Hi Roberto,
?
Yes, I did.
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.
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
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).
