This future publication research note provides details and descriptions of a peculiar extragalactic object near the galaxy PGC1850831 in the constellation of Boötes. An interesting object was posted on the Legacy Survey Discussion website on Oct 19, 2023, 6:44 PM (See topic 7247) - This research note provides a very peculiar, and probably an extragalactic object. It is faint, large, and irregularly extended, following the galaxy PGC1850831 about 1.5 arcminutes. The position of this peculiar object is located at:
RA = 214.6801
DEC = +28.9395
CHARACTERISTICS: The object is faint, large, and extended with two bright spots, the brightest on the north and south sides reveal that this object is probably a fragment of a smaller galaxy that merged with PGC1850831, as denoted by its disturbance and the shell features. If it is a galaxy, then it would be very peculiar and irregular, resulting from an interaction with the lenticular galaxy PGC1850831.
A POSSIBLE EXPLANATION FOR THIS OBJECT: The peculiar object following PGC1850831 is probably a fragment from the aftermath of an interaction between two galaxies. It could be that the fragment is probably moving very fast as simulations conclude it a possible case. Unfortunately, there is no other data available on this object.

Above is araw cutout of the object from the DESI Legacy Imaging Surveys, DR9 grz. The two bright portions may be connected to form a single object.
The second image regards the fragmentation is indeed two brighter parts, after adjusting the brightness and contrast settings.
The Third Image reveals the two brighter portions receive what looks to be connected to each other.
