Jupiter - 6.8.2022 at 02.05 - 6.8.2022 at 02.07 Vantaa, Pähkinärinne Observation number 108105

Visibility Unclassified

Paula Wirtanen, Ursa (Helsinki)

Now it was time to start the Jupiter observing season for my part. The finder tube had to be fine-tuned a bit and salute Saturn before starting to study Jupiter

The attached observation is directly from the form. The air directions are as they are seen through a telescope through an angle prism (north at the top, mirror image; in the future I will publish my observations in the "basic position", i.e. south at the top as the object appears in the telescope without an angle prism).

The observation itself is crude, admittedly, and the time I spent on drawing observation was maybe two minutes. It's a little, but the clouds started to accumulate so much that the conditions became bad and you couldn't really distinguish details from Jupiter. With such a small amount of detail, I don't feel that I am satisfied with the observation, but something can be concluded from this as well.

First, the Great Red Spot was turning away, but still visible. Its darkness has been exaggerated in the drawing, but it was still quite clearly visible as a dot slightly darker than the background. The SEB, i.e. the southern equatorial belt, was also clearly darker than when I observed Jupiter last fall.

The NEB, i.e. the northern equatorial belt, stood out quite dark and I could see some kind of bulge in it.

It's good to continue here and I'm publishing this observation, which goes far beyond practice, in the spirit of teaching. You can read about observing Jupiter on the hobby group's Jupiter website and in Zeniit, which appears at the end of August and September.

But, even if you don't distinguish those details, Jupiter's four largest moons are always great to watch. It can be done even with a lower magnification. I made a drawing observation of the porch for the same connection (I = Io, II = Europa, III = Ganymede and IV = Kallisto).

It's good to continue with this and hopefully you'll see a better drawing from me this autumn too.
