Arp 34 - Coma Berenices

[Mike JW]

There are so many wondrous sights up there. This one is from 2 nights ago.  (Cleaned up in photoshop). Mike

Constellation: Coma Berenices

Classification: Galaxy in S-shape (integral sign)

Name: NGC 4615 (4614 to left, 4613 below)

Mag: 13.1

Distance: 230 million lyrs away

Type: Scd

Comments: All three galaxies (all spirals) are at about 230 million lyrs away and form a true group. Why is 4615 S-shaped? Some sort of interaction or it is that way naturally?

Much star formation in NGC 4615. (knots evident)

Excellent. Outstanding detail for EEVA.

Nice one. I have a shot of this (similar exposure) from a few year's back which confirms the presence of the strange sticking out bit! On the DSS2 image that part is quite blue suggesting recent star formation, presumably being the part most disrupted. Apparently class Sc spirals have loosely-wound spiral arms that give rise to an S shape

I hadn't noticed the ring in the neighbour until you pointed it out. Excuse the dust and the pattern noise...

 

The integral sign reminds me that I must post Arp 253 from the other night which contains a 'percentage sign' galaxy in the field!

Hi Martin, useful link to galaxy classification.
