Object of the Week Feb 05, 2012 - ARP 143 "Genie in a Bottle"

ARP 143 AKA NGC 2444 NGC 2445

LYNX

NGC 2444 MAG 14.2 SO PEC
NGC 2445 MAG 13.9 IM PEC

I have heard these galaxies called the "Genie in a Bottle" but not often. NGC 2445 has lots of knots and bright H II regions. I wonder how many can be seen? NGC 2444 has a bright nuclei and a very faint plume going to the north. There is lots of suttle detail in this pair of interacting galaxies.

I was looking on the SDSS at this object and found something very interesting in the Plume of NGC 2444. What I found was a back ground Quasar 17.5 V MAG. this would be a good challenge object. I would like to hear your reports on this object. The Quasar is at a Z.616.

GOOD LUCK And GREAT VIEWING!

Ah, the Remarkable Extragalactic System NGC 2444-5

Check out this 1959 journal article by the Burbidges and the image taken with the 82-inch at McDonald

I Did not Know that the Burbidges were ever at McDonald.

Thanks Steve ill have to check out the old logs in the Library.

Cute galaxies, Jimi! I've looked them a few times. Most recently Jim and I observed them in February 2011 from the Texas hill country. At first, they appeared as two interacting galaxies. They showed some of the brighter knots. Of course, the Big O located them first and provided an excellent view but we also had Jim's magnificent obsession (the 30") and we got a surprise. NGC 2445 appeared to consist of two connected lobes. A third galaxy, LEDA 200237, is part of NGC 2445. We were excited about seeing the third galaxy and never even noticed any quasar.

Hi Ana,

Great to see you here!

Thanks for the heads up on the LEDA galaxy. Ill have to track that one down.

Welcome Ana! We're glad you've signed up!!

I'm excited about DSF!

Hey Jim..
I've heard some AMAZING things about your observatory and it's instruments. That is a fantastic photo. Did you take these through the 48"?

Hi Jimi,

great OOTW. Unfortunately I don't know the pair with my 27", but it was also impressing with the "old" 16". I could see detect one knot in NGC 2445 (I think the S knot is a star?), see sketch.
The Quasar is a very cool detail, but 17.5vmag seems very faint. Looking at the SDSS it seems to be fainter than 17.5. I have to give it a try.

CS, uwe

Uwe WELCOME to DSF

Nice sketch.

You should put some of You're fantastic sketches in the Sketches and Image thread.:)

Adrian R WELCOME to DSF,

I do not do imaging with the 48" its a visual only scope;)


The Image is from the Sloan (SDSS).
