Jupiter in the Southeastern Summer Sky new
      #3983560 - 08/14/10 11:19 PM Attachment (47 downloads)



It was one of those moonless summer nights that should be pretty decent for deep sky observing or observing in general. I was out assessing conditions for a later rendezvous to view some Perseid meteors. In the meantime the urge to sketch was strong and so far this year I have not even given Jupiter more than a casual look in a small scope.
Jupiter was about 30 degrees above the horizon which is often good enough for at least a close look.
I discovered when I finished that if I had waited another hour I could have included the GRS in the sketch.
The northern equatorial belt was very dark brown and the near loss of the southern belt was a surprise even though I knew it would not be there.

Sketching:

Telescope: 10" f/5.7 Dob. with 6mm ortho. 241x
White Strathmore 400 series recycled paper 9" x 12"
Various graphite pencils and erasers
Jupiter: 2010, August, 13 4:45 – 5:40 UT
Distance 4 AU
V. mag. -2.8
Dia. 47.26"
Alt. above horizon 30°
Transparency: 7/10
Seeing: 6/10

Frank,

An excellent observation of Jupiter showing a good amount of detail. You have recorded the North Equatorial Belt (NEB) and bright and dark condensations and rifts within it very nicely. The thin SEB northern border and polar regions are also nicely recorded. Thank you for sharing it with us all.

I placed your fine observation on a dark background and rotated it as well. I hope that you like it.

Carlos

Very nice Frank, I tried to view the GRS last night but clouds stopped play. I shall enjoy your drawing instead.

Carlos, Thank you for straightening out Jupiter and putting it on a dark background. It was very nice to spend some time observing this large orb.

Excellant Jup sketch Frank, i was observing jup also and the seeing was great very steady, i watched the grs cross the planet later that night, jup was about the best that i have ever seen it,jup does pass higher overhead when it has a winter oppostion but the the winter skies are so poor that i prefer the summer oppositions, anyway the grs is a darker orange-pink this year and the grs jr is easier too see as a dark hollow has sort of formed around it,anyway your planetary sketching is much improved you have really captured the diagonal rift in the neb and some of jup more subtle , thanks again for posting.

Tommy5,

Thank you, Jupiter was performing well that night even though the mosquitoes were just terrible. I hope to spend a little more time with Jupiter very soon.
Glad to hear you are getting in some quality observing time.

Frank

Frank,

Terrific sketch of the King--you really captured the South Polar region and NEB nicely.

Amazing how big Jupiter appears compared to teeny Mars, isn't it?

Tom, Michael, Sol,

Thank you all for your kind words and comments.
I think sketchimg Mars earlier this year has made the Jupiter sketching easier. Thanks for pointing that out to me Michael. I had not thought about it until you mentioned it.

Jim,

Thank you, I'm looking forward to another opportunity.
Hope your observing over there in Michigan is going well.
