It will take 12 more years before Jupiter gets this close to Earth on Sep. 20

NASA website recently published the page "Closest Encounter with Jupiter until 2022", which tells us that on the night of September 20 - 21 Jupiter will shine much brighter than usual as it will be 75 million kilometers closer than in past encounters.

So, if you are lucky enough to have a clear sky on the night of September 20, it would be a great opportunity to observe Jupiter, if possible with a telescope so that you can directly observe features like the two red spots "kissing" or notice the stripe that disappeared in May (details in the post: "Jupiter Loses a Stripe and NASA is Mystified") which is still "missing".

I would also like to recommend the website that Mr. Friedman has, called avertedimagination.com. He has taken beautiful pictures of the planets and the solar system, using a 10" telescope from his home in Buffalo, N.Y. Some of these photos have been published in NASA pages, which is how I found about him and his site.

Given that tonight has been clear, I hope tomorrow our luck continues so that we can have a chance to see Jupiter even through all the city lights. Clear skies for everyone on this close encounter with Jupiter!
