Arp 63 and Arp 129

One from the archives. I always meant to go back and get some more time on this one but you know ---- may never happen! So here's what I've got.

Arp 63 is an example of two Arps in one field. Arp 63 is the little group in lower centre of the field, while the object about 3.5 arc minutes NNE is Arp 129. Arp 63 is in Dr. Arp's class 'Spirals with Small HSB Companions on Arms'. There are actually three galaxies involved, two almost fully merged and the one to the SE possibly interacting. Apparent magitude 14, surface brightness 21.9 - faint! Size 1' x 24" - small!

Arp 129 is in the class 'E-like Galaxies Perturbing Spirals'. The E-like galaxy to the east is MCG+6-21-72 (mag.16, size 0.5' x 0.5') and the spiral to the west is MCG+6-21-71 (mag. 14, size 0.8' x 0.5'). The pair is cataloged as UGC 5146.

Clearly a tricky target, even for an Arp, needs a lot more exposure time eventually.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
