I was going to head out, but it didn't. Infact, I was going to go to my site and do a big planetary session. Looks like I didn't miss much. I knew the seeing was going to be trash. Ridiculously tightly packed isobars across southern Australia wedged between a low south of Tassie and a high in the bight, and complete Jovian atmosphere-like jetstream casserole above. A week ago, models showed a big strong high planted smack over SE Australia, but ofcourse we ended up with malarky instead. Tassie had winds of nearly 160km/h. Says it all.

It has been a long long time since I posted on the forums, but I have been imaging each year!

I had great success in Brisbane, despite pea soup seeing, which miraculously tidied up just as the transit was ending.

This is a quick single green channel image from my EdgeHD 925 and ASI290MM, 1540.6 UT.

Super stoked with the data I got which I'll process whenever I can this week, and I feel privileged to have seen this, hearing all the reports of unusable seeing or cloud around Australia!

Lots of imaging from Sunday night through to early Monday morning. Seeing was very poor. Had to work today so lots of processing over the next few days. Will post anything decent. Anyway, it was lovely watch the show.

That looks really good. Can't wait to see more.

Late to this, but I’m visual, so no images to share.

Having lost the conjunctions of Jupiter-Saturn and Venus-Mars to surgery and foul weather, was determined not to miss this. Chillagoe, FNQ, was the place to be, though cloudy at first, clearing only about 9pm, but winds wrecking seeing for a while. Then it settled, with excellent seeing until near the end. Arrived very late afternoon, with just enough time to check into accommodation and then scout a place outside town to set up the 130mm refractor with Denk binoviewer. Used only the Kson 16.8mm eyepieces.

Callisto was very clear against Jupiter, and its shadow crossing the GRS. Ganymede too, a little less distinct, but outside the occultation could see Europa only as white spot within the edges of Jupiter, but clearly beside Ganymede’s shadow as both neared exit. Also timed Io’s disappearing into shadow and re-emerging. All timings taken to compare against Stellarium when I get home - but having a few days off.

Really excellent experience, making up for bad year, but sorry I can’t share more than verbal description. I really appreciated you photography people sharing images about what I’d missed before.

Still got to go through a lot of subs but it looks like I might have a sharper one of the contact hopefully.

Yep - that is a good candidate, you got this on Marc.

Some are good, some are bad but some are pretty cool. 48 footages done, 68 to go. It's going to take me ages. What was I thinking?

You're a good man Marc, nobody else across Australia appears to have been able to get a clear shot of the event...

Pull this off and you could be famous

Nah... I'm already famous for my French crêpes.
I'm waiting on Krishan series. Those QLDers hogged all the seeing to themselves.

I'm waiting on Marco Lorenzi in Singapore - he took some exceptional images of a recent Ganymede/Europa occultation, and was right on top of the triple transit/occultation.

Hopefully he will be posting soon...

He just did. This is insane!

He must have masked the moons to isolate them. Pretty clever trick. You need some serious sampling to do that though.
PS: Oh that was the 8th My bad.

Cristopher Go from the Phillippines has posted some excellent images of the Europa / Ganymede interaction from Monday morning, over on the ALPO website, Jupiter section. Said he had clear skies and steady seeing, has captured albedo features on the discs of the moons as well.

Sorry for the delay putting up the link to the ALPO, had a golf game to get to . Click on Jupiter in the left hand menu and go the the 15th and scroll through all the images.

That methane filter seems to work quite well to separate the moons from the planet background. And you can still see the shadows clearly.

Europa - Ganymede transit + static shots

Here's my efforts from Sunday night. Bit disappointed with the seeing. Started sort of ok but ended up in pea soup pretty quick. Oh well, good training for the next one. There are a couple of things I'll do differently.


2118-2120UTC [276KB]

0024-0213UTC [3.7MB]

0239-0348UTC [6.5MB]

Added some static shots. Anything after 2:00am was shot in real bad seeing but comparing to the same timestamps in Stellarium it seems legit. You can see Ganymede going in front of Europa then Europa re-emerging bright then eclipsed again but by Ganymede shadow then re-emerging. By then it's pea soup territory and at 40 degrees elevation westwards. It's a real shame. I hope Marco got something super sharp.

Hi Marc

I enjoyed watching those animations, #2 in particular was excellent for the conditions.

You still managed to resolve details on the satellites of Jupiter which is quite an achievement given the seeing conditions you endured.

I think the extra 6.6 sq cms aperture area of the 212 over the 210 really helped.

A lot of hard work, both outdoors and indoors, but it has given you a good record of this rare event.

Cheers

Dennis
