Excellent! Very nice with the conjunction.
I would like to know when the circular will come out, what are they waiting for?

Dear Roberto, all,
I was able to obtain a new set of images of this object last night via LCO-Tenerife. Both single and stacked images show a small condensed coma and a distinct, straight tail up to 35 arcseconds long in approximate p.a. 285.
The attached image is a single 300-second exposure, cropped to approximate dimensions 12x12 arcminutes. The prominent galaxy is NGC 2365.
Sincerely,
Alan
Great that you confirmed. Did you send the observation with confirmation to the MPC?

Hi Roberto, all,
Nice job Roberto!
I can confirm that this object is exhibiting cometary behavior. On images I took yesterday with LCO-Tenerife (0.35-m Cassegrain) it is clearly showing a small condensed coma and a short westward-pointing tail. Attached image is 300-seconds, 5x5 arcminutes, standard orientation (north up, east right), taken December 8 at 23:58 UT.
Sincerely,
Alan
Object 2015 CD60 is definitely a comet.
From images taken on December 2nd (unfortunately analyzed only today)
I noticed that the object 2015CD60 (object that I follow together with others to see if it has cometary activity) is definitely a comet with a tail too!
These are the data of the object:
2015CD60 Mag. 18.0 for a coma of about 10" with a tail of about 42" in PA 277¡ã.
Photo data:
Taken with a 369mm Cassegrain reduced to F/6.88 (2493mm focal length) on December 2nd 2024 (mean time 01h12m22s UT) with 46x90s and a limiting magnitude of about 22. Image scale 1".24/pixel north up but slightly tilted to the left by 4¡ã and east therefore to the left. Field of 21'.6x32'.3.
I also took it on November 1, 2024 and it showed no activity (it was even more difficult to understand due to the presence of many annoying stars nearby).
