Object/Date:

C/2019 L3 (ATLAS) @ 2021 March 12, 02:41 UT

Description:

Comet C/2019 L3 ATLAS imaged on March 12, 2021. It is the first image I took of this comet, which must be huge since it still is located almost 5 U.A. from Earth and its brightness is at magnitude 12. Unfortunately its perihelion will be very far, to 3.5 U.A. from the Sun in early 2022 when it could reach between magnitude 9 and 10. In the image is seen a strong condensed coma with 35 arcseconds in angular size and a short northward tail. Complete the scene, of course, the planetary nebula M 76 (the Little Dumbbell Nebula) to the right of the bright red star of magnitude 6.6.

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.
