TransNeptunian Object A/2022 T1 = comet C/2022 T1 (Lemmon). Cometary activity discovery.

Looks that trans-Neptunian object A/2022 T1 discovered in October, 2022, is active. I started observations early this year and for now its activity became obvious: a tiny 8.1" tail at PA 310 deg is visible on a sum of 5 images 120 sec each received today using a [T72] 51-cm telescope in Chile (iTelescope observatory).
Cometary activity report is submitted to MPC (I used 247 code here as the observatory has no MPC code yet).

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.
