Very nice Jupiter sketch dweller! How high above your horizon when you sketched it?

Hi David,

A nice sketch, thanks for sharing it.Considering the low altitude here in the UK, Jupiter has so far been pretty good to view.

Dweller,

Wonderful Jupiter sketch. You captured much detail considering how close to the horizon Jupiter was.

Thanks for the kind comments.

In the UK Jupiter was just 21 degrees high on the 14th.

I used to image but find I now prefer to draw.

Clear skies.

Here is my first try to sketch Jupiter. The seeing was very bad (the planet was 21° high). It was also my first sketch in colour. And it is fun to do (if my kids don't need the same colour!).

Me too. It was hard to get that feeling of being one with the universe while taking dark frames , constantly checking the guiding, watching a monitor, playing with software etc.

Oh but I digress.

Its a very good sketch

I still image but I do science not "pretty Pictures." Still it is not the same as sketching what you see. That makes it such a personal activity. If you take five people, with five identical telescopes, looking at the same object at the same time and they are the same skill level you would still get 5 different views and all of them would be accurate! It may no longer be "very scientific" but it sure is satisfying. Plus, anyone can do imaging with enough money, not everyone can make a beautiful sketch!

Dweller and Jef,

Excellent observations of Jupiter. You have both recorded the major belts (NEB and SEB) very nicely. Thank you for sharing them with us all.

Jef and dweller25,

Nice sketches from both of you. Jupiter has afforded you some nice views even at the low altitude at which you must observe it. I guess it helps that Jupiter is so huge in the eyepiece right now--almost 10x the apparent diameter of Mars, for instance.

Thanks to all for the kind words. Here is an another try from two days later (17 August 23.15 UT). The seeing was much better (by moments a steady immage by x300). There was much more detail in the NEB an SEB. And I saw for the first time the Great Red Spot. Who named it? Because it isn't red at all!!

Jef,

Very nice Jupiter sketch. It looks like you used color pencils. Good color selections.
I think the GRB was first noted by Giovanni Cassini in the mid- 1600's. I don't know if he named it. It was much more of a red in the late 1950's and early 1960's when I first observed it.

great jupiter sketch Jef i was observing the planet at the same time you were but my seeing was rather miserable. i started sketching but then gave up. i'll post the raw unfinished sketch anyway because the resemblance with yours is very obvious i found the dark streak following the grs also very prominent, as you show, just as the irregularity in the Neb!

thanks for sharing and keep those sketches coming!

Kris,

Nice sketch. I am glad to see you sketched that barge or whatever it is following the GRS. I was catching glimpses of it as I sketched two nights back.

Jef and Kris,

Excellent observations of Jupiter showing the major belts very nicely. The Great Red Spot (GRS) has appeared a very dark "brick" red color at times since it's discovery (Definitely by 1831 (S. H. Schwabe who recorded the Red Spot Hollow (RSH)) and possibly by Jean Dominique Cassini (or Giovanni Domenico) in 1665 who recorded a dark spot at the approximate latitude). The GRS becomes prominent when the South Equatorial Belt (SEB) fades as occurred in 1990 (please see my observation below made on February 6, 1990 using a C14).

The best of luck in your future observations of Jupiter.

Carlos

All thanks for the historical note on the GRS.

Frank, I finished the sketch in colour only two days later than the observation and I found it difficult to recall the exact colours. So I tried to work on the differences (this darker than that, etc...).

Kris, thanks for posting your sketch. Now I know that my eyes are allright! I'm looking forward for the years to come when Jupiter will be higher in the sky for people like us (in Belgium).

Is it normal that the belts are fading to the edge of the planet? I noted it in my fieldnotes, but didn't draw in the sketch.
