A warm welcome to all friends of comets and minor planets!
We are living on a beautyful planet, surrounded in space from its large and small
brothers and sisters since unimaginable times.
The importance of the amateurs'
collaboration in the follow-up
observations of NEOs is immense
For me as an amateur, participating in the measurement of near-earth bodies is definitely inspiring for my demanding hobby

NEO Apollo 2020 KJ4 was passing the Earth on May, 25 2020 in
0.086249 AU distance ~ 12,902,666 km ~ 80,173,455 miles
Here you can see a gif animation of this small object:

Comet C/2019 Y4 (ATLAS) is probably starting a desintegration process.
There are two dots westward the central condensation. The comet tail is looking more and more like a cigar.
Here you find a light curve of the comet on CometasObs showing a decrease of the central magnitude since March, 28 2020
In comparison an image of comet C/1999 S4 (LINEAR) during its desintegration process... and one week before
The small body passed a weak galaxy cluster in the Western edge region of constellation LEO close to the bounder of CANCER
Confirmation of a new comet published on the PCCP on July,22 2018, video of July, 25 2018
The object was published first as object A107IQ9 on the PCCP (Possible Comet Confirmation Page), first detected by T08 ATLAS-MLO, Mauna Loa, Hawaii on July,22 2018
TEST YOUR EYES!
The comet is moving from left to right between the arrows. One loop with arrows, 3 loops without arrows, endless. One loop = 1.25 seconds.
