This is my first color image of C/2023 A3 (Tsuchinshan-ATLAS), and it reveals some interesting features about this comet, which could potentially be the brightest in recent years. The orientation of its 2.5 arc-minute long tail indicates that it is composed of dust, as it trails behind the orbital path. There is also no noticeable gas emission in the form of a green or blue envelope; instead, there is a strongly condensed coma with a lot of dust, giving it a white-orange coloration. Its peculiar oblong shape is likely due to the special viewing angle we have these days, as Earth is currently crossing the comet's orbital plane. In this image, its brightness is magnitude 10.5, and with a bit of luck, it could reach near magnitude -1 next september. Though predicting comet brightness is risky, it's almost certain that we'll have a beautiful large dust tail in sight.

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.
