sun will take it away from us
Southern Hemisphere observers,
so we probably won’t get much of
a view.
Next please...........

FIRST LIGHT WITH NEW QSI CAMERA AT NARRABRI
Hey Don,
that comet
was a dead
loss for
the popular
press.
December
Christoph Brem at Narrabri took the first images with his new QSI 683 camera recently. He described
it as “a simple 5x600s Halpha image of the Rosette Nebula, calibrated with 30x600s master dark and
a 100 exposures master bias but no flats, and very little processing. “......... which to many of us means
that he produced an excellent image first time out with a new camera on the back of his TeleVue
NP101is telescope. Some of us would describe the image as ‘excellent’!
The Rosette Nebula is a large region located near one end of a giant molecular cloud in the Monoceros
region of the Milky Way Galaxy. The open cluster NGC 2244 is closely associated with the nebulosity, the young stars of the cluster having been formed from the nebula’s matter.
The cluster and nebula lie at a distance of some 5,200 light-years from Earth. The radiation from the
young stars excite the atoms in the nebula, causing them to emit radiation themselves producing the
emission nebula we are able to see.
