ASTRO: Arp 333

Arp 333/NGC 1024 lies in Ursa Major near the bear's nose. It is classed
as (R')SA(r)ab and is about 150 million light years distant. Arp
thought it peculiar enough for his catalog due to its extremely thin
arms but had no category for this so put it in his Miscellaneous
category. Arp 337 (M82) being the most famous member of this class.
His comment on Arp 333 reads "Thin circular arms, star in southeast
superimposed on wisp."

Inside the faint disk of the galaxy are two short blue arm segments that
are extremely thin. I don't know if he is referring to them or the
outer edge of the disk. The star at the southeast end that obscures the
"wisp" is a pain. While only the wisp is obvious in his image, mine
shows quite a bit more in this area. Is it the remains of a partly
cannibalized dwarf? I find nothing on it. If you compare my image to
Arp's at this star you will note a small reddish condensation just above
the star in my image that is missing from Arp's image. This bothered me
at first. Then I checked the DSS 2 red and blue plates. Arp used film
very similar (grainier) that was used for the DSS images using a blue
sensitive emulsion but imaging through a yellow filter much of the time.
This tended to neutralize the color to better match a true spectral
image for visual light. But it does eliminate red objects. Sure enough
the object is missing on the blue plate and present on the red. So it's
absence from Arp's image is easily explained by his emulsion choice. So
much for my "super nova" discovery.

Unfortunately, this one is outside the SDSS so there's not much
information on this area. With the two galaxies to its east it forms a
three galaxy group; WBL 082/KTG 09. The little northern spiral is NGC
1028 classes Sa by NED and SB at the NGC Project. It looks barred to me
so I doubt the Sa classification. The lower is NGC 1029 classed as S0/a
by both NED and the NGC Project.

Now while these three are considered a group NGC 1028 is small because
it over twice as far away as the other two at 380 million light years.
Thus it is only a line of sight group member. It looks like it could
have been included in Arp's One Heavy Arm category.

While there are other sizable galaxies in the image I find red shift
data on only two others. One is the edge on spiral southwest of Arp
333. It is FGC 0326 (Flat Galaxy Catalog) classed as Sd and is about
350 million light years distant. So another background galaxy as its
angular size would indicate. The other is southwest of NGC 1029 and
southeast of Arp 333 on a line through the major axis of Arp 333. It is
a small (in angular size) reddish spiral. Like all the other identified
galaxies in the image but without distance data it is from the 2MASS
survey, 2MASX J02392466+1045321. It lies twice as distance yet again at
about 750 million light years. I find no classification on it.

Fantaastic detail in the core - I imaged this group with the five inch
refractor and didn't capture any detail in the core. Need to revisit
it with the 10 inch.

Your seeing is often better than mine so you should do rather well with
it with the larger scope.

Three inches of rain today and forcast is for unsettled weather
through the coming week.

Weather pattern still unusual in for this time of year - good to have
the rain though.

Nice thing about being almost a year behind in my processing is I'm
processing stuff that is currently or soon will be in the sky! This is
an interesting field if you can go deep enough.

Though since I'm automated some of my images are taken at 4 a.m. which
is fine for an automated system but no way I'd do it manually!

Rick,

coming to think of it I don't really know where the bear keeps it's nose :-)
NGC 1024 reminds me a bit of M106.
And did I mention that you got some really good detail in this image?
