Object/Date:
C/2021 A1 (Leonard) @ 2021 November 4, 11:49 UT

Description:
Comet C/2021 A1 (Leonard) imaged on November 4, 2021, since my previous image its look has changed dramatically: in just two weeks its brightness has increased from magnitude 11.5 to 10, its coma has increased in angular size from 4' to 9' having developed an strong outer halo of intense green color, and its tail has grown from 5' to 16' in length. Everything continues signaling that the comet is very active and it keeps the expectation of being observable at naked eye in December.

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.
