Jupiter - Saturn Conjunction Series : watch now or wait till 2080

How rare are Jupiter-Saturn conjunctions? And how often are they getting close as 6.1 arcmin?
I searched the internet and found this link : https://sparky.rice.edu/~hartigan/public-night/jupsat2.html  


When looking at this list we see that a simular conjunction took place in 1563 BC and 709BC. We also see some real close encounters in 372 and 1226 BC and it is believed that this could be observed.

How close is 6.1 arcmin, the distance next december 21, 2020? Tom compare, the moon is about 0.5° or 30 arcmin. I used software Stellarium to make this more visible using the field of view of my ASI224MC camera and my 80/480mm telescoop with barlow x2


The next close Jupiter-Saturn conjunction will take place in the year 2080.
