Jupiter - GRS + Ganymede tonight 6pm

[iceman (Mike)]

Hi guys.

Tonight (barely nighttime) at 6pm AEST, Jupiter will be showing us the GRS transit, plus a ganymede disc + shadow transit.

It will barely be dark at 6pm, but Ganymede will have transitted off the disc of Jupiter, and its shadow will still be visible with the GRS, as shown in the attachment below (5:59pm AEST).

Worth a look, or an imaging attempt, if you can get out at that time.

I'd like to try and image it, but 6pm is happy hour at our house with 3 kids dinner, bath and bed time.

As well as not quite dark Jupiter will be very low in the sky to add to our woes. Won't stop me trying to get a squiz though

take a pic peeps!
good find mike

That's 8pm for us.. Perfect
Better get the scope out to cool down.
Cheers

Dont forget the aerogard. Our mozzies start swarming around that time.
LOL

Well, it was really dancing around and generally at an angle I wouldn't have even tried at BUT I saw it

Tried my hand at sketching the results and have attached them. Ganymede was just a bump on the top right of Jupiter but I could see the black dot of a shadow in some of the better moments.

Great find Mike

What software are you using Mike to predict these events?

[Robby]

Seeing was shocking here, so no images. The'd be a blur anyway. 0/10 The nor-wester has just picked up, and that's is the death too seeing. Be interesting to see if Gary got anything.

Bit different for us here in South Oz, GRS is almost gone and so too is the shadow.

Geoff you don't need any software, just google for "Jupiter GRS transit" and you should find it.
Here you go I've done it for you....http://home.mira.net/~reynella/skywa...ky.htm#Planets

Starkler, the software is Jupiter2...

OK,
as Robby said, seeing here was shocking, with the actual eyepiece view hopeless. I was certainly able to see the dark spot on the disk, but could not see the GRS.
Shot a few with the Powermate, my standard setup, and then tried an O-25mm with E/P Projection, giving a smaller image scale.
Not perfect, but always nice to see and capture such an event.
I am hoping that the seeing is responsible for the Onion Ring trend, otherwise I am out of ideas.

Way better than me Gary,
I shot a few, and there were a blur, and as such didn't bother posting! I then hunted over the moon for awhile. A very cool thing to try. Hooked up the scope at f/25 (2.5x powermate) and just cruised around the moon with the slew at 2x, with the image on the screen. I felt like a little moon rover... Shot a few landscapes and have yet to process them, but seeing was even worse than on Jupiter, bouncing all over the show!.
Cheers

Seeing here was very good tonight, did not get a Jupiter with GRS or the shadow, but did get some nice jupiters and Saturns. Am processing now so will post them in solar system section.
