Comet C/2018 F4 (PANSTARRS): discovery of a fragmentation

Comet C/2018 F4 (PANSTARRS)
2020 Sep. 12.57 UT m1=14.3 (UCAC-4 converted to R) Dia.=1.7' Tail=2.5' in PA 175 deg; [T30] 0.51-m f/6.8 astrograph + CCD;
iTelescope observatory, Q62 (remotely from Siding Spring, Australia)

Discovery of nucleus fragmentation:
MPEC 2020-S77 : Comet C/2018 F4 (PANSTARRS)

"3 images of comet C/2018 F4 (PANSTARRS) obtained today remotely using a [T30] 0.51-m f/6.8 astrograph
(iTelescope observatory, Q62, Siding Spring, Australia).
The nucleus is fragmented. Distance between 2 components is appr. 7".
Comet is still bright and brighter than expected. Total brightness measured is 14.3 mag.
Photometry based on a conversion from an R-filter magnitude (UCAC-4).
Comet passed perihelion on Dec. 4th, 2019 (283 days after perihelion). Now it is 4.298 AU from Sun."

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.
