Comet C2019-Y4 ATLAS Animation - 10 April 2020

Another animation of Comet C2019/Y4 Atlas. Compared to shots I took earlier in April, it does indeed appear that the comet is breaking up. The well defined coma is no longer there and its just a fuzzy ball.

Got a better view of the tail this time due to better conditions as well as using a monochrome camera instead of OSC (Thanks Chuck!)

**Updated** I uploaded a new version that adjusts the histogram to counter the light pollution. See the original version for the LP problem outlined below....

Of note from this animation is the lightening of the frames towards the end - classic example of light pollution as the person that lives behind me has a massive bright light that points into my yard and comes on randomly, sometimes, like this at 1am..... so frustrating...

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.
